CodePush
CodePush is a cloud service that helps mobile app developers update their apps quickly without going through the usual app store process. Think of it like instant updates for mobile apps - similar to how websites can be updated instantly. When developers find a bug or want to make small changes to their app, they can use CodePush to send these updates directly to users' phones, instead of waiting days for approval from the Apple App Store or Google Play Store. This is particularly useful for fixing urgent problems or updating content in apps. It's most commonly used with React Native and Cordova apps, which are popular ways of building mobile applications.
