Font Awesome 5 and Angular 5

I'm using this in angular 8 version. It's working perfectly. Please follow this simple procedure:

1. First install it by angular cli

   npm install --save @fortawesome/fontawesome-free

2. Open angular.json and update the css file as follow

   "styles": [ "styles.css", "node_modules/@fortawesome/fontawesome-free/css/all.css"]

3. Restart your server

eg, how to add

<i class="fas fa-paper-plane"></i>

Happy coding :)

For more font awesome icons

Yes, you could import and add them all

import { fas } from '@fortawesome/free-solid-svg-icons';
import { far } from '@fortawesome/free-regular-svg-icons';

export class AppModule {
  constructor(library: FaIconLibrary) {
    library.addIconPacks(fas, far);
  }
}

However

You can also import entire icon styles. But be careful! This way of importing icons does not support tree-shaking, so all icons from the imported package will end up in the bundle.

Also, since you are using angular-fontawesome, use it:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FontAwesomeModule, FaIconLibrary } from '@fortawesome/angular-fontawesome';
import { faCoffee } from '@fortawesome/free-solid-svg-icons';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, FontAwesomeModule],
  bootstrap: [AppComponent]
})
export class AppModule {
  constructor(library: FaIconLibrary) {
    // Add an icon to the library for convenient access in other components
    library.addIcons(faCoffee);
  }
}

and in html

<!-- simple name only that assumes the default prefix -->
<fa-icon icon="coffee"></fa-icon>
<!-- ['fas', 'coffee'] is an array that indicates the [prefix, iconName] -->
<fa-icon [icon]="['fas', 'coffee']"></fa-icon>

All code taken from the official documentation

Install

npm install --save @fortawesome/fontawesome-free

and use in .angular-cli

 "styles": [
    "styles.css",
    "../node_modules/@fortawesome/fontawesome-free/css/all.css",
