JetBrains Rider 2019.2 Help

Prettier

Prettier is a tool to format .js, .ts, .css, .less, .scss, .vue, and .json code. With JetBrains Rider, you can format selected code fragments as well as entire files or directories using the Reformat with Prettier action. JetBrains Rider adds this action as soon as you install Prettier as a dependency in your project or globally on your computer.

Before you start

  1. Make sure you have Node.js on your computer.

  2. Install and enable the Prettier repository plugin on the Plugins page as described in Managing plugins.

To install Prettier

In the embedded Terminal (Ctrl+Alt+1), type one of the following commands:

  • npm install --save-dev --save-exact prettier
  • npm install --global prettier

Learn more about installation modes from the Prettier official website.

To configure Prettier in JetBrains Rider

  1. In the Settings/Preferences dialog (Ctrl+Alt+S), go to Languages and Frameworks | JavaScript | Prettier.

  2. On the Prettier page, that opens, specify the path to the prettier package and choose the Node.js interpreter to use. This can be a local Node.js interpreter or a Node.js on Windows Subsystem for Linux.

To reformat code with Prettier

  • Select the code fragment to reformat in the editor or select a file or a folder in the Project tool window and select Reformat with Prettier from the context menu.

  • Alternatively, press Ctrl+Shift+A and select Reformat with Prettier from the Find Action list.

JetBrains Rider can apply the key code style rules from the Prettier's configuration to the JetBrains Rider Code Style settings so that generated code (for example, after refactoring or quick-fix) and the code that is already processed with Prettier are formatted consistently.

To apply Prettier code style rules

  • In the project where Prettier is enabled, open package.json and click Yes in the pane at the top of the tab.

    Pane above package.json: apply Prettier code style

  • To re-apply the Prettier code style (after you've clicked No in the pane or modified the code style), press Ctrl+Shift+A and select Apply Prettier Code Style Rules from the Find Action list.
