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

The most fundamental component for building a UI.

Text

A component for displaying text.

Image

A component for displaying images.

TextInput

A component for inputting text into the app via a keyboard.

ScrollView

Provides a scrolling container that can host multiple components and views.
