How to Use Code Push for Over-the-air Updates in React Native

by

React Native is a popular framework for building mobile applications using JavaScript and React. One of its key features is the ability to deliver updates quickly without going through app store approval processes. CodePush, a service from Microsoft, enables over-the-air updates for React Native apps, allowing developers to push JavaScript and assets directly to users.

What is CodePush?

CodePush is a cloud service that integrates with your React Native app to deliver updates instantly. It allows you to push code changes, bug fixes, and new features directly to users’ devices, bypassing the traditional app store update cycle. This results in faster deployment and a better user experience.

Setting Up CodePush in React Native

To start using CodePush, follow these steps:

  • Sign up for a Microsoft App Center account.
  • Create a new app in App Center for your React Native project.
  • Install the CodePush CLI globally using npm:

npm install -g code-push

  • Link your React Native app to CodePush:

Run the command:

code-push app add <appName> <platform> React-Native

Integrating CodePush into Your React Native App

Next, install the React Native CodePush SDK:

npm install react-native-code-push

Link the SDK to your project:

npx react-native link react-native-code-push

Configuring CodePush in Your Application

Import CodePush and wrap your main app component:

import codePush from “react-native-code-push”;

Wrap your component:

let codePushOptions = { checkFrequency: codePush.CheckFrequency.ON_APP_START };

export default codePush(codePushOptions)(App);

Publishing Updates

To release an update, run:

code-push release-react <appName> <platform> –d <deploymentName>

Managing Updates and Best Practices

Monitor your updates through the App Center dashboard. It’s important to:

  • Test updates thoroughly before releasing.
  • Use staged deployments to control rollout.
  • Inform users about updates that require app store approval.

By following these steps, you can efficiently deliver over-the-air updates to your React Native app, ensuring a seamless experience for your users.
