1.- Install Node.js

To compile Sass via the command line first, we need to install node.js. The easiest way is downloading it from the official website nodejs.org open the package and follow the wizard.

2.- Initialize NPM

NPM is the Node Package Manager for JavaScript. NPM makes it easy to install and uninstall third party packages. To initialize a Sass project with NPM, open your terminal and CD (change directory) to your project's webroot folder.

npm init

Once in the correct folder, run the command npm init. You will be prompted to answer several questions about the project, after which NPM will generate a package.json file in your folder.

3.- Install Node-Sass

Node-sass is an NPM package that compiles Sass to CSS (which it does very quickly too). To install node-sass run the following command in your terminal: npm install node-sass

npm install node-sass

4.- Write Node-sass Command

Everything is ready to write a small script in order to compile Sass. Open the package.json file in a code editor. You will see something like this: In the scripts section add an scss command

"scripts": {
  "sass": "node-sass --watch scss/main.scss css/style.css"
},

5.- Run the Script

To execute our one-line script, we need to run the following command in the terminal: npm run sass

npm run sass

6.- Other Option

--source-map

"sass": "node-sass --watch scss/main.scss css/style.css --source-map css/style.css.map"
