What is Microsoft CodePush?

Microsoft CodePush is a cloud service that enables Cordova and 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, and that apps can query for updates from. This allows you to have a more deterministic and direct engagement cycle with your end-users, while also avoiding the need to recompile and redistribute your app via the respective app stores.

Understanding the Basics of Microsoft CodePush

Before diving into the specifics of Microsoft CodePush, it's crucial to understand the basic concepts that underpin this service. At its core, CodePush is a cloud service that allows developers to release updates to their mobile applications directly to the end user's device. This bypasses the traditional method of app distribution through app stores, which can be time-consuming and cumbersome.

CodePush operates as a central repository that developers can publish updates to. The mobile applications, in turn, can query this repository for updates. This setup allows for a more direct engagement cycle with end-users, as developers can push updates at any time, and users can receive these updates without having to manually update the app through the app store.

How Does CodePush Work?

CodePush works by packaging the application's JavaScript and HTML files into a bundle. This bundle is then uploaded to the CodePush server. When an application checks for an update, the server sends the latest bundle to the device. The application then loads the updated files, effectively updating the app on the user's device.

This process is seamless to the user, who may not even realize that an update has occurred. This is a significant advantage of using CodePush, as it eliminates the need for users to manually update their apps, which can be a barrier to maintaining the most recent app version on a user's device.

Benefits of Using Microsoft CodePush

Microsoft CodePush offers several benefits to both developers and end-users. For developers, the ability to push updates directly to devices can significantly speed up the update cycle. This can be particularly beneficial for apps that require frequent updates or for those that need to respond quickly to issues or bugs.

For users, CodePush provides a seamless update experience. Updates are downloaded in the background and applied when the app is restarted. This means that users don't have to deal with the inconvenience of manually updating apps, which can lead to a better user experience.

Increased Engagement

By enabling developers to push updates directly to devices, CodePush can help increase user engagement. Users are more likely to use an app that is regularly updated with new features and improvements. Furthermore, by eliminating the need for manual updates, users are more likely to maintain the latest version of the app on their device.

Increased engagement can lead to higher user retention rates, which is a key metric for the success of any mobile app. Therefore, using a service like CodePush can be a strategic move for developers looking to boost their app's performance.

How to Use Microsoft CodePush

Using Microsoft CodePush involves a few steps. First, you'll need to install the CodePush command-line interface (CLI) on your development machine. This can be done using the Node Package Manager (npm) with the command 'npm install -g code-push-cli'.

Once the CLI is installed, you can use it to create a new CodePush app. This is done with the command 'code-push app add [AppName]'. This command will return an access key, which you'll need to configure your mobile app to use CodePush.

Integrating CodePush into Your App

Integrating CodePush into your app requires modifying your app's code to check for and apply updates from CodePush. This is done by adding the CodePush SDK to your app and calling the 'checkForUpdate' method at an appropriate place in your app's lifecycle.

Once integrated, your app will automatically check for updates from CodePush whenever it is started. If an update is available, it will be downloaded and applied the next time the app is restarted.


Microsoft CodePush is a powerful tool for mobile app developers. It offers a more direct and efficient way to deliver updates to users' devices, bypassing the traditional app store distribution process. This can lead to increased user engagement and retention, making it a valuable tool for any developer's toolkit.

Whether you're a seasoned developer or just starting out, CodePush offers a range of benefits that can help you deliver a better app experience to your users. So why not give it a try and see how it can improve your app development process?
