Integrate Bootstrap 4/jQuery with Angular 10 and Styling the UI With Navbar and Table CSS Classes

Integrate Bootstrap 4/jQuery with Angular 10 and Styling the UI With Navbar and Table CSS Classes

In this tutorial we'll learn, by example, how to use Bootstrap 4 and jQuery with Angular 10 to build professional UIs.

Angular 10 is the latest version of Angular, when writing this tutorial, and Bootstrap 4 is the latest version of Bootstrap — the most popular CSS framework. You can use Bootstrap and jQuery to create professional looking interfaces without being a CSS designer.

Note: Bootstrap 4 makes use of jQuery for implemeting many components that need DOM access. Bootstrap 5 will replace jQuery with plain JavaScript

In this tutorial, we'll particularly look at how to add Bootstrap 4 to Angular projects generated using Angular CLI 10.

In this part, we're going to style an example UI interface with Bootstrap 4, after installing and setting up the framework in the Angular 10 front-end.

In the previous tutorial we’ve:

  • Installed Angular CLI 10.
  • Generated a new front-end application using Angular CLI 10.
  • Created some UI components.

Different Ways to Integrate Bootstrap 4 with Angular 10

There are many ways to add Bootstrap 4 to Angular projects:

  • Installing bootstrap and jquery via npm and add adding scripts and styles to angular.json.
  • Importing bootstrap style and script files in src/index.html. You can use a bootstrap 4 CDN.
  • Installing bootstrap via npm and importing @import "~bootstrap/dist/css/bootstrap.css"; in src/styles.css.
  • Installing and using ng-bootstrap npm install --save @ng-bootstrap/ng-bootstrap: It's a library that contains native Angular components for Bootstrap’s markup and CSS styles. It's not dependent on jQuery or Bootstrap’s JavaScript.

How to Work with This Tutorial?

To complete this tutorial, you'll need to, either:

  • Start with the previous tutorial, which takes you from installing the Angular CLI 10 to calling the RESTful API
  • Clone the font-end project from GitHub and follow the steps in the previous tutorial for setting up the project.
  • Directly follow the steps to integrate Bootstrap 4 in your own Angular 10 project.

How to add Bootstrap 4 to your Angular 10 Front-End?

After seeing different ways to add Bootstrap 4 to Angular 10, let's now style our Angular 10 front-end UI, built in the previous tutorial, with Bootstrap. We'll use the first approach i.e we'll install bootstrap from npm and then we'll include bootstrap.css CSS file, jQuery and Popover.js

Installing Bootstrap 4 and jQuery

Head over to your project, you created in the previous tutorial, navigate inside your Angular 10 front-end application:

$ cd frontend

Next, install bootstrap and jquery from npm using:

$ npm install --save bootstrap jquery

Adding Bootstrap 4 to Angular CLI 10

Next, open angular.json. You should similar content to the following:

{

"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"version": 1,
"newProjectRoot": "projects",
"projects": {
    "crmapp": {
    "root": "",
    "sourceRoot": "src",
    "projectType": "application",
    "prefix": "app",
    "schematics": {},
    "architect": {
        "build": {
        "builder": "@angular-devkit/build-angular:browser",
        "options": {
        "outputPath": "dist/crmapp",
        "index": "src/index.html",
        "main": "src/main.ts",
        "polyfills": "src/polyfills.ts",
        "tsConfig": "src/tsconfig.app.json",
        "assets": [
            "src/favicon.ico",
            "src/assets"
        ],
        "styles": [
            "src/styles.css"
        ],
        "scripts": []
        },

...
},
"defaultProject": "crmapp"
}

Under projects -> architect -> build -> scripts add node_modules/jquery/dist/jquery.min.js and node_modules/bootstrap/dist/js/bootstrap.min.js:

"scripts": [
    "node_modules/jquery/dist/jquery.min.js",
    "node_modules/bootstrap/dist/js/bootstrap.min.js"
]

Under projects -> architect -> build -> styles add node_modules/bootstrap/dist/css/bootstrap.min.css:

"styles": [
    "src/styles.css",
    "node_modules/bootstrap/dist/css/bootstrap.min.css"
],

That's it. You can now use Bootstrap 4 in your Angular 10 front-end application just like you would normally do.

Styling Angular 10 Components with Bootstrap 4

Let's take an example. Go ahead and open src/app/app.component.html and update it to add a Bootstrap navigation bar:

<nav  class="navbar navbar-expand-lg navbar-light bg-light">
    <a  class="navbar-brand"  href="#">Angular CRM</a>
    <button  class="navbar-toggler"  type="button"  data-toggle="collapse"  data-target="#navbarSupportedContent"  aria-controls="navbarSupportedContent"  aria-expanded="false"  aria-label="Toggle navigation">
    <span  class="navbar-toggler-icon"></span>
    </button>
<div  class="collapse navbar-collapse"  id="navbarSupportedContent">
    <ul  class="navbar-nav mr-auto">
        <li  class="nav-item active">
        <a  class="nav-link"  href="#">Home <span  class="sr-only">(current)</span></a>
        </li>
        <li  class="nav-item dropdown">
        <a  class="nav-link dropdown-toggle"  href="#"  id="navbarDropdown"  role="button"  data-toggle="dropdown"  aria-haspopup="true"  aria-expanded="false">
        Actions
        </a>
        <div  class="dropdown-menu"  aria-labelledby="navbarDropdown">
        <a  class="dropdown-item" [routerLink]="'/accounts'"> Accounts </a>
        <a  class="dropdown-item" [routerLink]="'/create-account'"> Create Account </a>
        <div  class="dropdown-divider"></div>
        <a  class="dropdown-item" [routerLink]="'/contacts'"> Contacts </a>
        <a  class="dropdown-item" [routerLink]="'/create-contact'"> Create Contact </a>
        <div  class="dropdown-divider"></div>
        <a  class="dropdown-item" [routerLink]="'/leads'"> Leads </a>
        <a  class="dropdown-item" [routerLink]="'/create-lead'"> Create Lead </a>
        <div  class="dropdown-divider"></div>
        <a  class="dropdown-item" [routerLink]="'/opportunities'"> Opportunities </a>
        <a  class="dropdown-item" [routerLink]="'/create-opportunity'"> Create Opportunity </a>
        </div>
        </li>
</ul>
</div>
</nav>
<div  class="container-fluid">
    <router-outlet></router-outlet>
</div>

Now, let's style contact list component. Open src/app/contact-list.component.html and add:

<h1>
My Contacts
</h1>
<div>
<table  class="table">
<thead>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Phone</th>
<th>Email</th>
<th>Address</th>
</tr>
</thead>
<tr *ngFor="let contact of contacts">
    <td> {{ contact.first_name }} </td>
    <td> {{ contact.last_name }} </td>
    <td> {{ contact.phone }} </td>
    <td> {{ contact.email }} </td>
    <td> {{ contact.address }} </td>
</tr>
</table>
</div>

This is a screen-shot of the result after adding Bootstrap 4 classes:
