font awesome icons not showing up on ionic3 app

Question

I have implemented font awesome icons in my ionic3 app, but it does not show up. My ionic project environment details,

cli packages: (C:\Users\acer\AppData\Roaming\npm\node_modules)

    @ionic/cli-utils  : 1.19.2
    ionic (Ionic CLI) : 3.20.0

local packages:

    @ionic/app-scripts : 3.1.8
    Ionic Framework    : ionic-angular 3.9.2

System:

    Node : v8.4.0
    npm  : 5.8.0
    OS   : Windows 10

Misc:

    backend : pro

this is my intro.html file,

<ion-slides pager>
  <ion-slide style="background-color:yellow" >
      <i class="fas fa-utensils" style="font-size:120px;color:#ebebeb" aria-hidden="true"></i>
    </ion-slide>

  </ion-slides>

this is in my index.html file

 <!-- font-awesome -->
  <link href="/assets/css/font-awesome.min.css" rek="stylesheet" type="text/html">

I have already added following code, as many blog posts and SO answers suggested in my copy.config.js file

copyFontawesomeFonts: {
    src: ['{{ROOT}}/node_modules/font-awesome/fonts/**/*'],
    dest: '{{WWW}}/assets/fonts'
  },
  copyFontawesomeCss: {
    src: ['{{ROOT}}/node_modules/font-awesome/css/font-awesome.min.css'],
    dest: '{{WWW}}/assets/css'
  },

Answer 1

You have syntax error in linking stylesheet

<link href="/assets/css/font-awesome.min.css" rek="stylesheet" type="text/html">

It should be

<link href="/assets/css/font-awesome.min.css" rel="stylesheet" type="text/css">

Answer 2

If you are linking a css-stylesheet its type should always be

type="text/css"

Change it from

<!-- font-awesome -->
<link href="/assets/css/font-awesome.min.css" rek="stylesheet" type="text/html">

to

<!-- font-awesome -->
<link href="/assets/css/font-awesome.min.css" rek="stylesheet" type="text/css">

Answer 3

I have faced this issue earlier. Resolved it by loading css file from below url instead of loading from assets.
