React Native Debugger on Expo SDK 48

Question

I can't run React Native Debugger from Android Studio< Expo SDK 48. There is no Debug Remote JS item in the developer menu, but I have the Open JS Debugger item. When I select it, Devtools is revealed. But in React Native Debugger my device not connected on my port 19000.

Im read documentation and install many librarys and not working yet.

Answer 1

Same issue. I found this solution and it works for me

app.json configuration

"jsEngine": "hermes",
"ios": {
   "jsEngine": "jsc",
   "supportsTablet": true
},

and run project with npx expo start --localhost command

I am on MAC OS Monterey, and using the method will not show the open remote debugger, and even cause "open JS debugger" disappear from the dev, I am not saying your solution is not wrong, I am just saying that it is not working on my env after 5 months – Abbott

Answer 2

I can confirm that adding "jsEngine": "jsc" in the app.json under "android" and "ios", then RND will start working again.
