 # Components Guide
-{%

+
+In `pydase`, components are fundamental building blocks that bridge the Python backend logic with frontend visual representation and interactions. This system can be understood based on the following categories:
+
+## Built-in Type and Enum Components
+
+`pydase` automatically maps standard Python data types to their corresponding frontend components:
+
+- `str`: Translated into a `StringComponent` on the frontend.
+- `int` and `float`: Manifested as the `NumberComponent`.
+- `bool`: Rendered as a `ButtonComponent`.
+- `list`: Each item displayed individually, named after the list attribute and its index.
+- `dict`: Each key-value pair displayed individually, named after the dictionary attribute and its key. **Note** that the dictionary keys must be strings.
+- `enum.Enum`: Presented as an `EnumComponent`, facilitating dropdown selection.
+
+## Method Components
+Within the `DataService` class of `pydase`, only methods devoid of arguments can be represented in the frontend, classified into two distinct categories
+
+1. [**Tasks**](./Tasks.md): Argument-free asynchronous functions, identified within `pydase` as tasks, are inherently designed for frontend interaction. These tasks are automatically rendered with a start/stop button, allowing users to initiate or halt the task execution directly from the web interface. 
+2. **Synchronous Methods with `@frontend` Decorator**: Synchronous methods without arguments can also be presented in the frontend. For this, they have to be decorated with the `@frontend` decorator.
+
+```python
+import pydase
+import pydase.components
+import pydase.units as u
+from pydase.utils.decorators import frontend
+
+
+class MyService(pydase.DataService):
+    @frontend
+    def exposed_method(self) -> None:
+        ...
+
+    async def my_task(self) -> None:
+        while True:
+            # ...
+```
+
+![Method Components](../images/method_components.png)
+
+You can still define synchronous tasks with arguments and call them using a python client. However, decorating them with the `@frontend` decorator will raise a `FunctionDefinitionError`. Defining a task with arguments will raise a `TaskDefinitionError`.
+I decided against supporting function arguments for functions rendered in the frontend due to the following reasons:
+
+1. Feature Request Pitfall: supporting function arguments create a bottomless pit of feature requests. As users encounter the limitations of supported types, demands for extending support to more complex types would grow.
+2. Complexity in Supported Argument Types: while simple types like `int`, `float`, `bool` and `str` could be easily supported, more complicated types are not (representation, (de-)serialization).
+
+## DataService Instances (Nested Classes)
+
+Nested `DataService` instances offer an organized hierarchy for components, enabling richer applications. Each nested class might have its own attributes and methods, each mapped to a frontend component.
+
+Here is an example:
+
+```python
+from pydase import DataService, Server
+
+
+class Channel(DataService):
+    def __init__(self, channel_id: int) -> None:
+        super().__init__()
+        self._channel_id = channel_id
+        self._current = 0.0
+
+    @property
+    def current(self) -> float:
+        # run code to get current
+        result = self._current
+        return result
+
+    @current.setter
+    def current(self, value: float) -> None:
+        # run code to set current
+        self._current = value
+
+
+class Device(DataService):
+    def __init__(self) -> None:
+        super().__init__()
+        self.channels = [Channel(i) for i in range(2)]
+
+
+if __name__ == "__main__":
+    service = Device()
+    Server(service).run()
+```
+
+![Nested Classes App](../images/Nested_Class_App.png)
+
+**Note** that defining classes within `DataService` classes is not supported (see [this issue](https://github.com/tiqi-group/pydase/issues/16)).
+
+## Custom Components (`pydase.components`)
+
+The custom components in `pydase` have two main parts:
+
+- A **Python Component Class** in the backend, implementing the logic needed to set, update, and manage the component's state and data.
+- A **Frontend React Component** that renders and manages user interaction in the browser.
+
+Below are the components available in the `pydase.components` module, accompanied by their Python usage:
+
+### `DeviceConnection`
+
+The `DeviceConnection` component acts as a base class within the `pydase` framework for managing device connections. It provides a structured approach to handle connections by offering a customizable `connect` method and a `connected` property. This setup facilitates the implementation of automatic reconnection logic, which periodically attempts reconnection whenever the connection is lost.
+
+In the frontend, this class abstracts away the direct interaction with the `connect` method and the `connected` property. Instead, it showcases user-defined attributes, methods, and properties. When the `connected` status is `False`, the frontend displays an overlay that prompts manual reconnection through the `connect()` method. Successful reconnection removes the overlay.
+
+```python
+import pydase.components
+import pydase.units as u
+
+
+class Device(pydase.components.DeviceConnection):
+    def __init__(self) -> None:
+        super().__init__()
+        self._voltage = 10 * u.units.V
+
+    def connect(self) -> None:
+        if not self._connected:
+            self._connected = True
+
+    @property
+    def voltage(self) -> float:
+        return self._voltage
+
+
+class MyService(pydase.DataService):
+    def __init__(self) -> None:
+        super().__init__()
+        self.device = Device()
+
+
+if __name__ == "__main__":
+    service_instance = MyService()
+    pydase.Server(service_instance).run()
+```
+
+![DeviceConnection Component](../images/DeviceConnection_component.png)
+
+#### Customizing Connection Logic
+
+Users are encouraged to primarily override the `connect` method to tailor the connection process to their specific device. This method should adjust the `self._connected` attribute based on the outcome of the connection attempt:
+
+```python
+import pydase.components
+
+
+class MyDeviceConnection(pydase.components.DeviceConnection):
+    def __init__(self) -> None:
+        super().__init__()
+        # Add any necessary initialization code here
+
+    def connect(self) -> None:
+        # Implement device-specific connection logic here
+        # Update self._connected to `True` if the connection is successful,
+        # or `False` if unsuccessful
+        ...
+```
+
+Moreover, if the connection status requires additional logic, users can override the `connected` property:
+
+```python
+import pydase.components
+
+class MyDeviceConnection(pydase.components.DeviceConnection):
+    def __init__(self) -> None:
+        super().__init__()
+        # Add any necessary initialization code here
+
+    def connect(self) -> None:
+        # Implement device-specific connection logic here
+        # Ensure self._connected reflects the connection status accurately
+        ...
+
+    @property
+    def connected(self) -> bool:
+        # Implement custom logic to accurately report connection status
+        return self._connected
+```
+
+#### Reconnection Interval
+
+The `DeviceConnection` component automatically executes a task that checks for device availability at a default interval of 10 seconds. This interval is adjustable by modifying the `_reconnection_wait_time` attribute on the class instance.
+
+### `Image`
+
+This component provides a versatile interface for displaying images within the application. Users can update and manage images from various sources, including local paths, URLs, and even matplotlib figures.
+
+The component offers methods to load images seamlessly, ensuring that visual content is easily integrated and displayed within the data service.
+
+```python
+import matplotlib.pyplot as plt
+import numpy as np
+import pydase
+from pydase.components.image import Image
+
+
+class MyDataService(pydase.DataService):
+    my_image = Image()
+
+
+if __name__ == "__main__":
+    service = MyDataService()
+    # loading from local path
+    service.my_image.load_from_path("/your/image/path/")
+
+    # loading from a URL
+    service.my_image.load_from_url("https://cataas.com/cat")
