Commits that follow a standard and descriptive format can be parsed programmitically to learn much about the state of the repository.

Most particularly...

• The next logical Semantic Version bump
• CHANGLOG (for Humans)

(i.e. Releases)

While many commit formats exist and you can invent your own, this project templates (and examplifies) the most popular, Conventional format.

How It Works

All tooling is provided via npm packages.

Commits are Linted

In order for any of this to be worthwhile and work, commits have to consistently follow the desired, Conventional, format. Therefore, a pre-commit hook linter in order.

package.json

{
  "devDependencies": {
    "@commitlint/cli": "^7.3.2",
    "@commitlint/config-conventional": "^7.3.1",
    "husky": "^1.3.1"
  },
  "husky": {
    "hooks": {
      "commit-msg": "commitlint -E HUSKY_GIT_PARAMS"
    }
  }
}

commitlint.config.js

module.exports = {extends: ['@commitlint/config-conventional']};

Commits are Assisted

Writing repetitive, descriptive commits is necessary for honoring the standard, Conventional, format. However, writing (let alone, learning) them completely manually is tiresome and not necessary.

Instead of using git commit, use...

> npm run cm

package.json

{
  "scripts": {
    "cm": "git-cz"
  },
  "devDependencies": {
    "commitizen": "^3.0.5",
    "cz-conventional-changelog": "^2.1.0",
  },
  "config": {
    "commitizen": {
      "path": "./node_modules/cz-conventional-changelog"
    }
  }
}

Versioning is Scripted

Once you have a Conventional commit log, you are ready to enjoy auto-generated Changelog and Version bumps.

> npm run release

> git push --follow-tags origin master

(release only tags commits locally, so they need to bu pushed up after)

package.json

{
  "scripts": {
    "release": "standard-version"
  },
  "devDependencies": {
    "standard-version": "^4.4.0"
  }
