Stylus
JetBrains Rider lets you translate your Stylus code into CSS on the fly.
Before you start
Make sure you have Node.js on your computer.
Make sure the File Watchers and Stylus required plugins are enabled on the Settings/Preferences | Plugins page, tab Installed, see Managing plugins for details.
Installing Stylus
In the embedded Terminal (Alt+F12), type:
npm install --global stylusLearn more from the Stylus official website.
You can also install the stylus package on the Node.js and NPM page as described in npm, pnpm, and Yarn.
Compiling the Stylus code
To compile your code automatically, you need to configure a Stylus File Watcher which will track changes to your files and run compiler.
When you open a file, JetBrains Rider checks whether an applicable File Watcher is available in the current project. If such File Watcher is configured but disabled, JetBrains Rider displays a popup 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, JetBrains Rider starts the compiler 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 JetBrains Rider (upon frame deactivation).
JetBrains Rider 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 field of the New Watcher dialog. However, in the Project Tree, they are shown under the source file which is now displayed as a node.