+
+    # loading a matplotlib figure
+    fig = plt.figure()
+    x = np.linspace(0, 2 * np.pi)
+    plt.plot(x, np.sin(x))
+    plt.grid()
+    service.my_image.load_from_matplotlib_figure(fig)
+
+    pydase.Server(service).run()
+```
+
+![Image Component](../images/Image_component.png)
+
+### `NumberSlider`
+
+The `NumberSlider` component in the `pydase` package provides an interactive slider interface for adjusting numerical values on the frontend. It is designed to support both numbers and quantities and ensures that values adjusted on the frontend are synchronized with the backend.
+
+To utilize the `NumberSlider`, users should implement a class that derives from `NumberSlider`. This class can then define the initial values, minimum and maximum limits, step sizes, and additional logic as needed.
+
+Here's an example of how to implement and use a custom slider:
+
+```python
+import pydase
+import pydase.components
+
+
+class MySlider(pydase.components.NumberSlider):
+    def __init__(
+        self,
+        value: float = 0.0,
+        min_: float = 0.0,
+        max_: float = 100.0,
+        step_size: float = 1.0,
+    ) -> None:
+        super().__init__(value, min_, max_, step_size)
+
+    @property
+    def min(self) -> float:
+        return self._min
+
+    @min.setter
+    def min(self, value: float) -> None:
+        self._min = value
+
+    @property
+    def max(self) -> float:
+        return self._max
+
+    @max.setter
+    def max(self, value: float) -> None:
+        self._max = value
+
+    @property
+    def step_size(self) -> float:
+        return self._step_size
+
+    @step_size.setter
+    def step_size(self, value: float) -> None:
+        self._step_size = value
+
+    @property
+    def value(self) -> float:
+        """Slider value."""
+        return self._value
+
+    @value.setter
+    def value(self, value: float) -> None:
+        if value < self._min or value > self._max:
+            raise ValueError("Value is either below allowed min or above max value.")
+
+        self._value = value
+
+
+class MyService(pydase.DataService):
+    def __init__(self) -> None:
+        super().__init__()
+        self.voltage = MySlider()
+
+
+if __name__ == "__main__":
+    service_instance = MyService()
+    service_instance.voltage.value = 5
+    print(service_instance.voltage.value)  # Output: 5
+    pydase.Server(service_instance).run()
+```
+
+In this example, `MySlider` overrides the `min`, `max`, `step_size`, and `value` properties. Users can make any of these properties read-only by omitting the corresponding setter method.
+
+![Slider Component](../images/Slider_component.png)
+
+- Accessing parent class resources in `NumberSlider`
+
+    In scenarios where you need the slider component to interact with or access resources from its parent class, you can achieve this by passing a callback function to it. This method avoids directly passing the entire parent class instance (`self`) and offers a more encapsulated approach. The callback function can be designed to utilize specific attributes or methods of the parent class, allowing the slider to perform actions or retrieve data in response to slider events.
+
+    Here's an illustrative example:
+
+    ```python
+    from collections.abc import Callable
+
+    import pydase
+    import pydase.components
+
+
+    class MySlider(pydase.components.NumberSlider):
+        def __init__(
+            self,
+            value: float,
+            on_change: Callable[[float], None],
+        ) -> None:
+            super().__init__(value=value)
+            self._on_change = on_change
+
+        # ... other properties ...
+
+        @property
+        def value(self) -> float:
+            return self._value
+
+        @value.setter
+        def value(self, new_value: float) -> None:
+            if new_value < self._min or new_value > self._max:
+                raise ValueError("Value is either below allowed min or above max value.")
+            self._value = new_value
+            self._on_change(new_value)
+
+
+    class MyService(pydase.DataService):
+        def __init__(self) -> None:
+            self.voltage = MySlider(
+                5,
+                on_change=self.handle_voltage_change,
+            )
+
+        def handle_voltage_change(self, new_voltage: float) -> None:
+            print(f"Voltage changed to: {new_voltage}")
+            # Additional logic here
+
+    if __name__ == "__main__":
+       service_instance = MyService()
+       my_service.voltage.value = 7  # Output: "Voltage changed to: 7"
+       pydase.Server(service_instance).run()
+    ```
+
+- Incorporating units in `NumberSlider`
+
+    The `NumberSlider` is capable of [displaying units](./Understanding-Units.md) alongside values, enhancing its usability in contexts where unit representation is crucial. When utilizing `pydase.units`, you can specify units for the slider's value, allowing the component to reflect these units in the frontend.
+
+    Here's how to implement a `NumberSlider` with unit display:
+
+    ```python
+    import pydase
+    import pydase.components
+    import pydase.units as u
+
+    class MySlider(pydase.components.NumberSlider):
+        def __init__(
+            self,
+            value: u.Quantity = 0.0 * u.units.V,
+        ) -> None:
+            super().__init__(value)
+
+        @property
+        def value(self) -> u.Quantity:
+            return self._value
+
+        @value.setter
+        def value(self, value: u.Quantity) -> None:
+            if value.m < self._min or value.m > self._max:
+                raise ValueError("Value is either below allowed min or above max value.")
+            self._value = value
+
+    class MyService(pydase.DataService):
+        def __init__(self) -> None:
+            super().__init__()
+            self.voltage = MySlider()
+
+    if __name__ == "__main__":
+        service_instance = MyService()
+        service_instance.voltage.value = 5 * u.units.V
+        print(service_instance.voltage.value)  # Output: 5 V
+        pydase.Server(service_instance).run()
+    ```
+
+### `ColouredEnum`
+
+This component provides a way to visually represent different states or categories in a data service using colour-coded options. It behaves similarly to a standard `Enum`, but the values encode colours in a format understood by CSS. The colours can be defined using various methods like Hexadecimal, RGB, HSL, and more.
+
+If the property associated with the `ColouredEnum` has a setter function, the keys of the enum will be rendered as a dropdown menu, allowing users to interact and select different options. Without a setter function, the selected key will simply be displayed as a coloured box with text inside, serving as a visual indicator.
+
+```python
+import pydase
+import pydase.components as pyc
+
+
+class MyStatus(pyc.ColouredEnum):
+    PENDING = "#FFA500"  # Hexadecimal colour (Orange)
+    RUNNING = "#0000FF80"  # Hexadecimal colour with transparency (Blue)
+    PAUSED = "rgb(169, 169, 169)"  # RGB colour (Dark Gray)
+    RETRYING = "rgba(255, 255, 0, 0.3)"  # RGB colour with transparency (Yellow)
+    COMPLETED = "hsl(120, 100%, 50%)"  # HSL colour (Green)
+    FAILED = "hsla(0, 100%, 50%, 0.7)"  # HSL colour with transparency (Red)
+    CANCELLED = "SlateGray"  # Cross-browser colour name (Slate Gray)
+
+
+class StatusTest(pydase.DataService):
+    _status = MyStatus.RUNNING
+
+    @property
+    def status(self) -> MyStatus:
+        return self._status
+
+    @status.setter
+    def status(self, value: MyStatus) -> None:
+        # do something ...
+        self._status = value
+
+# Modifying or accessing the status value:
+my_service = StatusExample()
+my_service.status = MyStatus.FAILED
+```
+
+![ColouredEnum Component](../images/ColouredEnum_component.png)
+
+**Note** that each enumeration name and value must be unique.
+This means that you should use different colour formats when you want to use a colour multiple times.
+
+### Extending with New Components
+
+Users can also extend the library by creating custom components. This involves defining the behavior on the Python backend and the visual representation on the frontend. For those looking to introduce new components, the [guide on adding components](https://pydase.readthedocs.io/en/latest/dev-guide/Adding_Components/) provides detailed steps on achieving this.

