Sass CLI tool

Install

You will only need to run this command once, since it installs the tool globally.

$ npm install -g node-sass
  • npm is the command for the node package manager
  • install is telling npm to install a package onto your computer. This is usually into the current working directory, but can also be global
  • -g makes the install global instead of local
  • node-sass is the name of the package you want to install.

Watching a directory for changes

$ node-sass -rw scss -o css

  • node-sass runs the node version of the Sass/SCSS compiler to turn SCSS into CSS

  • -rw scss means "recursively watch the scss directory for changes". This makes the command run indefinitely, it will continue to watch for changes until you kill it with Control-C

  • -o css means "output into the css directory".
