Bootstrap vs. AngularJS in 2022

Bootstrap and AngularJS have emerged as the industry competitors for the best front-end framework for application development. The architecture, components, development style, testing, code maintainability, and even the learning curve of these frameworks vary greatly.

So, let’s have a look at the difference between Bootstrap vs AngularJS.

What is Bootstrap?

Front-end CSS framework Bootstrap, often known as Twitter Bootstrap, creates mobile-first websites. In addition to the front-end framework template, various HTML templates and JavaScript components such as jQuery can be used.

Due to responsive design templates, frameworks, grids, and most importantly, multi-site compatibility, it has grown into the second most popular UI development framework.

What is AngularJS?

Web applications can be created with the help of AngularJS based Javascript framework which is based on typeface. It is a front-end framework that does not slow down the size or performance of the application because it has built-in tools and libraries.

Reusable code can be used for any deployment goal that gives opportunities for development across all platforms. Moreover, at the object or property level, it features dynamic UI binding and bidirectional data binding which are intrinsic to its design.

speed comparison

Bootstrap is known for the simplicity that makes it easy to create online websites and applications, but it can be an issue when it comes to performance. Because of the framework’s extensive library and untapped potential, developers often criticize it.

It is also important to note that it offers customization options to improve efficiency, even if the application is heavy with content. AngularJS has demonstrated itself as a better framework for high-performance applications.

Ivy Renderer, a redesign of the AngularJS rendering engine, powers the framework. It claims to reduce the time it takes to build applications by bundling components and making them ultra-fast and small.

app design

The structure of the form view controller can be distinguished by the two-component structure of Bootstrap, including the logical layer and the view layer. While the view console provides structure for all the visual components, the Views component focuses on the visuals.

This layer contains six modules, while the logical layer contains twelve components that provide specific visual aid capabilities. AngularJS’s model-view-controller design pattern separates the functionality of the application and the view layer, making it easy to maintain a clear line between the two.

Compared to other web frameworks, AngularJS does not rely on weak event listeners and handlers to enable bidirectional data binding. Because the framework separates business logic from user interface components, developers can create a beautiful user experience while ensuring business logic works as intended.


Bootstrap-compatible plug-ins and third-party tools can be used to test applications and websites built with Bootstrap. One of the advantages of the framework is that it eliminates problems with browsers due to its single component that is reusable and does not need to be duplicated.

As an intrinsic element of the framework, all JavaScript code in AngularJS must pass a set of tests. With testing, we can create a new project from scratch and test each component as we go along.


Bootstrap is a mobile programming framework that can be used to create scalable websites and applications. A user’s browser, application, or screen size can be considered when creating responsive website content with Bootstrap.

The framework’s single universal code eliminates browser flaws and compatibility difficulties, making it a popular choice among developers.

In addition to Google and other well-known organizations, AngularJS is a complete framework capable of building enterprise level applications. Due to the command line interface and feature designs, the framework is scalable.


Vulnerabilities are frequent in front-end frameworks, and Bootstrap is no exception. The data-target property is the most common entry point for XSS exploits, and developers have noted this risk even in upgraded versions.

Popup data structure and datatip attributes, label configuration target attributes, tooltip data viewport attributes, tooltip data container attributes, tooltip data target attributes, and scrolling spy data target attributes are all common places where vulnerabilities can be exploited.

AngularJS by default treats every value as untrustworthy because it cannot be sure that an attacker will not inject malicious code via another provided property, attribute, or value. A built-in sanitizer, DomSanitizer, has been added to the framework to protect user-generated materials.

Max application size

The size of a Bootstrap application depends on the content used to create and display it. The minimum JavaScript and CSS file sizes for a full-featured Bootstrap application are 49KB and 137KB, respectively. Developers should consider unnecessary components of library packages, which may lead to application size increase regardless of minimum application size.

AngularJS applications are notorious for being massive enterprise level applications; Therefore, its size may exceed expectations. Medium-sized AngularJS applications typically weigh between 250KB and less than 500KB, which makes them smaller than competing front-end frameworks and smaller applications. When the packet size exceeds these numbers, it is necessary to use an interpreter to compress the packet.

learning curve

Bootstrap is an excellent framework for web developers. Developers familiar with the basics of HTML and CSS may find it a bit difficult to get used to the speed.

The effort will be easier if one has a working knowledge of CSS classes and Bootstrap components. The approach to designing mobile-focused applications is quite different from the previous frameworks; Therefore, developers may have to adapt to the new way of working.

AngularJS has a higher learning curve because it is a large and dynamic front-end framework. At first, it can be difficult for developers to cover a wide range of topics, but it is well worth the effort to gain a deeper understanding of alternative solutions. Developers must be comfortable with JavaScript and some other programming basics to work well with the framework.


Using Bootstrap can help you design a mobile application that is responsive and easy to use, while AngularJS is a good option if you want to build corporate software at scale without worrying about its size.