+# Configuring `pydase`
+
+## Do I Need to Configure My `pydase` Service?
+
+`pydase` services work out of the box without requiring any configuration. However, you
+might want to change some options, such as the web server port or logging level. To 
+accommodate such customizations, `pydase` allows configuration through environment 
+variables - avoiding hard-coded settings in your service code.
+
+Why should you avoid hard-coding configurations? Here are two reasons:
+
+1. **Security**:  
+    Protect sensitive information, such as usernames and passwords. By using environment
+    variables, your service code can remain public while keeping private information 
+    secure.
+
+2. **Reusability**:  
+    Services often need to be reused in different environments. For example, you might
+    deploy multiple instances of a service (e.g., for different sensors in a lab). By 
+    separating configuration from code, you can adapt the service to new requirements 
+    without modifying its codebase.
+
+Next, we’ll walk you through the environment variables `pydase` supports and provide an
+example of how to separate service code from configuration.
+
+## Configuring `pydase` Using Environment Variables
+
+`pydase` provides the following environment variables for customization:
+
+- **`ENVIRONMENT`**:  
+  Defines the operation mode (`"development"` or `"production"`), which influences 
+  behaviour such as logging (see [Logging in pydase](./Logging.md)).
+
+- **`SERVICE_CONFIG_DIR`**:  
+  Specifies the directory for configuration files (e.g., `web_settings.json`). Defaults
+  to the `config` folder in the service root. Access this programmatically using:
+
+    ```python
+    import pydase.config
+    pydase.config.ServiceConfig().config_dir
+    ```
+
+- **`SERVICE_WEB_PORT`**:  
+  Defines the web server’s port. Ensure each service on the same host uses a unique 
+  port. Default: `8001`.
+
+- **`GENERATE_WEB_SETTINGS`**:  
+  When `true`, generates or updates the `web_settings.json` file (see [Tailoring Frontend Component Layout](./interaction/Auto-generated-Frontend.md#tailoring-frontend-component-layout)).
+  Existing entries are preserved, and new entries are appended.
+
+### Configuring `pydase` via Keyword Arguments
+
+Some settings can also be overridden directly in your service code using keyword 
+arguments when initializing the server. This allows for flexibility in code-based 
+configuration:
+
+```python
+import pathlib
+from pydase import Server
+from your_service_module import YourService
+
+server = Server(
+    YourService(),
+    web_port=8080,                             # Overrides SERVICE_WEB_PORT
+    config_dir=pathlib.Path("custom_config"),  # Overrides SERVICE_CONFIG_DIR
+    generate_web_settings=True                 # Overrides GENERATE_WEB_SETTINGS
+).run()
+```
+
+## Separating Service Code from Configuration
+
+To decouple configuration from code, `pydase` utilizes `confz` for configuration
+management. Below is an example that demonstrates how to configure a `pydase` service
+for a sensor readout application.
+
+### Scenario: Configuring a Sensor Service
+
+Imagine you have multiple sensors distributed across your lab. You need to configure
+each service instance with:
+
+1. **Hostname**: The hostname or IP address of the sensor.
+2. **Authentication Token**: A token or credentials to authenticate with the sensor.
+3. **Readout Interval**: A periodic interval to read sensor data and log it to a
+  database.
+
+Given the repository structure:
+
+```bash title="Service Repository Structure"
+my_sensor
+├── pyproject.toml
+├── README.md
+└── src
+    └── my_sensor
+        ├── my_sensor.py
+        ├── config.py
+        ├── __init__.py
+        └── __main__.py
+```
+
+Your service might look like this:
+
+### Configuration
+
+Define the configuration using `confz`:
+
+```python title="src/my_sensor/config.py"
+import confz
+from pydase.config import ServiceConfig
+
+class MySensorConfig(confz.BaseConfig):
+    instance_name: str
+    hostname: str
+    auth_token: str
+    readout_interval_s: float
+
+    CONFIG_SOURCES = confz.FileSource(file=ServiceConfig().config_dir / "config.yaml")
+```
+
+This class defines configurable parameters and loads values from a `config.yaml` file
+located in the service’s configuration directory (which is configurable through an 
+environment variable, see [above](#configuring-pydase-using-environment-variables)).
+A sample YAML file might look like this:
+
+```yaml title="config.yaml"
+instance_name: my-sensor-service-01
+hostname: my-sensor-01.example.com
+auth_token: my-secret-authentication-token
+readout_interval_s: 5
+```
+
+### Service Implementation
+
+Your service implementation might look like this:
+
+```python title="src/my_sensor/my_sensor.py"
+import asyncio
+import http.client
+import json
+import logging
+from typing import Any
+
+import pydase.components
+import pydase.units as u
+from pydase.task.decorator import task
+
+from my_sensor.config import MySensorConfig
+
+logger = logging.getLogger(__name__)
+
+
+class MySensor(pydase.DataService):
+    def __init__(self) -> None:
+        super().__init__()
+        self.readout_interval_s: u.Quantity = (
+            MySensorConfig().readout_interval_s * u.units.s
+        )
+
+    @property
+    def hostname(self) -> str:
+        """Hostname of the sensor. Read-only."""
+        return MySensorConfig().hostname
+
+    def _get_data(self) -> dict[str, Any]:
+        """Fetches sensor data via an HTTP GET request. It passes the authentication 
+        token as "Authorization" header."""
+
+        connection = http.client.HTTPConnection(self.hostname, timeout=10)
+        connection.request(
+            "GET", "/", headers={"Authorization": MySensorConfig().auth_token}
+        )
+        response = connection.getresponse()
+        connection.close()
+
+        return json.loads(response.read())
+
+    @task(autostart=True)
+    async def get_and_log_sensor_values(self) -> None:
+        """Periodically fetches and logs sensor data."""
+        while True:
+            try:
+                data = self._get_data()
+                # Write data to database using MySensorConfig().instance_name ...
+            except Exception as e:
+                logger.error(
+                    "Error occurred, retrying in %s seconds. Error: %s",
+                    self.readout_interval_s.m,
+                    e,
+                )
+            await asyncio.sleep(self.readout_interval_s.m)
+```
+
+### Starting the Service
+
+The service is launched via the `__main__.py` entry point:
+
+```python title="src/my_sensor/__main__.py"
+import pydase
+from my_sensor.my_sensor import MySensor
+
+pydase.Server(MySensor()).run()
+```
+
+You can now start the service with:
+
+```bash
+python -m my_sensor
+```
+
+This approach ensures the service is fully configured via the `config.yaml` file,
+separating service logic from configuration.

