Bootstrap 4 Glyphicons not showing on Angular 4 project
I'm working on an Angular 4 Project using Bootstrap 4 with Sass, and I want to use the glyphicons but when I use the following code:
<button class="btn btn-sm btn-primary"><span class="glyphicon glyphicon-thumbs-up"></span>Like</button>
For example, when making a "like" button, the icon doesn't show.
I configured the project to compile the SCSS stylesheets with the ng-serve command, my angular-cli.json looks like this:
{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"project": {
"name": "front-end-informatorio"
},
"apps": [
{
"root": "src",
"outDir": "dist",
"assets": [
"assets",
"favicon.ico"
],
"index": "index.html",
"main": "main.ts",
"polyfills": "polyfills.ts",
"test": "test.ts",
"tsconfig": "tsconfig.app.json",
"testTsconfig": "tsconfig.spec.json",
"prefix": "app",
"styles": [
"../node_modules/bootstrap/scss/bootstrap.scss",
"../node_modules/bootstrap/scss/main.scss"
],
"scripts": [],
"environmentSource": "environments/environment.ts",
"environments": {
"dev": "environments/environment.ts",
"prod": "environments/environment.prod.ts"
}
}
],
"e2e": {
"protractor": {
"config": "./protractor.conf.js"
}
},
"lint": [
{
"project": "src/tsconfig.app.json",
"exclude": "**/node_modules/**"
},
{
"project": "src/tsconfig.spec.json",
"exclude": "**/node_modules/**"
},
{
"project": "e2e/tsconfig.e2e.json",
"exclude": "**/node_modules/**"
}
],
"test": {
"karma": {
"config": "./karma.conf.js"
}
},
"defaults": {
"styleExt": "scss",
"component": {}
}
}
I tried linking this in my index.html:
<link data-require="[email protected]" data-semver="3.3.6" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.css"/>
It made the icons work, but also also changed the whole style of my project.
How do I achieve it without overlapping the styles?
Answer
Bootstrap 4 dropped Glyphicons support. (see: https://getbootstrap.com/docs/4.0/migration/#components)
This means that you'll need to use some other icon font, like Font Awesome.
Quick start for Font Awesome
- Grab the script from the get started page
- Paste it in your
<head> - Start using! Search for the icons on FontAwesome.com
- Explore the docs to unleash the full potential of Font Awesome!
Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Bootstrap + Font Awesome</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css">
<script defer src="https://use.fontawesome.com/releases/v5.0.8/js/all.js"></script>
</head>
<body>
<div class="container">
<!-- display 4 class makes the font size increase -->
<h1 class="display-4"><i class="fab fa-stack-overflow"></i></h1>
<p>That was easy! <i class="far fa-thumbs-up"></i></p>
<button type="button" class="btn btn-primary">Works also with buttons! <i class="fas fa-link"></i></button>
</div>
</body>

The Font Awesome team is working on an Angular Font Awesome component. It is right now in pre-release, but you can find it here.
