Core Components and APIs

React Native provides a number of built-in Core Components ready for you to use in your app. You can find them all in the left sidebar (or menu above, if you are on a narrow screen). If you're not sure where to get started, take a look at the following categories:

• Basic Components
• User Interface
• List Views
• iOS-specific
• Android-specific
• Others

You're not limited to the components and APIs bundled with React Native. React Native has a community of thousands of developers. If you're looking for a library that does something specific, please refer to this guide about finding libraries.

Basic Components

Most apps will end up using one of these basic components.

View
