Dulmandakh 0bbac18cf0 circle ci: yarn cache uses package.json checksum as a key
Summary:
To better utilize Circle CI caching, yarn cache will use package.json file checksum as key in addition to arch, because in most cases yarn cache will be updated if package.json updates.

Circle CI sample apps use yarn.lock checksum as yarn cache key, but react-native don't have yarn.lock in the repo, so it's best to use package.json instead.
Closes https://github.com/facebook/react-native/pull/19395

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 websites documentation is divided into multiple sections.

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 components 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.
