CLion 2018.1 Help

Prettier

CLion integrates with the Prettier code formatter. You can reformat selected code fragments as well as entire files or directories using the Reformat with Prettier action. CLion adds this action as soon as you install Prettier as a dependency in your project or globally on your machine, Prettier is available in .js, .ts, .css, .less, .scss, .vue, and .json files.

Moreover, the key code style rules from the Prettier's configuration are applied to the CLion Code Style settings. As a result, generated code (e.g. after refactoring or quick-fix) and the code that is already processed with Prettier are formatted consistently.

Before you start

  1. Download, install, and configure Node.js as described in .
  2. Install and enable the NodeJS and Prettier repository plugins on the Plugins page as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.

To install Prettier

  • Open the embedded Terminal (View | Tool Windows | Terminal) and type npm install --save-dev --save-exact prettier or npm install --global prettier at the command prompt. Learn more about installation modes from the Prettier Official website.

To configure Prettier in CLion

  1. In the Settings/Preferences dialog (Ctrl+Alt+S), click JavaScript under Languages and Frameworks, and then click Prettier.
  2. On the Prettier page, that opens, specify the path to the prettier package and choose the Node.js interpreter to use. If you choose the Project alias, CLion will automatically use the project default interpreter from the Node interpreter field on the Node.js and NPM page.

    In most cases, CLion detects the project default interpreter and fills in the field itself. You can also choose another configured local interpreter or click browseButton and configure a new one.
