For version 5, you need following package @fortawesome/fontawesome. See installation using package managers.
Using npm:
npm install --save @fortawesome/fontawesome-free
Then reference either the all.css or all.js in the <head>.
<link rel="stylesheet" href="node_modules/@fortawesome/fontawesome-free/css/all.css">
Note: Make sure the path is right, depends on where you installed the package from.
OR you can import the module in your js code.
import '@fortawesome/fontawesome-free/js/all.js';
OR if you are using Sass, you can import the module in app.scss.
@import '~@fortawesome/fontawesome-free/scss/fontawesome';
@import '~@fortawesome/fontawesome-free/scss/<type>';
Note: Replace <type> with solid, brands or regular whatever type of icons you need.

npm install --save @fortawesome/free-<type>-svg-icons
npm install --save @fortawesome/angular-fontawesome
Note: Replace <type> with solid, brands or regular whatever type of icons you need.
