Automating npm Package Releases

semantic-release is a tool which fully automates the process of releasing your code to the world. It determines the next version based on the commit messages (e.g. fix, feat) giving you full control over the next version but still automating the release process. This short article shows how to setup semantic-release for an npm package using GitHub Actions.

First, create a GitHub Action which calls npx semantic-release (or yarn semantic-release if you use Yarn). This should be run after any other pre-release steps such as npm run build and npm test.

name: Release
on: [push]
    runs-on: ubuntu-latest
      - uses: actions/checkout@v3
      - run: npm ci
      - run: npx semantic-release
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

Next, update your package changelog to indicate that change notes can be viewed on the releases tab.
# Changelog

The changelog is automatically updated using
You can see it on the [releases page](../../releases).

Finally, update the version in your package.json to something that indicates your package is versioned using semantic release.

  "version": "0.0.0-semantically-released"

That’s it! Your package is now being automatically released via semantic-release!
