ltk-publish-lerna-action

Shared github action for automated package publishing in lerna monorepos

This Dockerized action is using Node v12

What it does

Checks your commit messages and

• If it detects the text BREAKING CHANGE it publishes a MAJOR version
• Otherwise it publishes a PATCH or MINOR version following the conventional commits format

Setup

1. Your project should be a lerna monorepo

2. In case you have configured an "allowBranch" in your lerna.json make sure that the action ONLY runs in that branch

3. In your action make sure to configure the env variable of PRIVATE_REPO_PAT

Example Usage

The following config assumes that

• The branch used for publishing is the main
• Only runs for the push event
• Runs only if a change in the packages folder has been made

name: Publish
on:
  push:
    branches:
      - main
    paths:
      - 'packages/**'
jobs:
  publish-lerna-packages:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout 🛎️
        uses: actions/checkout@v2.3.1
        with:
          # pulls all commits (needed for lerna / semantic release to correctly version)
          fetch-depth: "0"

      - name: Publish 🚀
        uses: LoveToKnow/ltk-publish-lerna-action@main
        env:
          PRIVATE_REPO_PAT: ${{ secrets.PRIVATE_REPO_PAT }}