+# Logging in pydase
+
+The `pydase` library organizes its loggers per module, mirroring the Python package hierarchy. This structured approach allows for granular control over logging levels and behaviour across different parts of the library. Logs can also include details about client identification based on headers sent by the client or proxy, providing additional context for debugging or auditing.
+
+## Changing the pydase Log Level
+
+You have two primary ways to adjust the log levels in `pydase`:
+
+1. **Directly targeting `pydase` loggers**
+
+     You can set the log level for any `pydase` logger directly in your code. This method is useful for fine-tuning logging levels for specific modules within `pydase`. For instance, if you want to change the log level of the main `pydase` logger or target a submodule like `pydase.data_service`, you can do so as follows:
+
+    ```python
+    # <your_script.py>
+    import logging
+
+    # Set the log level for the main pydase logger
+    logging.getLogger("pydase").setLevel(logging.INFO)
+
+    # Optionally, target a specific submodule logger
+    # logging.getLogger("pydase.data_service").setLevel(logging.DEBUG)
+
+    # Your logger for the current script
+    from pydase.utils.logging import configure_logging_with_pydase_formatter
+    configure_logging_with_pydase_formatter(level=logging.DEBUG)
+
+    logger = logging.getLogger(__name__)
+    logger.debug("My debug message.")
+    ```
+
+    This approach allows for specific control over different parts of the `pydase` library, depending on your logging needs.
+
+2. **Using the `ENVIRONMENT` environment variable**
+
+    For a more global setting that affects the entire `pydase` library, you can utilize the `ENVIRONMENT` environment variable. Setting this variable to `"production"` will configure all `pydase` loggers to only log messages of level `"INFO"` and above, filtering out more verbose logging. This is particularly useful for production environments where excessive logging can be overwhelming or unnecessary.
+
+    ```bash
+    ENVIRONMENT="production" python -m <module_using_pydase>
+    ```
+
+    In the absence of this setting, the default behavior is to log everything of level `"DEBUG"` and above, suitable for development environments where more detailed logs are beneficial.
+
+## Client Identification in pydase Logs
+
+The logging system in `pydase` includes information about clients based on headers sent by the client or a proxy. The priority for identifying the client is fixed and as follows:
+
+1. **`Remote-User` Header**: This header is typically set by authentication servers like [Authelia](https://www.authelia.com/). While it can be set manually by users, its primary purpose is to provide client information authenticated through such servers.
+2. **`X-Client-ID` Header**: This header is intended for use by Python clients to pass custom client identification information. It acts as a fallback when the `Remote-User` header is not available.
+3. **Default Socket.IO Session ID**: If neither of the above headers is present, the system falls back to the default Socket.IO session ID to identify the client.
+
+For example, a log entries might include the following details based on the available headers:

+## Configuring Logging in Services
+
+To configure logging in services built with `pydase`, use the helper function [`configure_logging_with_pydase_formatter`][pydase.utils.logging.configure_logging_with_pydase_formatter]. This function sets up a logger with the same formatting used internally by `pydase`, so your service logs match the style and structure of `pydase` logs.
+
+### Example
+
+If your service follows a typical layout like:
+
+```text
+└── src
+    └── my_service
+        ├── __init__.py
+        └── ...
+```
+
+you should call `configure_logging_with_pydase_formatter` inside `src/my_service/__init__.py`. This ensures the logger is configured as soon as your service is imported, and before any log messages are emitted.
+
+```python title="src/my_service/__init__.py"
+import sys
+from pydase.utils.logging import configure_logging_with_pydase_formatter
+
+configure_logging_with_pydase_formatter(
+    name="my_service",      # Use the package/module name or None for the root logger
+    level=logging.DEBUG,    # Set the desired logging level (defaults to INFO)
+    stream=sys.stderr       # Optional: set the output stream (stderr by default)
+)
+```
+
+### Notes
+
+- If you pass `name=None`, the root logger will be configured. This affects **all logs** that propagate to the root logger.
+- Passing a specific `name` like `"my_service"` allows you to scope the configuration to your service only, which is safer in multi-library environments.
+- You can use `sys.stdout` instead of `sys.stderr` if your logs are being captured or processed differently (e.g., in containers or logging systems).

+# Understanding Service Persistence
+
+`pydase` allows you to easily persist the state of your service by saving it to a file. This is especially useful when you want to maintain the service's state across different runs.
+
+To enable persistence, pass a `filename` keyword argument to the constructor of the [`pydase.Server`][pydase.Server] class. The `filename` specifies the file where the state will be saved:
+
+- If the file **does not exist**, it will be created and populated with the current state when the service shuts down or saves.
+- If the file **already exists**, the state manager will **load** the saved values into the service at startup.
+
+Here’s an example:
+
+```python
+import pydase
+
+class Device(pydase.DataService):
+    # ... define your service class ...
+
+if __name__ == "__main__":
+    service = Device()
+    pydase.Server(service=service, filename="device_state.json").run()
+```
+
+In this example, the service state will be automatically loaded from `device_state.json` at startup (if it exists), and saved to the same file periodically and upon shutdown.
+
+## Automatic Periodic State Saving
+
+When a `filename` is provided, `pydase` automatically enables **periodic autosaving** of the service state to that file. This ensures that the current state is regularly persisted, reducing the risk of data loss during unexpected shutdowns.
+
+The autosave happens every 30 seconds by default. You can customize the interval using the `autosave_interval` argument (in seconds):
+
+```python
+pydase.Server(
+    service=service,
+    filename="device_state.json",
+    autosave_interval=10.0,  # save every 10 seconds
+).run()
+```
+
+To disable automatic saving, set `autosave_interval` to `None`.
+
+## Controlling Property State Loading with `@load_state`
+
+By default, the state manager only restores values for public attributes of your service (i.e. *it does not restore property values*). If you have properties that you want to control the loading for, you can use the [`@load_state`][pydase.data_service.state_manager.load_state] decorator on your property setters. This indicates to the state manager that the value of the property should be loaded from the state file.
+
+Example:
+
+```python
+import pydase
+from pydase.data_service.state_manager import load_state
+
+class Device(pydase.DataService):
+    _name = "Default Device Name"
+
+    @property
+    def name(self) -> str:
+        return self._name
+
+    @name.setter
+    @load_state
+    def name(self, value: str) -> None:
+        self._name = value
+```
+
+With the `@load_state` decorator applied to the `name` property setter, the state manager will load and apply the `name` property's value from the file upon server startup.
+
+**Note**: If the structure of your service class changes between saves, only properties decorated with `@load_state` and unchanged public attributes will be restored safely.

+# Understanding Tasks
+
+In `pydase`, a task is defined as an asynchronous function without arguments that is decorated with the [`@task`][pydase.task.decorator.task] decorator and contained in a class that inherits from [`pydase.DataService`][pydase.DataService]. These tasks usually contain a while loop and are designed to carry out periodic functions. For example, a task might be used to periodically read sensor data, update a database, or perform any other recurring job.
+
+`pydase` allows you to control task execution via both the frontend and Python clients and can automatically start tasks upon initialization of the service. By using the [`@task`][pydase.task.decorator.task] decorator with the `autostart=True` argument in your service class, `pydase` will automatically start these tasks when the server is started. Here's an example:
+
+```python
+import pydase
+from pydase.task.decorator import task
+
+
+class SensorService(pydase.DataService):
+    def __init__(self):
+        super().__init__()
+        self.readout_frequency = 1.0
+
+    def _process_data(self, data: ...) -> None:
+        ...
+
+    def _read_from_sensor(self) -> Any:
+        ...
+
+    @task(autostart=True)
+    async def read_sensor_data(self):
+        while True:
+            data = self._read_from_sensor()
+            self._process_data(data)  # Process the data as needed
+            await asyncio.sleep(self.readout_frequency)
+
+
+if __name__ == "__main__":
+    service = SensorService()
+    pydase.Server(service=service).run()
+```
+
+In this example, `read_sensor_data` is a task that continuously reads data from a sensor. By decorating it with `@task(autostart=True)`, it will automatically start running when `pydase.Server(service).run()` is executed.
+
+## Task Lifecycle Control
+
+The [`@task`][pydase.task.decorator.task] decorator replaces the function with a task object that has `start()` and `stop()` methods. This means you can control the task execution directly using these methods. For instance, you can manually start or stop the task by calling `service.read_sensor_data.start()` and `service.read_sensor_data.stop()`, respectively.
+
+## Advanced Task Options
+
+The [`@task`][pydase.task.decorator.task] decorator supports several options inspired by systemd unit services, allowing fine-grained control over task behavior:
+
+- **`autostart`**: Automatically starts the task when the service initializes. Defaults to `False`.
+- **`restart_on_exception`**: Configures whether the task should restart if it exits due to an exception (other than `asyncio.CancelledError`). Defaults to `True`.
+- **`restart_sec`**: Specifies the delay (in seconds) before restarting a failed task. Defaults to `1.0`.
+- **`start_limit_interval_sec`**: Configures a time window (in seconds) for rate limiting task restarts. If the task restarts more than `start_limit_burst` times within this interval, it will no longer restart. Defaults to `None` (disabled).
+- **`start_limit_burst`**: Defines the maximum number of restarts allowed within the interval specified by `start_limit_interval_sec`. Defaults to `3`.
+- **`exit_on_failure`**: If set to `True`, the service will exit if the task fails and either `restart_on_exception` is `False` or the start rate limiting is exceeded. Defaults to `False`.
+
+### Example with Advanced Options
+
+Here is an example showcasing advanced task options:
+
+```python
+import pydase
+from pydase.task.decorator import task
+
+
+class AdvancedTaskService(pydase.DataService):
+    def __init__(self):
+        super().__init__()
+
+    @task(
+        autostart=True,
+        restart_on_exception=True,
+        restart_sec=2.0,
+        start_limit_interval_sec=10.0,
+        start_limit_burst=5,
+        exit_on_failure=True,
+    )
+    async def critical_task(self):
+        while True:
+            raise Exception("Critical failure")

+# Understanding Units
+
+`pydase` integrates with the [`pint`](https://pint.readthedocs.io/en/stable/) package to allow you to work with physical quantities within your service. This enables you to define attributes with units, making your service more expressive and ensuring consistency in the handling of physical quantities.
+
+You can define quantities in your `pydase.DataService` subclass using the `pydase.units` module.
+Here's an example:
+
+```python
+from typing import Any
+
+import pydase
+import pydase.units as u
+
+
+class ServiceClass(pydase.DataService):
+    voltage = 1.0 * u.units.V
+    _current: u.Quantity = 1.0 * u.units.mA
+
+    @property
+    def current(self) -> u.Quantity:
+        return self._current
+
+    @current.setter
+    def current(self, value: u.Quantity) -> None:
+        self._current = value
+
+
+if __name__ == "__main__":
+    service = ServiceClass()
+
+    service.voltage = 10.0 * u.units.V
+    service.current = 1.5 * u.units.mA
+
+    pydase.Server(service=service).run()
+```
+
+In the frontend, quantities are rendered as floats, with the unit displayed as additional text. This allows you to maintain a clear and consistent representation of physical quantities across both the backend and frontend of your service.
+![Web interface with rendered units](../images/Units_App.png)
+
+Should you need to access the magnitude or the unit of a quantity, you can use the `.m` attribute or the `.u` attribute of the variable, respectively. For example, this could be necessary to set the periodicity of a task:
+
+```python
+import asyncio
+import pydase
+import pydase.units as u
+
+
+class ServiceClass(pydase.DataService):
+    readout_wait_time = 1.0 * u.units.ms
+
+    async def read_sensor_data(self):
+        while True:
+            print("Reading out sensor ...")
+            await asyncio.sleep(self.readout_wait_time.to("s").m)
+
+
+if __name__ == "__main__":
+    service = ServiceClass()
+
+    pydase.Server(service=service).run()
+```
+
+For more information about what you can do with the units, please consult the documentation of [`pint`](https://pint.readthedocs.io/en/stable/).

+# Using `validate_set` to Validate Property Setters
+
+The `validate_set` decorator ensures that a property setter reads back the set value using the property getter and checks it against the desired value.
+This decorator can be used to validate that a parameter has been correctly set on a device within a specified precision and timeout.
+
+The decorator takes two keyword arguments: `timeout` and `precision`. The `timeout` argument specifies the maximum time (in seconds) to wait for the value to be within the precision boundary.
+If the value is not within the precision boundary after this time, an exception is raised.
+The `precision` argument defines the acceptable deviation from the desired value.
+If `precision` is `None`, the value must be exact.
+For example, if `precision` is set to `1e-5`, the value read from the device must be within ±0.00001 of the desired value.
+
+Here’s how to use the `validate_set` decorator in a `DataService` class:
+
+```python
+import pydase
+from pydase.observer_pattern.observable.decorators import validate_set
+
+
+class Service(pydase.DataService):
+    def __init__(self) -> None:

