Bootstrap Glyphicons not displaying in angular2

Bootstrap Glyphicons not displaying in angular2

I am trying to use bootstrap glyphicons in my angular2 app. I have installed bootstrap using the command npm install bootstrap –save
My code snippet is

I have included bootstrap in my styleUrls-
styleUrls: [‘node_modules/bootstrap/dist/css/bootstrap.min.css’, ‘app/home.component.css’]
The glyphicon appears as shown-


Solution 1:

Boostrap 4 does not support Glyphicons anymore, you can use Font Awesome instead:

npm install --save font-awesome

and add the css File to your .angular-cli.json

"apps": [
             "styles": [


Replace CSS class with the Font Awesome classes:

<i class="navbar-toggler-icon fa fa-bars"> </i>

recompile app: ng serve

Solution 2:

You have to import

<link data-require="bootstrap-css@3.3.6" data-semver="3.3.6" rel="stylesheet" href="" />

to your index.html

Solution 3:

I installed bootstrap3 as npm install bootstrap@3 and it started working

just need to add in angular-cli.json:-

   "styles": [

Solution 4:

There is angular-cli-build.js file of root of the project if your application has been scaffold by angular-cli (using ‘ng init’ or ‘ng new’).

angular-cli-build.js instructs build of the project (using ‘ng serve’ or ‘ng build’) to place 3rd-party libraries into vendor folder.

There is fonts folder, in bootstrap distribution folder, holding glyphicons files. Those bootstrap files needs to be placed into vendor folder too.


// Angular-CLI build configuration
// This file lists all the node_modules files that will be used in a build
// Also see

/* global require, module */

var Angular2App = require('angular-cli/lib/broccoli/angular2-app');

module.exports = function(defaults) {
  return new Angular2App(defaults, {
    vendorNpmFiles: [

For completeness, setup process for bootstrap was in those few steps below:

Commnad line:

npm install bootstrap --save


<link href="/vendor/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet">

Restart ‘ng serve’ or just rebuild with ‘ng build’

Solution 5:

If you are using Bootstrap 4, it doesn’t include glyphicon in self release.
So you coud use another icon package such as FontAwesome or installed the Glyphicons separately.

I am using FontAwesome and that dependencies in my cases:

  "dependencies": {
    "@angular/animations": "^5.0.0",
    "@angular/common": "^5.0.0",
    "@angular/compiler": "^5.0.0",

    "ts-node": "~3.2.0",
    "tslint": "~5.7.0",
    "typescript": "~2.4.2"

In HTML templates just place a code like that:

<i class="fa fa-refresh" aria-hidden="true"></i>

Solution 6:

if you include bootstrap files through styleUrls this will make an issue, I don’t know why, but I found that the borwser looks at different location for glyphicons.

   selector: 'app-projects',
   templateUrl: 'projects.component.html',
   styleUrls: ['projects.component.css','../../vendor/bootstrap/dist/css/bootstrap.min.css'],

using above method for calling bootstrap stylesheet file causes following error
“GET http://localhost:4200/fonts/glyphicons-halflings-regular.woff

what you can see from the error is that the browser is looking at localhost:4200/fonts/... where it should be localhost:4200/vendor/bootstrap/dist/fonts/...

anyway, a workaround is to make sure that you added the dist folder of bootstrap inside angular-cli-build.js file in vendorNpmFiles array as 'bootstrap/dist/**/*.+(js|css|eot|ttf|woff|woff2)' and remove bootstrap stylesheet from styleUrls.

then add to the index.html the following line:

<link href="/vendor/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet">

dont forget to ng serve or ng build
