npm-publish-action

GitHub action to automatically publish packages to npm.

Usage

Create a new .github/workflows/npm-publish.yml file:

name: npm-publish
on:
  push:
    branches:
      - master # Change this to your default branch
jobs:
  npm-publish:
    name: npm-publish
    runs-on: ubuntu-latest
    steps:
    - name: Checkout repository
      uses: actions/checkout@master
    - name: Set up Node.js
      uses: actions/setup-node@master
      with:
        node-version: 10.0.0
    - name: Publish if version has been updated
      uses: pascalgn/npm-publish-action@06e0830ea83eea10ed4a62654eeaedafb8bf50fc
      with: # All of theses inputs are optional
        tag_name: "v%s"
        tag_message: "v%s"
        commit_pattern: "^Release (\\S+)"
        workspace: "."
      env: # More info about the environment variables in the README
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} # Leave this as is, it's automatically generated
        NPM_AUTH_TOKEN: ${{ secrets.NPM_AUTH_TOKEN }} # You need to set this in your repo settings

Now, when someone changes the version in package.json to 1.2.3 and pushes a commit with the message Release 1.2.3, the npm-publish action will create a new tag v1.2.3 and publish the package to the npm registry.

Inputs

These inputs are optional: that means that if you don't enter them, default values will be used and it'll work just fine.

  • tag_name: the name pattern of the new tag
  • tag_message: the message pattern of the new tag
  • commit_pattern: pattern that the commit message needs to follow
  • workspace: custom workspace directory that contains the package.json file

Environment variables

  • GITHUB_TOKEN: this is a token that GitHub generates automatically, you only need to pass it to the action as in the example
  • NPM_AUTH_TOKEN: this is the token the action will use to authenticate to npm. You need to generate one in npm, then you can add it to your secrets (settings -> secrets) so that it can be passed to the action. DO NOT put the token directly in your workflow file.