+# Deploying Services Behind a Reverse Proxy
+
+In some environments, you may need to deploy your services behind a reverse proxy. Typically, this involves adding a CNAME record for your service that points to the reverse proxy in your DNS server. The proxy then routes requests to the `pydase` backend on the appropriate web server port.
+
+However, in scenarios where you don’t control the DNS server, or where adding new CNAME records is time-consuming, `pydase` supports **service multiplexing** using a path prefix. This means multiple services can be hosted on a single CNAME (e.g., `services.example.com`), with each service accessible through a unique path such as `services.example.com/my-service`.
+
+To ensure seamless operation, the reverse proxy must strip the path prefix (e.g., `/my-service`) from the request URL and forward it as the `X-Forwarded-Prefix` header. `pydase` then uses this header to dynamically adjust the frontend paths, ensuring all resources are correctly located.
+
+## Example Deployment with Traefik
+
+Below is an example setup using [Traefik](https://doc.traefik.io/traefik/), a widely-used reverse proxy. This configuration demonstrates how to forward requests for a `pydase` service using a path prefix.
+
+### 1. Reverse Proxy Configuration
+
+Save the following configuration to a file (e.g., `/etc/traefik/dynamic_conf/my-service-config.yml`):
+
+```yaml
+http:
+  routers:
+    my-service-route:
+      rule: PathPrefix(`/my-service`)
+      entryPoints:
+        - web
+      service: my-service
+      middlewares:
+        - strip-prefix
+  services:
+    my-service:
+      loadBalancer:
+        servers:
+          - url: http://127.0.0.1:8001
+  middlewares:
+    strip-prefix:
+      stripprefix:
+        prefixes: /my-service
+```
+
+This configuration:
+
+- Routes requests with the path prefix `/my-service` to the `pydase` backend.
+- Strips the prefix (`/my-service`) from the request URL using the `stripprefix` middleware.
+- Forwards the stripped prefix as the `X-Forwarded-Prefix` header.
+
+### 2. Static Configuration for Traefik
+
+Ensure Traefik is set up to use the dynamic configuration. Add this to your Traefik static configuration (e.g., `/etc/traefik/traefik.yml`):
+
+```yaml
+providers:
+  file:
+    filename: /etc/traefik/dynamic_conf/my-service-config.yml
+entrypoints:
+  web:
+    address: ":80"
+```
+
+### 3. Accessing the Service
+
+Once configured, your `pydase` service will be accessible at `http://services.example.com/my-service`. The path prefix will be handled transparently by `pydase`, so you don’t need to make any changes to your application code or frontend resources.

+# Connecting Through a SOCKS5 Proxy
+
+If your target service is only reachable via an SSH gateway or resides behind a 
+firewall, you can route your [`pydase.Client`][pydase.Client] connection through a local
+SOCKS5 proxy. This is particularly useful in network environments where direct access to
+the service is not possible.
+
+## Setting Up a SOCKS5 Proxy
+
+You can create a local [SOCKS5 proxy](https://en.wikipedia.org/wiki/SOCKS) using SSH's
+`-D` option:
+
+```bash
+ssh -D 2222 user@gateway.example.com
+```
+
+This command sets up a SOCKS5 proxy on `localhost:2222`, securely forwarding traffic
+over the SSH connection.
+
+## Using the Proxy in Your Python Client
+
+Once the proxy is running, configure the [`pydase.Client`][pydase.Client] to route 
+traffic through it using the `proxy_url` parameter:
+
+```python
+import pydase
+
+client = pydase.Client(
+    url="ws://target-service:8001",
+    proxy_url="socks5://localhost:2222"
+).proxy
+```
+
+* You can also use this setup with `wss://` URLs for encrypted WebSocket connections.
+
+## Installing Required Dependencies
+
+To use this feature, you must install the optional `socks` dependency group, which 
+includes [`aiohttp_socks`](https://pypi.org/project/aiohttp-socks/):

+# Auto-generated Frontend
+
+`pydase` automatically generates a frontend interface based on your service definition, representing the current state and controls of the service.
+It simplifies the process of visualization and control of the data and devices managed by your `pydase` service, making it accessible to both developers and end-users.
+
+Through the integration of Socket.IO, the frontend provides real-time updates, reflecting changes as they occur and allowing for immediate interaction with the backend.
+
+
+## Accessing the Frontend
+
+You can access the auto-generated frontend by navigating to the hostname of the device the service is hosted on, followed by the exposed port:
+
+```
+http://<hostname>:<port>/
+```
+
+The frontend uses a component-based approach, representing various data types and control mechanisms as distinct UI components. For more information about this, please refer to [Components Guide](../Components.md).
+
+## Customization Options
+
+`pydase` allows you to enhance the user experience by customizing the web interface's appearance through
+
+1. a custom CSS file, and
+2. a custom favicon image, and
+3. tailoring the frontend component layout and display style.
+
+For more advanced customization, you can provide a completely custom frontend source.
+
+### Custom CSS Styling
+
+You can apply your own styles globally across the web interface by passing a custom CSS file to the server during initialization.
+Here's how you can use this feature:
+
+1. Prepare your custom CSS file with the desired styles.
+
+2. When initializing your server, use the `css` parameter of the `Server` class to specify the path to your custom CSS file.
+
+```python
+from pydase import Server, DataService
+
+
+class MyService(DataService):
+    # ... your service definition ...
+
+
+if __name__ == "__main__":
+    service = MyService()
+    server = Server(service, css="path/to/your/custom.css").run()
+```
+
+This will apply the styles defined in `custom.css` to the web interface, allowing you to maintain branding consistency or improve visual accessibility.
+
+Please ensure that the CSS file path is accessible from the server's running location. Relative or absolute paths can be used depending on your setup.
+
+
+### Custom favicon image
+
+You can customize the favicon displayed in the browser tab by providing your own favicon image file during the server initialization.
+
+Here's how you can use this feature:
+
+1. Prepare your custom favicon image (e.g. a `.png` file).
+2. Pass the path to your favicon file as the `favicon_path` argument when initializing the `Server` class.
+
+Here’s an example:
+
+```python
+import pydase
+
+
+class MyService(pydase.DataService):
+    # ... your service definition ...
+
+
+if __name__ == "__main__":
+    service = MyService()
+    pydase.Server(service, favicon_path="./my/local/my-favicon.png").run()
+```
+
+This will serve the specified image instead of the default `pydase` logo.
+
+
+### Tailoring Frontend Component Layout
+
+You can customize the display names, visibility, and order of components via the `web_settings.json` file.
+Each key in the file corresponds to the full access path of public attributes, properties, and methods of the exposed service, using dot-notation.
+
+- **Custom Display Names**: Modify the `"displayName"` value in the file to change how each component appears in the frontend.
+- **Control Component Visibility**: Utilize the `"display"` key-value pair to control whether a component is rendered in the frontend. Set the value to `true` to make the component visible or `false` to hide it.
+- **Adjustable Component Order**: The `"displayOrder"` values determine the order of components. Alter these values to rearrange the components as desired. The value defaults to [`Number.MAX_SAFE_INTEGER`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/MAX_SAFE_INTEGER).
+
+The `web_settings.json` file will be stored in the directory specified by the `SERVICE_CONFIG_DIR` environment variable. You can generate a `web_settings.json` file by setting the `GENERATE_WEB_SETTINGS` to `True`. For more information, see the [configuration section](../Configuration.md).
+
+For example, styling the following service 
+
+```python
+import pydase
+
+
+class Device(pydase.DataService):
+    name = "My Device"
+    temperature = 1.0
+    power = 1
+
+
+class Service(pydase.DataService):
+    device = Device()
+    state = "RUNNING"
+
+
+if __name__ == "__main__":
+    pydase.Server(Service()).run()
+```
+
+with the following `web_settings.json`
+
+```json
+{
+    "device": {
+        "displayName": "My Device",
+        "displayOrder": 1
+    },
+    "device.name": {
+        "display": false
+    },
+    "device.power": {
+        "displayName": "Power",
+        "displayOrder": 1
+    },
+    "device.temperature": {
+      "displayName": "Temperature",
+      "displayOrder": 0
+    },
+    "state": {
+        "displayOrder": 0
+    }
+}
+```
+
+looks like this:
+
+![Tailoring frontend component layout](../../images/Tailoring_frontend_component_layout.png)
+
+### Specifying a Custom Frontend Source
+
+To further customize your web interface, you can provide a custom frontend source.
+By specifying the `frontend_src` parameter when initializing the server, you can host a tailored frontend application:
+
+```python
+from pathlib import Path
+
+import pydase
+
+
+class MyService(pydase.DataService):
+    # Service definition
+
+
+if __name__ == "__main__":
+    service = MyService()
+    pydase.Server(
+        service,
+        frontend_src=Path("path/to/your/frontend/directory"),
+    ).run()
+```
+
+`pydase` expects a directory structured as follows:
+
+```bash  title="Frontend directory structure"
+<your_frontend_directory>
+├── assets
+│   └── ...
+└── index.html
+```
+
+Any CSS, js, image or other files need to be put into the assets folder for the web server to be able to provide access to it.
+
+#### Example: Custom React Frontend
+
+You can use vite to generate a react app template:
+
+```bash
+npm create vite@latest my-react-app -- --template react
+```
+
+*TODO: Add some useful information here...*
+
+To deploy the custom react frontend, build it with
+
+```bash
+npm run build
+```
+
+and pass the relative path of the output directory to the `frontend_src` parameter of the `pydase.Server`.
+
+**Note** that you have to make sure that all the generated files (except the `index.html`) are in the `assets` folder. In the react app, you can achieve this by not using the `public` folder, but instead using e.g. `src/assets`.

