In this article, we will explore the concept of headless component libraries and their use cases. We will also discuss popular options for headless UI libraries in the React Native ecosystem. Below is a summary of what we will cover:
You can find the source code repositories for examples of Tamagui, NativeWind, Dripsy, and Gluestack on my GitHub.
What is a headless UI library, and what problems can it solve?
As developers, we often face the challenge of building complex apps and websites for clients. This involves creating components that are difficult to build and style. Building custom components from scratch can be time-consuming and demanding, as we need to consider various requirements, such as ensuring cross-platform compatibility, performance, and up-to-date dependencies.
For example, let’s consider the ListBox component shown below:
[ListBox component]
As you can see, replicating this behavior in a custom React component is not easy. So how can we solve this problem? This is where headless component libraries come in. These libraries provide the logic, processing, and API for components, while allowing developers to handle the styling. In simpler terms, they handle the heavy lifting, and we only need to make them look good.
Now that we understand the basics of headless component libraries, let’s explore some popular options for React Native.
Tamagui:
Tamagui is a library that provides universally styled components for both React and React Native platforms. Its biggest advantage is that it supports both web and mobile platforms, allowing for unified styling code. The team also claims better performance compared to other libraries. To integrate Tamagui into your Expo app, follow the instructions provided. Here’s an example of using Tamagui:
[Example code using Tamagui]
Pros of Tamagui:
– Supports Expo CLI, providing more options for building React Native apps
– Uses tokens for detailed control over styling and theming
– Faster performance compared to other libraries
– Allows multiple theming options on the same screen
Cons of Tamagui:
– Tedious setup process for Expo apps
– Documentation can be difficult to follow
– Does not follow Tailwind’s styling conventions
NativeWind:
NativeWind is another library that allows developers to share styling code between React and React Native platforms. Its key feature is the ability to use Tailwind’s scripting language to style UI elements. Follow the provided steps to integrate NativeWind into your Expo app. Here’s an example of using NativeWind:
[Example code using NativeWind]
Pros of NativeWind:
– Uses Tailwind’s styling convention, making component design easier
– Small runtime, leading to better performance
– Easy setup process
– Clear documentation
– Supports Expo
Cons of NativeWind:
– None mentioned
Dripsy:
Dripsy is another React Native library that helps unify styling code between web and mobile platforms. Compared to other libraries, Dripsy has a simple setup process. To use Dripsy in your app, install it using npm. Here’s an example of using Dripsy:
[Example code using Dripsy]
Pros of Dripsy:
– Uses the sx prop for more control over UI styling
– Supports custom fonts for more customization options
– Can override themes
– Simple setup process
Cons of Dripsy:
– Not frequently updated
Gluestack:
Gluestack is an unstyled component library, similar to the previously mentioned libraries. It was created to enhance maintainability and prevent bloat. To install Gluestack in an Expo project, use the provided npm command. Here’s an example of using Gluestack:
[Example code using Gluestack]
Pros of Gluestack:
– Provides animations out of the box
– Extensive theming options
– Extensive list of components to choose from
Cons of Gluestack:
– Relies on an older version of react-native-svg, which may cause dependency conflicts
Comparison table:
Here’s a summary of the key features of the discussed libraries:
| Library | Styling Convention | Performance | Setup Process | Documentation |
| ——— | —————– | ———– | ————- | ————– |
| Tamagui | Custom tokens | Faster | Tedious | Difficult |
| NativeWind | TailwindCSS | Small runtime | Easy | Clear |
| Dripsy | sx prop | Responsive | Simple | None mentioned |
| Gluestack | Custom tokens | Good | Easy | None mentioned |
In conclusion, headless component libraries are a valuable tool for simplifying component development and styling. They handle the logic and processing, while allowing developers to focus on making the components visually appealing. Tamagui, NativeWind, Dripsy, and Gluestack are popular options in the React Native ecosystem, each with their own strengths and weaknesses.
