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
<button *ngIf="pos.name == uname" type="button" class="btn btn-default btn-sm delete" (click)="DeleteBulletin();">
<span class="glyphicon glyphicon-trash glyph"></span> Delete
</button>
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-

Answer 1

Boostrap 4 does not support Glyphicons anymore, you can use Font Awesome instead:
npm install --save fortawesome/fontawesome-free
and add the css File to your .angular-cli.json
"apps": [
{
....
"styles": [
"styles.css",
"../node_modules/bootstrap/dist/css/bootstrap.css",
"../node_modules/font-awesome/css/font-awesome.css"
],
...
}
]
],
Replace CSS class with the Font Awesome classes:
<i class="navbar-toggler-icon fa fa-bars"> </i>
recompile app: ng serve
Update:
Since Font Font-Awesome 5 and Angular 5 there is an offical angular-fontawesome package available:

You have to import
<link data-require="bootstrap-css#3.3.6" data-semver="3.3.6" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.css" />
to your index.html

I installed bootstrap3 as npm install bootstrap#3 and it started working
just need to add in angular-cli.json:-
"styles": [
"styles.css",
"../node_modules/bootstrap/dist/css/bootstrap.css"
],

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.js:
// Angular-CLI build configuration
// This file lists all the node_modules files that will be used in a build
// Also see https://github.com/angular/angular-cli/wiki/3rd-party-libs
/* global require, module */
var Angular2App = require('angular-cli/lib/broccoli/angular2-app');
module.exports = function(defaults) {
return new Angular2App(defaults, {
vendorNpmFiles: [
'systemjs/dist/system-polyfills.js',
'systemjs/dist/system.src.js',
'zone.js/dist/**/*.+(js|js.map)',
'es6-shim/es6-shim.js',
'reflect-metadata/**/*.+(ts|js|js.map)',
'rxjs/**/*.+(js|js.map)',
'#angular/**/*.+(js|js.map)',
'bootstrap/dist/css/bootstrap.min.css',
'bootstrap/dist/fonts/*'
]
});
};
For completeness, setup process for bootstrap was in those few steps below:
Commnad line:
npm install bootstrap --save
index.html:
<link href="/vendor/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet">
Restart 'ng serve' or just rebuild with 'ng build'

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",
"#angular/core": "^5.0.0",
"#angular/forms": "^5.0.0",
"#angular/http": "^5.0.0",
"#angular/platform-browser": "^5.0.0",
"#angular/platform-browser-dynamic": "^5.0.0",
"#angular/router": "^5.0.0",
"#ng-bootstrap/ng-bootstrap": "1.0.0-beta.9",
"bootstrap": "4.0.0",
"core-js": "^2.4.1",
"font-awesome": "^4.7.0",
"jquery": "^3.2.1",
"popper.js": "^1.12.9",
"rxjs": "^5.5.2",
"zone.js": "^0.8.14"
},
"devDependencies": {
"#angular/cli": "^1.6.5",
"#angular/compiler-cli": "^5.0.0",
"#angular/language-service": "^5.0.0",
"#types/jasmine": "~2.5.53",
"#types/jasminewd2": "~2.0.2",
"#types/node": "~6.0.60",
"codelyzer": "^4.0.1",
"jasmine-core": "~2.6.2",
"jasmine-spec-reporter": "~4.1.0",
"karma": "~1.7.0",
"karma-chrome-launcher": "~2.1.1",

"protractor": "~5.1.2",
"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>

Answer 6

if you are using bootstrap 4 glyphicon is no longer supported you should try an old version

Answer 7

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.
#Component({
moduleId: module.id,
selector: 'app-projects',
templateUrl: 'projects.component.html',
styleUrls: ['projects.component.css','../../vendor/bootstrap/dist/css/bootstrap.min.css'],
providers:[ProjectsService]
})
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

Answer 8

Please run
npm install glyphicons --save
and than please import glyphicons in your component
import icons from 'glyphicons';
var icons = require('glyphicons');
console.info('This is' + icons.heart+ ' Glyphicons!')
You can check once in your browser console.

The advice with FontAwesome is correct but only partially. If you just follow the FontAwesome instructions you will fail in an Angular project.
Instead check the hint on this page:
Font Awesome now has an official Angular component that’s available
for all who want to easily use our icons in projects. If you are using
Angular, you need the angular-fontawesome package or Web Fonts with
CSS.
Okay this means in an Angular project you need to use the following package: Angular FontAwesome
The best page that I have found for me as I am using NPM was this page.
So basically you need to:
Install FontAwesome in NPM
Import the module AngularFontAwesomeModule in your app.module.ts
Add the CSS in the angular-cli.json file
The details are all described in the link above.
To finally add an icon you can add a power-off icon in the app.component.html file:
Code:
<fa-icon [icon]="faPowerOff"></fa-icon>
AND you need to add the code in the related app.component.ts file:
Code:
import { faPowerOff } from '#fortawesome/free-solid-svg-icons';
...
export class AppComponent implements OnInit {
faPowerOff = faPowerOff;
...
ONE IMPORTANT NOTE!
Please realize you need to install the correct version of AngularFontawesome in NPM for your Angular version. Check this page for the compatibility table.
I used Angular 5 so I had to install it like this:
npm install #fortawesome/angular-fontawesome#0.1.1
The entry will then be added to your package.json file.

Answer 10

I did the same as #Sebastian Viereck . But i did
npm install --save-dev #fortawesome/fontawesome-free
and on the angular.json
"styles": ["node_modules/bootstrap/dist/css/bootstrap.css",
"node_modules/#fortawesome/fontawesome-free/css/all.min.css",
"src/styles.css"
],
It looks that fontawesome has a new paid version

Answer 11

From https://www.w3schools.com/bootstrap4/bootstrap_icons.asp -
Bootstrap 4 does not have its own icon library (Glyphicons from bootstrap 3 are not supported in BS4). However, there are many free icon libraries to choose from, such as Font Awesome and Google Material Design Icons. To use Font Awesome icons, follow these steps:
Install Font-Awesome from the terminal in your project folder
npm install --save font-awesome
and add the following line to your main stylesheet -
#import "~font-awesome/css/font-awesome.css";
You can now access all the icons available in the installed Font-Awesome library. Refer this link for the complete list of icons - Official Font Awesome Website
