CodePush
ELI5 — The Vibe Check
CodePush was Microsoft's OTA update service for React Native that let you push JS fixes directly to phones. It's been superseded by Expo Updates and other alternatives, but the concept lives on — update your app without waiting for Apple's approval.
Real Talk
A service originally by Microsoft (now part of App Center, being retired) that enabled over-the-air updates for React Native and Cordova apps. CodePush allowed developers to push JavaScript and asset changes directly to users' devices, bypassing app store review for non-native changes.
When You'll Hear This
"CodePush is being retired — migrate to Expo Updates or a self-hosted solution." / "We used CodePush for years to ship hotfixes in minutes instead of waiting days for App Store review."
