Angular is among the top-rated front-end Javascript frameworks with over 60,000 stars on GitHub and a huge community. It’s used for building a wide range of applications, including mobile apps, progressive web applications, single-page web applications, enterprise applications, and e-commerce sites. Software developers enjoy using Angular as it provides the best tools and practices for creating stable, feature-rich, and effective applications. 

When building their apps, software developers use various Angular component libraries. They facilitate and speed up application development in many ways and help to create solutions that would satisfy the requirements of any business from any industry niche. Thus, the admin panels greatly simplify the process of creating a user interface for developers. For example, ngx-admin offers many ready-made components and sample pages for personal and commercial purposes.

In this article, we look into the best Angular component libraries you should use in your application development in 2021. 

Why Use Angular Component Libraries?

Before we get to the most known and effective Angular component libraries, let’s find out what Angular component libraries are and why to use them in application development. 

Angular component libraries are sets of various reusable components. Each component is a piece of code that represents a designed or styled part of a web application. This way, software developers create their web applications using building blocks, just like in a puzzle.

Each component is usually kept in a folder inside an application development project and can be used throughout this project more than once.

The components are picked up depending on a particular project needs and can be individually compiled by a software developer or downloaded as a public library distributed by a large IT company.

Why do software developers use component libraries in their AngularJS development projects? There are a number of reasons:

Architecture modularity

Breaking application front-end into reusable and modular UI blocks turns development in Angular into a pleasant and clear procedure. Software developers can use the same component in different parts of a project without rewriting a code from scratch.

Stylistic unity (design)

Components help to remove the variations of code logic and styling in different parts of a source code and make application design more consistent. Moreover, they make it easier to explain how a developed application will look and feel like. Software developers can simply gather all the components in one Storybook and present them to designers and stakeholders.


As all the components are gathered in one folder, it’s much easier to maintain and share them. Moreover, if a software developer implements any changes to a component, these modifications will be applied in all the project parts where the component was used.

Simple testing

Since components are well-organized and structured in application development projects, it’s much easier to create and run tests for them. Effective components testing ensures the stability of a project, making them more robust. 


Components are easy to customize and upgrade. Therefore, if software developers want to change something about an application design, they can do that within some clicks. The changes will be applied everywhere a component or a set of components were used.
