Prettier is a tool to format .js, .ts, .css, .less, .scss, .vue, and .json code. With CLion, you can format 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 computer.
Before you start
Make sure you have Node.js on your computer.
Install and enable the Prettier repository plugin on the Plugins page as described in Plugins.
To install Prettier
In the embedded Terminal (Alt+F12), 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 CLion
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 and configure a new one.
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 press N/A or select Reformat with Prettier from the context menu.
Alternatively, press Ctrl+Shift+A and select Reformat with Prettier from the Find Action list.
CLion can apply the key code style rules from the Prettier's configuration to the CLion 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.
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.
