name	prettier
description	Prettier code formatter for consistent style. Use for formatting.

Prettier

Prettier ended the "Style Wars". It accepts your code and reprints it with its own rules. v3.x runs as ESM and supports plugins.

When to Use

• Always: Every project should have a formatter.
• Collaborating: Eliminates "nitpick" comments in PRs about whitespace.

Core Concepts

Opinionated

Few options. Print width, tab width, semi, quotes. That's it.

Editor Integration

"Format on Save".

Plugins

prettier-plugin-tailwindcss sorts classes automatically.

Best Practices (2025)

Do:

• Run in CI: Ensure code is formatted before merge (prettier --check .).
• Ignore generated files: Add .prettierignore.

Don't:

• Don't argue about style: Just run Prettier.
