GitHub action to publish your VS Code Extension to the Open VSX Registry or the Visual Studio Marketplace.

All breaking changes of v1 are listed in the changelog

To use the GitHub Action, just reference the action in your workflow file.

The following example shows a workflow that publishes an extension to the Open VSX Registry as well as to the Visual Studio Marketplace when a new tag was created:

on:
  push:
    tags:
      - "*"

name: Deploy Extension
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
      - run: npm ci
      - name: Publish to Open VSX Registry
        uses: HaaLeo/publish-vscode-extension@v1
        with:
          pat: ${{ secrets.OPEN_VSX_TOKEN }}
      - name: Publish to Visual Studio Marketplace
        uses: HaaLeo/publish-vscode-extension@v1
        with:
          pat: ${{ secrets.VS_MARKETPLACE_TOKEN }}
          registryUrl: https://marketplace.visualstudio.com

To package the extension only once and publish the identical .vsix file to both registries one can use the following two steps instead:

- name: Publish to Open VSX Registry
  uses: HaaLeo/publish-vscode-extension@v1
  id: publishToOpenVSX
  with:
    pat: ${{ secrets.OPEN_VSX_TOKEN }}
- name: Publish to Visual Studio Marketplace
  uses: HaaLeo/publish-vscode-extension@v1
  with:
    pat: ${{ secrets.VS_MARKETPLACE_TOKEN }}
    registryUrl: https://marketplace.visualstudio.com
    extensionFile: ${{ steps.publishToOpenVSX.outputs.vsixPath }}

For a more complete and complex example one can check out the workflow of HaaLeo/vscode-timing.

To publish to the Open VSX Registry ensure that your extension's namespace was created beforehand. You need to set the pat parameter to your Open VSX access token. Further, you should ensure that you only publish an extension which is licensed. For more information regarding Open VSX' timeline and its extensions' licensing check out Brian King's blog (section "Licensing" and "Timeline").

Currently, this GitHub action allows you to publish extensions which do not state their license terms. However, this behavior is deprecated and a future release of this action will reject unlicensed extensions. Therefore, I heavily encourage you to publish an extension with a (permissive) license such as the MIT license.

In order to upload your extension to the VS Marketplace you need to set the pat option to the corresponding access token. Further, the registryUrl must be set to https://marketplace.visualstudio.com.

You can set any or all of the following input parameters:

The action exposes the following outputs:
