The ultimate guide to choosing a React component library

The patterns and visual elements used to build user interfaces (UIs) have evolved into a largely standardized set of design paradigms based on what works, and what users expect: Everyone knows what a clickable button looks like, or what icon will expand a menu and how it will behave.

Because of this, it makes less and less sense to build your own UI elements from scratch and more sense to consider a React component library. React component libraries provide pre-built components that conform to these user expectations for usability and aesthetics, while significantly reducing the amount of work you need to do to build great-looking apps and websites. 

This article compares the top React component libraries (as well as some new and interesting entries), and gives you the information to decide which one will suit your React project.

What is a React component library?

A React component library provides pre-built UI elements, including buttons, cards, menus, and tables, that you can use to build your apps and website front ends. This component-based approach enhances code reusability and reduces the development time and effort, allowing developers to build complex and well-designed apps with minimal effort.

Many libraries offer customization to fit your company's style guide and have extensive documentation detailing how to use their components. Additionally, (good) component libraries will follow UI development best practices and have already undergone testing for cross-browser compatibility.

React component libraries usually offer properties (props) that can be passed through to each component to change its behavior, as well as callback arguments to call a function when a user interacts with an on-screen element.

What are the advantages of using a React component library?

Here are a few important advantages to using a React component library:

Faster development

By leveraging pre-built React component libraries, you can assemble user interfaces quickly without having to build components from scratch. If you have a very unique or specific-looking design to build, you may want to consider building those components from scratch; otherwise, for more standardized designs, it makes sense to utilize these pre-built React UI libraries, and then optionally make tweaks to fit them to your brand or theme.

Code reusability

React UI libraries offer predictable reusable components and render consistent interfaces, leading to reliable and consistent UI behavior. They also provide a foundation on top of which you can implement your own reusable components for any custom solutions. Component libraries can also encourage development teams to follow best practices by providing a framework of doing things that can be emulated.

Consistency and best practices

Pre-built UI components in proven, popular libraries will generally follow best practices for design and accessibility. If you use UI components that are consistent and meet modern usability standards, your users will already be familiar with your application and how it works, it will work across mainstream web browsers, and it will be accessible to things like screen readers.

Customization

Many component libraries offer functions for easy customization, allowing you to adjust the appearance and behavior of components to meet specific branding or design requirements. If the library doesn't provide out-of-the-box attributes for customizing components, you can always alter their code to meet your needs, using them as a solid foundation for your own designs.

Comprehensive documentation

Most component libraries come with detailed documentation and examples, including demos where you can test their components live in your web browser without having to install the package locally, making it easier for you to understand and assess libraries before you implement them (and maybe find they don’t do quite what you want them to).

Accessibility

Many components come with built-in functionality for accessibility. This includes features used by screen readers, keyboard navigation, and ARIA attributes, reducing the need to develop them from scratch.

What is the best React component library?

The best React component library will depend on your project's needs, but there are several high-level factors that will help narrow down the choice from the wide array of available libraries.

Popularity: If a UI library is popular, it means there is likely to be clear documentation and a large community to help you out if you get stuck.

Longevity: If it has corporate backing or is used by a lot of big applications, and receives frequent updates, you can be sure it will be around for a while.

Purpose: Does it have extensive functionality with a large variety of components to fit your needs?

Design: Does the styling align with your aesthetic brand?

What to consider when choosing a React component library

Once you've narrowed down the list of libraries to choose from, you can choose one that meets the finer specifics of your project. 

• Figure out how customizable the React component library is. If you already have very specific designs, then it may not be possible to bend the library to fit them. 

• Look at the documentation. Is it easy to follow? If you are new to using this library, this will be useful for troubleshooting and will help with the learning curve.

• Does it have components with the properties, callbacks, and other functionality you will need to implement in your code? React Bootstrap may be good for landing pages, whereas for advanced dashboards, you may want to choose a library like Ant Design or Mantine.

• Consider how the library will impact your application's performance. Does it offer features such as tree-shaking, lazy loading, infinite scroll, or modular imports to avoid bloating your bundle size? These considerations are especially important in larger applications.

• You should select a library that will be around for a long time; it would be undesirable to pick a library that ends up unused and unmaintained. Look at its history, the number of contributors, and in particular whether it has a corporate backer; these are all good signs for longevity.

How to implement a React component library

After selecting a library that suits your project's needs, you can install the library via a package manager such as npm or yarn. The components will then be globally available in your project for you to start implementing the user interface.

For instance, if you decided to build a blog, you could use a library to quickly set up an interface with components such as cards, navigational elements, and pagination for easy navigation, and then pair your React app with a headless CMS like Contentful, where you can set up an API to easily manage and display content.

Composable architectures and composable content: A match made for developers

React component libraries often form part of a composable architecture, which allows developers to leverage the work of others to reduce development time while improving the security and usability of their applications.

Composability doesn't end at the front end. The Contentful composable content platform lets you configure a back end, without writing any code, that can deliver your content as you define it, automatically optimized for your users’ devices, and delivered by a high-speed CDN, right from the edge. Our management interfaces are user friendly, developed for content creators and editors so that they can efficiently deploy content to your apps, websites, and other channels from a unified UI.