+print(client_proxy.voltage)  # Expected output: 5.0
+```
+
+This example shows how to set and retrieve the `voltage` attribute through the client proxy.
+The proxy acts as a local representation of the remote service, enabling intuitive interaction.
+
+The proxy class automatically synchronizes with the server's attributes and methods, keeping itself up-to-date with any changes. This dynamic synchronization essentially mirrors the server's API, making it feel like you're working with a local object.
+
+### Accessing Services Behind Firewalls or SSH Gateways
+
+If your service is only reachable through a private network or SSH gateway, you can route your connection through a local SOCKS5 proxy using the `proxy_url` parameter.
+
+See [Connecting Through a SOCKS5 Proxy](../advanced/SOCKS-Proxy.md) for details.
+
+## Context Manager Support
+
+You can also use the client within a context manager, which automatically handles connection management (i.e., opening and closing the connection):
+
+```python
+import pydase
+
+
+with pydase.Client(url="ws://localhost:8001") as client:
+    client.proxy.my_method()
+```
+
+Using the context manager ensures that connections are cleanly closed once the block of code finishes executing.
+
+## Tab Completion Support
+
+In interactive environments like Python interpreters or Jupyter notebooks, the proxy supports tab completion. This allows users to explore available methods and attributes.
+
+## Integrating the Client into Another Service
+
+You can integrate a `pydase` client proxy within another service. Here's an example of how to set this up:
+
+```python
+import pydase
+
+class MyService(pydase.DataService):
+    proxy = pydase.Client(
+        url="ws://<ip_addr>:<service_port>",
+        block_until_connected=False,
+        client_id="my_pydase_client_id",  # optional, defaults to system hostname
+    ).proxy
+
+    # For SSL-encrypted services, use the wss protocol
+    # proxy = pydase.Client(
+    #     url="wss://your-domain.ch",
+    #     block_until_connected=False,
+    #     client_id="my_pydase_client_id",
+    # ).proxy
+
+if __name__ == "__main__":
+    service = MyService()
+    # Create a server that exposes this service
+    server = pydase.Server(service, web_port=8002).run()
+```
+
+In this example:
+- The `MyService` class has a `proxy` attribute that connects to a `pydase` service at `<ip_addr>:<service_port>`.
+- By setting `block_until_connected=False`, the service can start without waiting for the connection to succeed.
+- The `client_id` is optional. If not specified, it defaults to the system hostname, which will be sent in the `X-Client-Id` HTTP header for logging or authentication on the server side.
+
+## Custom `socketio.AsyncClient` Connection Parameters
+
+You can configure advanced connection options by passing arguments to the underlying [`AsyncClient`][socketio.AsyncClient] via `sio_client_kwargs`. For example:
+
+```python
+client = pydase.Client(
+    url="ws://localhost:8001",
+    sio_client_kwargs={
+        "reconnection_attempts": 3,
+        "reconnection_delay": 2,
+        "reconnection_delay_max": 10,
+    }
+).proxy
+```
+
+In this setup, the client will attempt to reconnect three times, with an initial delay of 2 seconds (each successive attempt doubles this delay) and a maximum delay of 10 seconds between attempts.

+# RESTful API
+
+The `pydase` RESTful API allows for standard HTTP-based interactions and provides access to various functionalities through specific routes. This is particularly useful for integrating `pydase` services with other applications or for scripting and automation.
+
+For example, you can get a value like this:
+
+```python
+import json
+
+import requests
+
+response = requests.get(
+    "http://<hostname>:<port>/api/v1/get_value?access_path=<full_access_path>"
+)
+serialized_value = json.loads(response.text)
+```
+
+To help developers understand and utilize the API, we provide an OpenAPI specification. This specification describes the available endpoints and corresponding request/response formats.

