Prettier is a tool to format
.json code. With WebStorm, you can format selected code fragments as well as entire files or directories using the Reformat with Prettier action. WebStorm adds this action as soon as you install Prettier as a dependency in your project or globally on your computer.
To install Prettier
Open the embedded Terminal (Alt+F12).
At the command prompt, type
npm install --save-dev --save-exact prettieror
npm install --global prettier. Learn more about installation modes from the Prettier official website.
To configure Prettier in WebStorm
On the Prettier page, that opens, specify the path to the
prettierpackage 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 press Ctrl+Shift+Alt+P or choose Reformat with Prettier on the context menu of the selection.
Alternatively, press Ctrl+Shift+A and click Reformat with Prettier in the Find Action list.
WebStorm can apply the key code style rules from the Prettier's configuration to the WebStorm Code Style settings so that generated code (e.g. 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.
