-# upload-artifact
+# Upload-Artifact v2
 
-This uploads artifacts from your workflow.
+This uploads artifacts from your workflow allowing you to share data between jobs and store data once a workflow is complete.
 
 See also [download-artifact](https://github.com/actions/download-artifact).
 
+# What's new
+
+- Easier upload 
+  - Specify a wildcard pattern
+  - Specify an individual file
+  - Specify a directory (previously you were limited to only this option)
+  - Multi path upload
+    - Use a combination of individual files, wildcards or directories
+    - Support for excluding certain files
+- Upload an artifact without providing a name
+- Fix for artifact uploads sometimes not working with containers
+- Proxy support out of the box
+- Port entire action to typescript from a runner plugin so it is easier to collaborate and accept contributions
+
+Refer [here](https://github.com/actions/upload-artifact/tree/releases/v1) for the previous version
+
 # Usage
 
 See [action.yml](action.yml)
 
-Basic:
+### Upload an Individual File
 ```yaml
 steps:
-- uses: actions/checkout@v1
+- uses: actions/checkout@v2
 
 - run: mkdir -p path/to/artifact
 
 - run: echo hello > path/to/artifact/world.txt
 
-- uses: actions/upload-artifact@v1
+- uses: actions/upload-artifact@v2
   with:
     name: my-artifact
-    path: path/to/artifact
+    path: path/to/artifact/world.txt
 ```
 
+### Upload an Entire Directory
+
+```yaml
+- uses: actions/upload-artifact@v2
+  with:
+    name: my-artifact
+    path: path/to/artifact/ # or path/to/artifact
+```
+
+### Upload using a Wildcard Pattern
+```yaml
+- uses: actions/upload-artifact@v2
+  with:
+    name: my-artifact
+    path: path/**/[abc]rtifac?/*
+```
+
+### Upload using Multiple Paths and Exclusions
+```yaml
+- uses: actions/upload-artifact@v2
+  with:
+    name: my-artifact
+    path: |
+      path/output/bin/
+      path/output/test-results
+      !path/**/*.tmp
+```
+
+For supported wildcards along with behavior and documentation, see [@actions/glob](https://github.com/actions/toolkit/tree/master/packages/glob) which is used internally to search for files.
+
+If a wildcard pattern is used, the path hierarchy will be preserved after the first wildcard pattern. 
+
+```
+    path/to/*/directory/foo?.txt =>
+        ∟ path/to/some/directory/foo1.txt
+        ∟ path/to/some/directory/foo2.txt
+        ∟ path/to/other/directory/foo1.txt
+
+    would be flattened and uploaded as =>
+        ∟ some/directory/foo1.txt
+        ∟ some/directory/foo2.txt
+        ∟ other/directory/foo1.txt
+```
+If multiple paths are provided as input, the least common ancestor of all the search paths will be used as the root directory of the artifact. Exclude paths do not effect the directory structure.
+
+Relative and absolute file paths are both allowed. Relative paths are rooted against the current working directory. Paths that begin with a wildcard character should be quoted to avoid being interpreted as YAML aliases.
+
+The [@actions/artifact](https://github.com/actions/toolkit/tree/master/packages/artifact) package is used internally to handle most of the logic around uploading an artifact. There is extra documentation around upload limitations and behavior in the toolkit repo that is worth checking out.
+
+### Conditional Artifact Upload
+
 To upload artifacts only when the previous step of a job failed, use [`if: failure()`](https://help.github.com/en/articles/contexts-and-expression-syntax-for-github-actions#job-status-check-functions):
 
 ```yaml
-- uses: actions/upload-artifact@v1
+- uses: actions/upload-artifact@v2
   if: failure()
   with:
     name: my-artifact
-    path: path/to/artifact
+    path: path/to/artifact/
 ```
 
+### Uploading without an artifact name
+
+You can upload an artifact without specifying a name
+```yaml
+- uses: actions/upload-artifact@v2
+  with:
+    path: path/to/artifact/world.txt
+```
+
+If not provided, `artifact` will be used as the default name which will manifest itself in the UI after upload.
+
+### Uploading to the same artifact
+
+Each artifact behaves as a file share. Uploading to the same artifact multiple times in the same workflow can overwrite and append already uploaded files
+
+```yaml
+- run: echo hi > world.txt
+- uses: actions/upload-artifact@v2
+  with:
+    path: world.txt
+
+- run: echo howdy > extra-file.txt
+- uses: actions/upload-artifact@v2
+  with:
+    path: extra-file.txt
+
+- run: echo hello > world.txt
+- uses: actions/upload-artifact@v2
+  with:
+    path: world.txt
+```
+With the following example, the available artifact (named `artifact` which is the default if no name is provided) would contain both `world.txt` (`hello`) and `extra-file.txt` (`howdy`).
+
+> **_Warning:_**  Be careful when uploading to the same artifact via multiple jobs as artifacts may become corrupted 
+
+```yaml
+    strategy:
+      matrix:
+          node-version: [8.x, 10.x, 12.x, 13.x]
+    steps:
+        - name: 'Create a file'
+          run: echo ${{ matrix.node-version }} > my_file.txt
+        - name: 'Accidently upload to the same artifact via multiple jobs'
+          uses: 'actions/upload-artifact@v2'
+          with:
+              name: my-artifact
+              path: ${{ github.workspace }}
+```
+
+In the above example, four jobs will upload four different files to the same artifact but there will only be one file available when `my-artifact` is downloaded. Each job overwrites what was previously uploaded. To ensure that jobs don't overwrite existing artifacts, use a different name per job.
+
+```yaml
+          uses: 'actions/upload-artifact@v2'
+          with:
+              name: my-artifact ${{ matrix.node-version }}
+              path: ${{ github.workspace }}
+```
+
+### Environment Variables and Tilde Expansion
+
+You can use `~` in the path input as a substitute for `$HOME`. Basic tilde expansion is supported.
+
+```yaml
+  - run: |	
+      mkdir -p ~/new/artifact
+      echo hello > ~/new/artifact/world.txt
+  - uses: actions/upload-artifact@v2
+    with:	
+      name: 'Artifacts-V2'	
+      path: '~/new/**/*'
+```
+
+Environment variables along with context expressions can also be used for input. For documentation see [context and expression syntax](https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions).
+
+```yaml
+    env:
+      name: my-artifact
+    steps:
+    - run: |	
+        mkdir -p ${{ github.workspace }}/artifact
+        echo hello > ${{ github.workspace }}/artifact/world.txt
+    - uses: actions/upload-artifact@v2
+      with:	
+        name: ${{ env.name }}-name	
+        path: ${{ github.workspace }}/artifact/**/*
+```