-# Getting Started with Create React App
+# React + TypeScript + Vite
 
-This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
 
-## Available Scripts
+Currently, two official plugins are available:
 
-In the project directory, you can run:
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react/README.md) uses [Babel](https://babeljs.io/) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
 
-### `npm start`
+## Expanding the ESLint configuration
 
-Runs the app in the development mode.\
-Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
+If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:
 
-The page will reload when you make changes.\
-You may also see any lint errors in the console.
+- Configure the top-level `parserOptions` property like this:
 
-### `npm test`
+```js
+export default {
+  // other rules...
+  parserOptions: {
+    ecmaVersion: 'latest',
+    sourceType: 'module',
+    project: ['./tsconfig.json', './tsconfig.node.json'],
+    tsconfigRootDir: __dirname,
+  },
+}
+```
 
-Launches the test runner in the interactive watch mode.\
-See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
-
-### `npm run build`
-
-Builds the app for production to the `build` folder.\
-It correctly bundles React in production mode and optimizes the build for the best performance.
-
-The build is minified and the filenames include the hashes.\
-Your app is ready to be deployed!
-
-See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
-
-### `npm run eject`
-
-**Note: this is a one-way operation. Once you `eject`, you can't go back!**
-
-If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
-
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
-
-You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
-
-## Learn More
-
-You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).

+- Replace `plugin:@typescript-eslint/recommended` to `plugin:@typescript-eslint/recommended-type-checked` or `plugin:@typescript-eslint/strict-type-checked`
+- Optionally add `plugin:@typescript-eslint/stylistic-type-checked`
+- Install [eslint-plugin-react](https://github.com/jsx-eslint/eslint-plugin-react) and add `plugin:react/recommended` & `plugin:react/jsx-runtime` to the `extends` list

-
     Args:
-        hostname (str):
-            Hostname of the exposed service this client attempts to connect to.
-            Default is "localhost".
-        port (int):
-            Port of the exposed service this client attempts to connect on.
-            Default is 8001.
-        block_until_connected (bool):
-            If set to True, the constructor will block until the connection to the
-            service has been established. This is useful for ensuring the client is
-            ready to use immediately after instantiation. Default is True.
+        url: The URL of the pydase Socket.IO server. This should always contain the
+            protocol (e.g., `ws` or `wss`) and the hostname, and can optionally include
+            a path prefix (e.g., `ws://localhost:8001/service`).
+        block_until_connected: If set to True, the constructor will block until the
+            connection to the service has been established. This is useful for ensuring
+            the client is ready to use immediately after instantiation. Default is True.
+        sio_client_kwargs: Additional keyword arguments passed to the underlying
+            [`AsyncClient`][socketio.AsyncClient]. This allows fine-tuning of the
+            client's behaviour (e.g., reconnection attempts or reconnection delay).
+        client_id: An optional client identifier. This ID is sent to the server as the
+            `X-Client-Id` HTTP header. It can be used for logging or authentication
+            purposes on the server side. If not provided, it defaults to the hostname
+            of the machine running the client.
+        proxy_url: An optional proxy URL to route the connection through. This is useful
+            if the service is only reachable via an SSH tunnel or behind a firewall
+            (e.g., `socks5://localhost:2222`).
+
+    Example:
+        Connect to a service directly:
+
+        ```python
+        client = pydase.Client(url="ws://localhost:8001")
+        ```
+

+
+        ```python
+        client = pydase.Client(url="wss://my-service.example.com")
+        ```
+
+        Connect using a SOCKS5 proxy (e.g., through an SSH tunnel):
+
+        ```bash
+        ssh -D 2222 user@gateway.example.com
+        ```

+    and to serve the current state to newly connected clients. Internally, it creates a
+    [`DataServiceCache`][pydase.data_service.data_service_cache.DataServiceCache]
+    instance to track the state of public attributes and properties.
 
-    While the StateManager ensures that the cached state is as up-to-date as possible,
-    it does not autonomously update complex properties of the DataService. Such
-    properties must be updated programmatically, for instance, by invoking specific
-    tasks or methods that trigger the necessary operations to refresh their state.
+    The StateManager also handles state persistence: it can load a previously saved
+    state from disk at startup and periodically autosave the current state to a file
+    during runtime.
 
-    The cached state maintained by the StateManager is particularly useful for web
-    clients that connect to the system and need immediate access to the current state of
-    the DataService. By avoiding direct and potentially costly property accesses, the
-    StateManager provides a snapshot of the DataService's state that is sufficiently
-    accurate for initial rendering and interaction.
-
-    Attributes:
-        cache (dict[str, Any]):
-            A dictionary cache of the DataService's state.
-        filename (str):
-            The file name used for storing the DataService's state.
-        service (DataService):
-            The DataService instance whose state is being managed.
+    Args:
+        service: The DataService instance whose state is being managed.
+        filename: The file name used for loading and storing the DataService's state.
+            If provided, the state is loaded from this file at startup and saved to it
+            on shutdown or at regular intervals.
+        autosave_interval: Interval in seconds between automatic state save events.
+            If set to `None`, automatic saving is disabled.
 
     Note:
-        The StateManager's cache updates are triggered by notifications and do not
-        include autonomous updates of complex DataService properties, which must be
-        managed programmatically. The cache serves the purpose of providing immediate
-        state information to web clients, reflecting the state after the last property
-        update.
+        The StateManager does not autonomously poll hardware state. It relies on the
+        service to perform such updates. The cache maintained by
+        [`DataServiceCache`][pydase.data_service.data_service_cache.DataServiceCache]
+        reflects the last known state as notified by the `DataServiceObserver`, and is
+        used by the web interface to provide fast and accurate state rendering for
+        connected clients.

-    """
-    The TaskManager class is a utility designed to manage asynchronous tasks. It
-    provides functionality for starting, stopping, and tracking these tasks. The class
-    is primarily used by the DataService class to manage its tasks.
-
-    A task in TaskManager is any asynchronous function. To add a task, you simply need
-    to define an async function within your class that extends TaskManager. For example:
-
-    ```python
-    class MyService(DataService):
-        async def my_task(self):
-            # Your task implementation here
-            pass
-    ```
-
-    With the above definition, TaskManager automatically creates `start_my_task` and
-    `stop_my_task` methods that can be used to control the task.
-
-    TaskManager also supports auto-starting tasks. If there are tasks that should start
-    running as soon as an instance of your class is created, you can define them in
-    `self._autostart_tasks` in your class constructor (__init__ method). Here's how:
-
-    ```python
-    class MyService(DataService):
-        def __init__(self):
-            self._autostart_tasks = {
-                "my_task": (*args)  # Replace with actual arguments
-            }
-            self.wait_time = 1
-            super().__init__()
-
-        async def my_task(self, *args):
-            while True:
-                # Your task implementation here
-                await asyncio.sleep(self.wait_time)
-    ```
-
-    In the above example, `my_task` will start running as soon as
-    `_start_autostart_tasks` is called which is done when the DataService instance is
-    passed to the `pydase.Server` class.
-
-    The responsibilities of the TaskManager class are:
-
-    - Track all running tasks: Keeps track of all the tasks that are currently running.
-    This allows for monitoring of task statuses and for making sure tasks do not
-    overlap.
-    - Provide the ability to start and stop tasks: Automatically creates methods to
-    start and stop each task.
-    - Emit notifications when the status of a task changes: Has a built-in mechanism for
-    emitting notifications when a task starts or stops. This is used to update the user
-    interfaces, but can also be used to write logs, etc.
