Summary: This change enables developers to tell the Geolocation module to skip its permissions requests so the app can manage the permissions requests on its own. React Native Android's Geolocation module already requires apps to request permissions on their own. Currently, the Geolocation module automatically makes permissions requests for you based on what you've specified in your property list file. However, the property list file doesn't always represent what permissions the app wants right now. For example, suppose an app sometimes wants location when "in use" and sometimes wants location "always" depending on what app features the user has engaged with. The Geolocation API will request the "always" location permission even if that's not what the app wants for the current scenario. This change enables developers to tell the Geolocation module to skip permission requests so that the app can explicitly ask for the appropriate permissions. By default, Geolocation will still ask for permissions so this is not a breaking change. This change adds a method to Geolocation that is not supported by the web spec for geolocation (`setRNConfiguration`). This method includes `RN` in the name to minimize the chances that the web spec will introduce an API with the same name. **Test plan (required)** Verified that Geolocation requests permissions by default and when `skipPermissionRequests` is `false`. Verified the permission requests are skipped when `skipPermissionRequests` is `true`. Also, my team is using this change in our app. Adam Comella Microsoft Corp.

React Native ·
Learn once, write anywhere: Build mobile apps with React.
- Build native mobile apps using JavaScript and React: React Native lets you build mobile apps using only JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components.
- A React Native app is a real mobile app: With React Native, you don't build a "mobile web app", an "HTML5 app", or a "hybrid app". You build a real mobile app that's indistinguishable from an app built using Objective-C, Java, or Swift. React Native uses the same fundamental UI building blocks as regular iOS and Android apps. You just put those building blocks together using JavaScript and React.
- Don't waste time recompiling: React Native lets you build your app faster. Instead of recompiling, you can reload your app instantly. With hot reloading, you can even run new code while retaining your application state. Give it a try - it's a magical experience.
- Use native code when you need to: React Native combines smoothly with components written in Objective-C, Java, or Swift. It's simple to drop down to native code if you need to optimize a few aspects of your application. It's also easy to build part of your app in React Native, and part of your app using native code directly - that's how the Facebook app works.
The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.
See the official React Native website for an introduction to React Native.
Supported operating systems are >= Android 4.1 (API 16) and >= iOS 8.0.
Getting Started
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
Documentation
The website’s documentation is divided into multiple sections.
- There are Guides that discuss topics like debugging, integrating with existing apps, and the gesture responder system.
- The Components section covers React components such as
View
andButton
. - The APIs section covers other libraries like Animated and StyleSheet that aren’t React components themselves.
- Finally, React Native provides a small number of Polyfills that offer web-like APIs.
Another great way to learn more about the components and APIs included with React Native is to read their source. Look under the Libraries/Components
directory for components like ScrollView
and TextInput
, for example. The RNTester example is also here to demonstrate some of the ways to use these components. From the source you can get an accurate understanding of each component’s behavior and API.
The React Native documentation only discusses the components, APIs and topics specific to React Native (React on iOS and Android). For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
Upgrading
React Native is under active development. See the guide on upgrading React Native to keep your project up-to-date.
