Deploy React Native offline bundle to device instruction - duyluandethuong/react-native-tips-tricks GitHub Wiki

If anyone wants to improve on these instructions and add them to the docs, feel free, I can do it later if nobody else jumps on it - I just wanted to document it somewhere for now.

Open iOS/AppDelegate.m

Comment out jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle"];

Uncomment jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

Start up the packager with npm start and then run curl http://localhost:8081/index.ios.bundle -o main.jsbundle - if this fails (as it did on my machine) add the --ipv4 flag to the end of it.

In XCode, right click on your project directory and click Add Files to "Project Name Here" - choose the main.jsbundle file that you generated.

You can now run the app on a device (either via usb or TestFlight) without needing to have a server running.
