how to use Glyphicons in bootstrap 4 and angular2?

问题:

I am doing an app with angular-cli and bootstrap4, but when I do some references to Glyphicons, the icons don´t appear. For example, when I add the following code:

<button type="button" class="btn btn-default btn-lg">
  <span class="glyphicon glyphicon-star" aria-hidden="true"></span> Star
</button>

I did the bootstrap installation in my angular project with:

$ npm install --save bootstrap@4.0.0-alpha.6

I should make any extra step to have the Glyphicons in bootstrap? Do I should install another npm package specific for Glyphicons?

回答1:

There are no Glyphicons now in Bootstrap 4 so you'd use another icon package such as FontAwesome or installed the Glyphicons separately.

回答2:

As already mentioned, Bootstrap 4 doesn't include glyphicon in self release.

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>

I recently purchased the entire Glyphicons set and added it to my Angular application. Here is my process:

1. Create a Glyphicons folder in the assets folder here src/assets/glyphicons
2. Add glyphicons.css to the folder above.
3. Add this in styles.css
   "styles": ["styles.css", "../src/assets/glyphicons/glyphicons.css"],
4. Create a fonts folder at src/assets/fonts
5. Inside the fonts folder place the following files
   -glyphicons-regular.eot
   -glyphicons-regular.svg
   -glyphicons-regular.ttf
   -glyphicons-regular.woff
   -glyphicons-regular.woff2
