Prettier

Prettier is a code formatter that automatically formats your code to ensure a consistent style. It works with many programming languages including JavaScript, TypeScript, CSS, HTML, JSON, Markdown, and GraphQL. The tool is opinionated, meaning it makes decisions about code formatting so developers don't have to debate style choices. It integrates directly into your workflow and can format code on save in your editor.

Prettier works by parsing your code and re-printing it with its own rules that take the maximum line length into account. What sets it apart is its minimal configuration approach - it has few options by design to prevent teams from spending time configuring style rules. It supports integration with most popular code editors including VS Code, WebStorm, Vim, and Sublime Text through extensions. Community plugins extend its capabilities to additional languages like Java, PHP, and Ruby.

This tool is particularly valuable for development teams that want to maintain consistent code style without manual effort. It saves time by automating formatting and eliminates style debates during code reviews. Both individual developers and large organizations like Facebook, React, and Dropbox use Prettier to keep their codebases clean and readable.
