Config Commitlint

This is the configuration to lint our commitmessages at flagbit. The basic format is simply using conventionalcommits, this config is only setting some more precise specifications.

This config is used by a tool named commitlint, that comes pretty handy to have a clean, readable git-history.

Conventionalcommits in general are giving us 3 important benefits:

1. our git history is clean, readable and informative
2. we can use automatic-semantic-versioning in our projects, the version to set is then generated out of the commitmessages. (type and breaking-change)
3. we can generate automated CHANGELOG files in our repositories. These are then also generated out of the commitmessages. (type and scope)

How should a good COMMTIMSG look?

fix: Don't use GITHUB_TOKEN for release-please

Because events generated by a GITHUB_TOKEN will not trigger
other workflows.

How can I use this in my project?

Create a new file named commitlint.config.js in your projects root directory, including this content:

module.exports = {
  extends: ["@flagbit/config-commitlint"],
  parserPreset: {
    parserOpts: {
      issuePrefixes: ["\\s[\\w\\d]{1,10}-"],
    },
  },
};

...add (or extend an existing) Makefile to include a lint target:

.DEFAULT_GOAL := lint
GITHUB_BASE_REF ?= master

.PHONY: lint
lint:
	commitlint -g commitlint.config.js --from=$$(git rev-parse remotes/origin/$(GITHUB_BASE_REF))

...and finally add a github-workflow to your project by placing a file named commitlint.yml to the .github/workflows/-directory in your project. If this directory is not existing, then you can simply create it. The commitlint.yml needs to include this content:

name: commitlint
on: pull_request

jobs:
  commitlint:
    name: Lint Commit Messages
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 0
      - run: |
          yarn global add @commitlint/cli @flagbit/config-commitlint 
          echo "$(yarn global bin)" >> $GITHUB_PATH
      - run: make lint

How can I use this locally?

The package holding our config is published to default npm-registry. Because most of us have set in their .npmrc to use our private registry for the namespace @flagbit, it is necessary to tell yarn/npm which registry to use. You can do like this:

yarn global add @commitlint/cli @flagbit/config-commitlint --registry https://registry.npmjs.org
