Compiling Stylus to CSS
WebStorm integrates with a compiler that translates Stylus code into CSS.
Open the embedded Terminal ( ) and type
npm install --global stylus at the command prompt for global installation. Learn more from the Stylus Official website.
Creating a file watcher
WebStorm provides a common procedure and user interface for creating File Watchers of all types. The only difference is in the predefined templates you choose in each case.
- To start creating a File Watcher, open the Settings/Preferences dialog box by choosing File Watchers under the Tools node. The File Watchers page that opens, shows the list of File Watchers that are already configured in the project. for Windows and Linux or for macOS on the main menu, and then click
- Click the Add button or press Alt+Insert and choose the Stylus predefined template from the pop-up list.
- In the Program text box, specify the path to the executable file:
stylusfor macOS and Unix.
- Proceed as described on page Using File Watchers.
Compiling the code
When you open a Stylus file, WebStorm checks whether an applicable file watcher is available in the current project. If such file watcher is configured but disabled, WebStorm displays a pop-up window that informs you about the configured file watcher and suggests to enable it.
If an applicable file watcher is configured and enabled in the current project, WebStorm starts it automatically upon the event specified in the New Watcher dialog.
- If the Auto-save edited files to trigger the watcher checkbox is selected, the File Watcher is invoked as soon as any changes are made to the source code.
- If the Auto-save edited files to trigger the watcher checkbox is cleared, the File Watcher is started upon save ( , Ctrl+S) or when you move focus from WebStorm (upon frame deactivation).
WebStorm creates a separate file with the generated output. The file has the name of the source Stylus file and the extension
css. The location of the generated files is defined in the Output paths to refresh text box of the New Watcher dialog. However, in the Project Tree, they are shown under the source file which is now displayed as a node.
