Prettier

Last modified: 08 October 2024

Prettier is a tool to format files in various languages, like TypeScript, JavaScript, CSS, HTML, JSON, and others. With IntelliJ IDEA, you can format selected code fragments as well as entire files or directories using the Reformat with Prettier action. IntelliJ IDEA adds this action as soon as you install Prettier as a dependency in your project or globally on your computer.

You can configure Prettier to reformat specific files every time such file is changed and the changes are saved automatically or manually, refer to Run Prettier automatically on save.

Also, Prettier can be set as default formatter for specific files. It will run against such files every time you reformat your code with CtrlAlt0L.

For more information, refer to Reformat code with Prettier.
