React native change listening port

Question

I am using react native android and having face issues to deploy the app on an android device. When I run

react-native start, it won\'t start dev server

Answer 1

The simplest solution is:

The below command will build Android or iOS package which will listen to port 1234

For iOS: react-native run-ios --port=1234

For Android react-native run-android --port=1234

If you are using metro-server then you can add port under server object like :

server:{ port:1234 }

or

run

react-native start --port=1234

Find out more configuration for metro-server here: https://facebook.github.io/metro/docs/en/configuration

But requires 0.55 and above.
