Why I Add Commitizen and commit-and-tag-version to Every JavaScript Project

Versioning and changelogs are two things I don’t want to think about while shipping code.

But ignoring them always comes back later… Wusually when I need to cut a release quickly or understand what actually changed.

So I stopped leaving it as a “later” problem.

Now, every time I start a JavaScript project, I install two things immediately:

• Commitizen
• commit-and-tag-version

That’s it. No complex setup, no over-engineering.

A Small Change That Compounds

Commitizen standardizes how I write commits using conventional commits. Instead of guessing or writing inconsistent messages, I follow a simple prompt.

Over time, this builds a commit history that’s actually useful:

• feat: → new functionality
• fix: → bug fixes
• chore: → maintenance
• BREAKING CHANGE: → clearly marked

This structure doesn’t feel important at first, but it becomes incredibly valuable when the project grows.

Automating the Boring Parts

This is where commit-and-tag-version comes in.

It reads your commit history and takes care of:

• Semantic version bumps (major, minor, patch)
• Git tagging
• Changelog generation

There’s no manual decision-making. The version reflects the actual work that’s been done.

Where This Actually Pays Off

The benefit isn’t during development—it shows up when it’s time to release.

There’s no need to:

• Figure out what version to use
• Manually write a changelog
• Dig through commits to understand changes

Everything is already structured and ready to go.

It also makes the repository easier to navigate for anyone else. The history tells a clear story without extra explanation.

Why I Do This From Day One

This setup doesn’t add complexity. It removes repeated decisions.

It turns versioning into something that happens naturally as you work, instead of something you deal with at the end.

That’s why I add it at the start of every project… not when things get messy.

Quick Setup

Install dependencies:

npm install --save-dev commitizen commit-and-tag-version

Initialize Commitizen:

npx commitizen init cz-conventional-changelog --save-dev --save-exact

Update your package.json:

{
  "scripts": {
    "commit": "cz",
    "release": "commit-and-tag-version"
  }
}

Usage:

• npm run commit → structured commits
• npm run release → version bump, tag, and changelog

You don’t need a complicated release workflow to stay organized.

You just need your commit history to carry more meaning.
