Watch mode automatically monitors your Sass files for changes and compiles them to CSS whenever you save, so you don’t have to run the compile command manually each time.

It saves time and effort by automatically compiling your Sass files whenever you make changes, so you can see updates in your browser immediately without extra steps.

Can watch mode handle multiple Sass files at once?

Yes, by watching a folder instead of a single file, Sass will compile all files inside that folder to CSS automatically when any file changes.

What happens if you stop the watch mode process?

Sass will stop monitoring your files, so changes you make won’t compile automatically until you start watch mode again.

Which command starts Sass watch mode for a single file?
