Angular is known as development platform for building mobile, web and desktop applications by
using HTML, CSS, and TypeScript (JavaScript). Angular is now at version 13 and Google is the
main maintainer of the project. Bootstrap is an open source CSS framework that contains many
components for building responsive web interfaces.

An open-source front-end framework called Bootstrap is used to create a variety of responsive
web pages. It comes with numerous templates designed with CSS and JavaScript, responsive
grids, built-in elements, forms, buttons, navigational tools and other interfaces. A well-known
open-source framework built on Typescript, Angular is a web application. The platform-neutral
language Angular is utilised on a variety of platforms, including desktop, mobile, laptop, and the
web.

What is Angular 14 ?
The most well-known TypeScript-based release from Google for web development is Angular
14. Also supported by Angular 14 is the most recent TypeScript 4.7 update. Because Angular
14 by default targets ES2020, the CLI can send less code without having to down-level.
Both Angular 14 and Bootstrap 5 are widely used frameworks for creating either client-side
applications (Angular) or professional user interfaces (Bootstrap) and styling and providing
components.

With the ability to create apps for every deployment target, including the web, mobile web,
native mobile, and native desktop, Angular 14 offers itself as the platform of the modern web
developer. It gives developers an uniform way to create applications and share code. This helps
too add bootstrap to angular application.

Angular 14 is available now

The arrival of Angular v14 is something eager to announce! Its so excited to explain how each
new feature makes Angular more potent, from typed forms and isolated components to new
primitives in the Angular CDK.

The default branch in Angular organisation repositories was also renamed to main as part of
our continued efforts to build a diverse community. Additionally, this release includes a large
number of improvements and bug fixes that community members have personally contributed,
such as the addition of router strong typing and more tree-shakable error messages. They are

3. thrilled to showcase how RFCs and the community keep Angular from being the worst default
developer experience possible!

What’s new in Angular 14?
The most well-known TypeScript-based release from Google for web development is Angular
14. Also supported by Angular 14 is the most recent TypeScript 4.7 update.

A new approach to create reusable components that is integrated into the framework is
introduced in Angular 14. These components are excellent for creating a completely new user
interface or modifying an existing one and can be used in both Angular and TypeScript projects.

Features of Angular 14

These following are the some features of Angular 14
Angular CLI - Auto Completion

● You can also concur that by providing the necessary commands to produce project
artifacts like components, modules, and directives, it increases productivity.

● Although you have access to a number of commands, you almost always need to
consult the official document in order to locate commands and, more specifically,
command options.

● Real-time type-ahead auto-completion in the terminal is made possible by Angular 14's
new functionalities in the CLI.

4. Strictly typed forms

● The most frequently requested feature for Angular on GitHub is strictly typed forms,
which will enhance its model-driven approach to working with forms.

● For the first time, FormControl now accepts a generic type that specifies the kind of
value it stores.

● The Angular team built an automatic migration into Angular v14 to make sure that
existing apps wouldn't stop working after the upgrade.

Standalone Components

● Angular modules are now a possibility. Additionally, you can start using standalone
components.

● Here, the main goal of the TypeScript-based Angular framework is to change the current
state of affairs by producing artifacts like components, pipes, and directives.

● Angular submitted an RFC (Request for Comments) on standalone components in an
effort to make NgModules

Enhance Template Diagnostics

● Better template diagnostics introduced in Angular 14's most recent release enable
Angular developers to be shielded from common errors by the compiler, much like
TypeScript code is.

● Additionally, if there is a bug that would otherwise prevent it from building, then it only
fails to do so.

5. Steamlined Page Title Accessibility

● Your page title will affect how the content of your page is displayed when designing and
developing applications.

● Regarding Angular 13, the new Route.title in the Angular router simplified adding titles.

● However, in Angular 14, adding a title to your page doesn't call for any additional imports
to be added.

What is Bootstrap 5?

On the other hand, Bootstrap 5 is the most well-liked open-source front-end toolkit in the world
for quickly designing and customising responsive mobile-first websites. It features Sass
variables and mixins, a responsive grid system, a library of pre-built components, and strong
JavaScript plugins.

With the recent release of Bootstrap 5, components that were previously dependent on jQuery
could now be created in plain JavaScript. Even with the rise of contemporary frameworks and
libraries like Angular and React, jQuery has always been a necessity but also a source of
contention because these toolkits do not work well with jQuery or operate otherwise than
jQuery, which directly manipulates the DOM as opposed to using virtual DOMs.

What is the use of Bootstrap?

● Responsive CSS is provided by Bootstrap and adapts to mobile devices, tablets, and
desktops. Additionally supported by Chrome, Firefox, Internet Explorer, Safari, and
Opera, Bootstrap is cross-browser compatible.

● In less than an hour, Bootstrap can provide a usable layout with little setup. You don't
need to invest your precious time in starting from scratch.

● It will be good if you're a backend developer and need to make some UI modifications,
you don't necessarily need to be an expert in HTML and CSS to use Bootstrap.

6. ● You may easily use the components that Bootstrap includes for your website, such as
the navigation bars, dropdown menus, progress bars, and thumbnails.

● It has a sizable community and excellent documentation.

What does the Bootstrap Package contain?

Since Bootstrap is a toolkit, it contains a wide variety of tools for programmers and developers.
It includes tools for building websites and applications in HTML, CSS, and JavaScript. Plug-ins
and scaffolding are included in this.

