Github action to make npm (pre)releases

Prerelease

To make npm prereleases on git push to master add .github/workflows/prerelease.yml

on:
    push:
        branches:
            - master

jobs:
    prerelease:
        runs-on: ubuntu-latest
        steps:
            - uses: actions/checkout@v1
            - name: Make prerelease to npm
              uses: epeli/npm-release@v1
              with:
                  type: prerelease
                  token: ${{ secrets.NPM_TOKEN }}

This bumbs the patch version and makes new release with a next tag. The versions will look like 1.0.1-dev.c7f620550 where is the suffix is the git revision the release was made from.

Stable release

To make a stable npm release when a Github release is made add .github/workflows/release.yml

on:
    release:
        types: [published]

jobs:
    prerelease:
        runs-on: ubuntu-latest
        steps:
            - uses: actions/checkout@v1
            - name: Make stable release to npm
              uses: esamatti/npm-release@v2
              with:
                  type: stable
                  token: ${{ secrets.NPM_TOKEN }}

This will just do the release using the version in package.json.

To easily make a Github release with a git tag you can use np with --no-publish flag.

npx np --no-publish

Running tests and building

If you need to run build and/or tests before the release you can add a workflow step for it or just add it to the prepublishOnly script in package.json.
