CodePush vs Expo Sketch: What are the differences?
CodePush: Push code updates to your apps, instantly (by 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 certain updates to (e.g. JS, HTML, CSS and image changes), and that apps can query for updates from (using our provided client SDKs); Expo Sketch: A Playground for React Native. Instantly test your code on a device, or in the browser. You can either preview the component on the emulator inside the browser, or open it directly on your device with the Expo app. The UI updates as you type — every keystroke, without having to hit save.
CodePush and Expo Sketch belong to "Cross-Platform Mobile Tools" category of the tech stack.
CodePush is an open source tool with 3.7K GitHub stars and 393 GitHub forks. Here's a link to CodePush's open source repository on GitHub.