Additionally, Bootstrap offers simple CSS and HTML design templates with a wide variety of
user interface elements. These include modals, navigation, pagination, progress bars,
typography, tables, tabs, alerts, buttons and input groups, carousels, dropdowns, forms,
Glyphicons, labels and badges, and more.

Difference between Angular and Bootstrap


S.no Angular Bootstrap
1 Google created AngularJs,
which primarily employs the
component concept to give its
created applications more
structure.
As a component of the open-source
community with widely used libraries like
CSS, Styles, and Javascript, Bootstrap was
first introduced by Twitter.
2 Mobile application development
is not supported by AngularJs.
In the creation of mobile applications,
Bootstrap plays an important role.
3 AngularJs is a Javascript-based
framework that uses the MVC
model, as was previously
mentioned. Because of this,
development is generally slower.
Bootstrap is best known for being a CSS-
based framework, making it ideal for quick
development.
4 By default, AngularJs does not
support responsiveness in its
applications.
By default, applications created with
Bootstrap are responsive.

7. 5 The routing concept is used in
AngularJs applications to
implement page/screen
navigation.
For page navigation, Bootstrap does not
support the concept of routing.
6 The two-way data binding of an
AngularJs-based application is
its key feature.
Applications built with Bootstrap do not
support two-way data binding.


The 2 Ways to embed Bootstrap into Angular


To embed the bootstrap library to your application. There are 2 ways to iinclude bootstrap to
angular,

● Angular Bootstrap via CDN

Angular Bootstrap via CDN

CDNs is known as Bootstrap Public content delivery networks. It allows to load the CSS ,
JavaScript files and remotely access its servers. For that, go to this link, copy the CSS and
JavaScript code, and then paste it in the head and body parts of your Angular application's
index.html file.
Angular Bootstrap via NPM

Install Bootstrap into your project folder using an NPM . It is an another option to include it in
your Angular project (Node Package Manager).

● install bootstrap using npm

● install jquery using npm

The Bootstrap and JQuery libraries are installed by the below mentioned scripts. The node
modules file contains the files after they have been installed.


● node_modules/jquery/dist/jquery.min.js
● node_modules/bootstrap/dist/css/bootstrap.min.css

8. ● node_modules/bootstrap/dist/js/bootstrap.min.js

How to Install Bootstrap in Your Angular Project?

We will integrate Bootstrap into your Angular project in this stage. You may integrate Bootstrap
into your Angular project in a variety of ways.

● Use the npm install command to install from npm.
● The Bootstrap files should be downloaded and added to the src/assets folder of your
Angular project.
● Use a CDN to access Bootstrap.

We will employ the first technique and set up npm to install Bootstrap from the command
line.

How to Add Bootstrap to Angular?

Here we will discuss with a few common ways to integrate Bootstrap to Angular project by
using,

● angular.json
● index.html
● styles.css
● ng-bootstrap and ngx-bootstrap
● Schematics

Bootstrap to Angular using angular.json


The files listed below should be included in your angular.json file to add Bootstrap to Angular:


● node_modules/bootstrap/dist/css/bootstrap.css in the projects>architect>build>styles
array,
● node_modules/jquery/dist/jquery.js in the projects>architect>build>scripts array,
● node_modules/bootstrap/dist/js/bootstrap.js in the projects>architect>build>scripts array

Bootstrap to Angular using index.html

You can add Bootstrap to Angular by including a tag in your src/index.html file.

● A <link> tag is added to the bootstrap.css file which is in the <head> section,
● A <script> tag is added to the jquery.js file which is before the </body> tag,
● A <script> tag is added to the bootstrap.js file which is before the </body> tag

10. Bootstrap to Angular using styles.css
Additionally, by importing the bootstrap.css file in your src/styles.css file, you can add Bootstrap
to your Angular project:

@import "~bootstrap/dist/css/bootstrap.css";

You don't need to include this file to the styles array in your angular.json or index.html files.
However, you can also add JavaScript files. Use the script array in the angular.json file or the
<script> tag in the index.html file as you did in the previous two methods.

Bootstrap to Angular using ng-bootstrap ngx-bootstrap

In this approach, the component's JavaScript implementation is entirely replaced by ng-
bootstrap. Neither bootstrap.js nor bootstrap.min.js are required. Additionally, you shouldn't use
this method to add Bootstrap to your Angular project if you want to avoid conflicts with the
jQuery or popper.js libraries.


You should install this library first,

C:\projects\my-app>npm install @ng-bootstrap/ng-bootstrap

Now your Angular application can use Bootstrap and incorporate Bootstrap components. This
helps to add bootstrap to angular.

Additionally, you can incorporate Bootstrap into your Angular project using the ngx-bootstrap
library. The first step is to add ngx-bootstrap to your project.

11. Add Bootstrap to Angular using Schematics

It's simple to add support for an external library to your project with the new ng add command in
Angular 7+. With this command, Bootstrap can be added to Angular without the need for
additional configurations. Simply enter the following command as displayed in the example
below in the terminal screen:

C:\projects\my-app>ng add @ng-bootstrap/schematics

You don't need to add jQuery.js in this example because ng-bootstrap is used instead. The
styles and components of Bootstrap are now supported.

Conclusion
Thus, we have seen several ways of including Bootstrap 5 in Angular 14 apps. The most
popular platform for building interactive user interfaces is Angular. Another popular front-end
framework is Bootstrap, which offers countless styles and design templates.

We have covered the key methods for including bootstrap in your Angular project. You can
follow any one of the methods to complete your task. It is simple to apply to your project. To
begin creating various Angular projects, add bootstrap to Angular.
