code-push

What is code-push?

The code-push npm package is a service that enables React Native and Cordova developers to deploy mobile app updates directly to their users' devices. This allows for instant updates without requiring users to go through the app store update process.

What are code-push's main functionalities?

Release Updates

This feature allows developers to release updates to their apps. The `release` method takes parameters such as the app name, deployment name, update contents, target binary version, description, whether the update is mandatory, and the rollout percentage.

const codePush = require('code-push');

codePush.release(appName, deploymentName, updateContents, targetBinaryVersion, description, isMandatory, rolloutPercentage);

Check for Updates

This feature allows the app to check if there are any updates available. The `checkForUpdate` method takes a deployment key and returns a promise that resolves with the update information if an update is available.

const codePush = require('code-push');

codePush.checkForUpdate(deploymentKey).then((update) => {
  if (!update) {
    console.log('The app is up to date.');
  } else {
    console.log('An update is available: ' + update.description);
  }
});

Rollback Updates

This feature allows developers to rollback to a previous version of the app. The `rollback` method takes parameters such as the app name, deployment name, and target binary version.

const codePush = require('code-push');

codePush.rollback(appName, deploymentName, targetBinaryVersion);

Other packages similar to code-push

expo-updates

Expo Updates is a service that allows developers to deploy updates to their React Native apps built with Expo. It provides similar functionality to CodePush, such as over-the-air updates, but is specifically designed for apps built with the Expo framework.

appcenter

App Center is a comprehensive app lifecycle management service by Microsoft that includes features for build, test, distribute, and monitor. It includes CodePush as part of its distribution service, providing similar over-the-air update capabilities along with additional features for continuous integration and delivery.

react-native-update

React Native Update is a library that provides over-the-air updates for React Native apps. It offers similar functionality to CodePush, allowing developers to push updates directly to users without going through the app store. However, it is less feature-rich compared to CodePush and App Center.

CodePush

CodePush is a cloud service that enables React Native developers to deploy mobile app updates directly to their users' devices. It works by acting as a central repository that developers can publish updates to (JS, HTML, CSS and images), and that apps can query for updates from (using provided client SDK for React Native). This allows you to have a more deterministic and direct engagement model with your userbase, when addressing bugs and/or adding small features that don't require you to re-build a binary and re-distribute it through the respective app stores.

To get started using CodePush, refer to our documentation, otherwise, read the following steps if you'd like to build/contribute to the project from source.

NOTE: If you need information about code-push management CLI, you can find it in v3.0.1.

Dev Setup

• Install Node.js
• Install Git
• Clone the Repository: git clone https://github.com/Microsoft/code-push.git

Building

• Run npm run setup to install the NPM dependencies of management SDK.
• Run npm run build to build the management SDK for testing.
• Run npm run build:release to build the release version of management SDK.

Running Tests

• To run tests, run npm run test from the root of the project.
• You can use debug mode for tests with .vscode/launch.json file.

Coding Conventions

• Use double quotes for strings
• Use four space tabs
• Use camelCase for local variables and imported modules, PascalCase for types, and dash-case for file names

CodePush Management SDK (Node.js)

A JavaScript library for programmatically managing your CodePush account (e.g. creating apps, promoting releases), which allows authoring Node.js-based build and/or deployment scripts, without needing to shell out to the App Center CLI.

Getting Started

1. Create a token to authenticate with the CodePush server using the following App Center CLI command:

   appcenter tokens create -d "DESCRIPTION_OF_THE_TOKEN"
   

   Please copy your API Token and keep it secret. You won't be able to see it again.

2. Install the management SDK by running npm install code-push --save

3. Import it using one of the following statement: (using ES6 syntax as applicable):

   • On commonjs environments:

   const CodePush = require("code-push");
   

   • Using ES6 syntax with tsconfig.json:

   import CodePush from "code-push";
   

4. Create an instance of the CodePush class, passing it the API Token you created or retrieved in step #1:

   const codePush = new CodePush("YOUR_API_TOKEN");
   

5. Begin automating the management of your account! For more details on what you can do with this codePush object, refer to the API reference section below.

API Reference

The code-push module exports a single class (typically referred to as CodePush), which represents a proxy to the CodePush account management REST API. This class has a single constructor for authenticating with the CodePush service, and a collection of instance methods that correspond to the commands in the App Center CLI, which allow you to programmatically control every aspect of your CodePush account.

Constructors

• CodePush(accessKey: string) - Creates a new instance of the CodePush management SDK, using the specified access key to authenticated with the server.

Methods

Note: access key here refers to an AppCenter API Token.

• addAccessKey(description: string): Promise<AccessKey> - Creates a new access key with the specified description (e.g. "VSTS CI").

• addApp(name: string, os: string, platform: string, manuallyProvisionDeployments: boolean = false): Promise<App> - Creates a new CodePush app with the specified name, os, and platform. If the default deployments of "Staging" and "Production" are not desired, pass a value of true for the manuallyProvisionDeployments parameter.

• addCollaborator(appName: string, email: string): Promise<void> - Adds the specified CodePush user as a collaborator to the specified CodePush app.

• addDeployment(appName: string, deploymentName: string): Promise<Deployment> - Creates a new deployment with the specified name, and associated with the specified app.

Error Handling

When an error occurs in any of the methods, the promise will be rejected with a CodePushError object with the following properties:

• message: A user-friendly message that describes the error.
• statusCode: An HTTP response code that identifies the category of error:
  • CodePush.ERROR_GATEWAY_TIMEOUT: A network error prevented you from connecting to the CodePush server.
  • CodePush.ERROR_INTERNAL_SERVER: An error occurred internally on the CodePush server.
  • CodePush.ERROR_NOT_FOUND: The resource you are attempting to retrieve does not exist.
  • CodePush.ERROR_CONFLICT: The resource you are attempting to create already exists.
  • CodePush.ERROR_UNAUTHORIZED: The access key you configured is invalid or expired.
