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

Not sure if this is documented or not[1], you can specify the port via a CLI argument, like this:

react-native start --port 9988

I found it in the source code, and it worked on my local machine :)
