Summary

Prettier is a free, open-source code formatter that parses code and prints it in a consistent style, taking line length into account. Built-in language support includes JavaScript, JSX, Angular, Vue, Flow, TypeScript, CSS, Less, SCSS, HTML, JSON, GraphQL, Markdown, YAML, LWC and MJML. Use its command-line interface with `--write` to format files or `--check` to check formatting in CI. Listed editor integrations include VS Code, Emacs, Vim, Helix, Sublime Text, JetBrains IDEs, Visual Studio and Espresso; formatting can run from an editor shortcut or when saving a file. Prettier has configuration options but keeps them limited. Plugins can add languages or formatting rules, and languages beyond its built-in set require a plugin. For ESLint, its install guide recommends `eslint-config-prettier` to disable rules that are unnecessary or may conflict. The tool supports browser and JavaScript API use as well as Linux, macOS and Windows. Enterprise support and maintenance are available through the Tidelift Subscription.

Who it is for
