Angular Vs Bootstrap- A Comparison Of Frontend Frameworks

Angular vs Bootstrap

In this competitive market, a creative and responsive UI plays a vital role in the success of web solutions. So for developers, it is important to choose the best frontend framework for app development. Angular and Bootstrap are the two popular frameworks used by developers, but choosing the best one for a project is not an easy task. Angular is a TypeScript based framework with immense codes and vast tools for app development whereas Bootstrap is an HTML/CSS/JS framework with ready-made components. The fundamentals of both the frameworks are different- starting from its architecture, coding style and even its learning curve.  Here we’ll compare Angular vs Bootstrap to help you to choose the best one. Before comparing both the frameworks, let us see the overview of each one in detail. 

What Is Angular?

Released in 2016, it is a typescript-based Javascript framework to build scalable web applications. Angular has some in-built tools and libraries that don’t affect the size or app speed. It provides a dynamic UI binding at plain object or property level, and a two-way data binding is integral to its architecture.

What Is Bootstrap?

Bootstrap is an open-source front-end CSS framework used to create responsive mobile-first websites. It is popular UI development framework for its responsive design templates, frameworks, grids and multi-site compatibility.

It is used to build Microblogging apps, social media apps, ecommerce websites, content based apps, geo-location apps, on-demand apps, payment apps and responsive web apps also.

Vogue, Lyft, Whatsapp are some of the popular apps built by using Bootstrap.

Angular Vs Bootstrap- A Comparison

1. Application Architecture-


Angular has a Model-View-Controller architecture pattern that isolates the app logic from user interface layer and efficiently supports the separation of concerns. Architecture helps to organize the code components as per design and performance variations. Also, it simplifies the development structure by combining MVC pattern and two-way data binding. In contrast to other web frameworks, which implement two-way data binding by using fragile event listeners and handlers, Angular makes this process an  integral function of its architecture. The framework isolates the business logic from UI components, that helps developers to design a neat user interface with smooth business logic applicable.


Bootstrap architecture can be summarized as a View-View-Controller architecture due to its built that use Logic layer and view layer. View component focuses on visual displays, while the view-controller sets out all the visual components’  behavior within the framework. There are six modules in view layer and twelve components in logic layer that provide unique functionality to the corresponding visual aid. 

While developing a webpage, bootstrap supports the Model-View-Controller architecture pattern. One should always remember that, while creating a web app using the MVC design principle, the framework would serve as the view components. 

2. Performance-


Angular has proved itself for providing superior performance. The advanced change detection mechanism and ahead-of-time compilation reduces the number of times DOM manipulates, pre-compiled HTML, and app components before the browser downloads and uses them. 


It is known for its user-centric ease for developing websites and web applications. Mostly, developers criticized the framework for its vast library and unused resources that lead to slower performance. But it offer extensive customization features to improve app performance regardless of it being content-heavy. Use of requirement specific resources, like using source code instead of entire library, reduces the bulk over the website. Minimal and lean use of CSS and JavaScript codes decreases the load on the downloading browser and increases efficiency while displaying. Some common workarounds would include compressing images, moving the server closer to the audience and using CDN for high-performance loaded website. With some best practices, Bootstrap can have a lower fully loading time of 2.1 seconds of a page size that is 1.3 MB.

3. User Experience-


Angular is a popular frontend framework to build user interfaces and independently handle frontend. Framework has been divided into components, classes and segmentations for clean coding architecture, so it manages the users’ interaction through templates. Angular manages the display of data to the users in a systematic way. Also, the library is responsible for handling reactivity, and asynchronous programming responsible for making app responsive to users and their actions.  Template language helps to keep the data binding and rendering of HTML on the same page. That implies, each time the application page is rendered, the framework interacts with the template syntax and updates the view immediately. Again, keeping no delay between updating and displaying the data to the users.


It was developed as a web responsive frontend framework to render a standardized and best user experience. Framework’s responsive design gives web users, developers, and viewers consistency across all platforms, that would directly increase the trust and value of the app. Available templates, themes, drop-down menus, buttons, sliders, built on jQuery and other interactive components provides seamless experience through web application. To improve the user experience at an high extent, bootstrap UI HTML Kits Get Shit Done, Shards Dashboard Lite React, Stream can be used. Other free Bootstrap XD UI Kits include Adobe XD Bootstrap 4 Grid Template, Take Me, Universal Web UI Kit.

4. Rapid Development-


With Angular, developers need to invest less effort and time by reusing codes and streamlining the development process. It gives more functionality with short codes, that makes it productive for teams working on back-to-back similar projects. Angular framework offers flexibility for coding like no other framework due to its simple design architecture. It handles heavy web applications including lots of features and components exceptionally well. In terms of flexibility, it allows beginners to easily use and make modifications in their app projects seamlessly.


It is known for quickly developing apps and saves time with the help of its extensive documentation. Being developer-friendly, Bootstrap libraries consist of some class components, because of which there is no need for coding knowledge to develop an app. You need an understanding of markup language like HTML and styling basics like CSS preprocessors to implement Bootstrap in your projects. Ready-made components, JS plugins and documented synergy also save time and energy to remember specifications of each element. Cross-browser compatibility and consistency minimizes the bugs on various platforms and aids in upgrading an app within a short time span.

5. Security-


User-generated websites need high level of security and management. Cross-site scripting is an important vulnerability that client-side platforms need protection against. These attacks can be avoided by some built-in provisions that the framework provides. Since there’s no assurance that attackers will not enter malicious code through the property, attribute, or any offered value, Angular treats each value as untrustworthy by default. 

Framework has introduced inner HTML to display the user-generated content and built-in sanitizer – DomSanitizer – as a security feature. Other security resources include maintaining updated libraries, updating content security policy in security-reviewed code and using AOT for compiling HTML templates and components. Hence, by following the best practices with its internal security features and external tools makes Angular a secured framework.

6. Learning Curve-


It has a steep learning curve. Developers may find it challenging to cover numerous topics at first, but it is worth giving time at the starting phase for better understanding of its workarounds. For productive development, developers should be confident with Javascript and some other programming concepts. Angular CLI has gentle learning curve for experienced developers, and developers can predict compilation behavior. This benefit makes it possible to generate smooth builds and reduce iterating efforts that lowers the code quality. It is advisable to pick tech stacks according to the necessities of your upcoming projects since Angular gives the best solutions to solve the most difficult issues in large-scale applications. 


It is a developer-friendly framework having less learning curve for developers who are well trained with HTML and CSS basics. Also, it’d be necessary to know and acquire oneself with CSS classes and bootstrap components to ease the task. It uses different approach than other frameworks, i.e, developing mobile-centric apps and developers may have to adapt to the new style.

Because of extensive documentation, it becomes quick and easy to develop a web app without knowing the code, but customization might need knowledge of HTML and CSS. Using of this framework, it can be a great place to start for beginners considering its scope as the most popular framework and its use for developing web apps.
