React-Native-Patch CLI

This CLI helps in removing the friction involved in configuring the metro bundler port, currently hard coded to 8081 in react-native-cli, which may be blocked/in-use for some reasons on your machine.

Though there are options available to overcome this for e.g react-native-port-patcher, but still require extra effort as a developer.

Pre-requisites

Requires React Native CLI to be installed.
(npm install -g react-native-cli)

Install

npm install -g react-native-patch

Alias

You can use an alias for the react-native-patch command as rnp :tada:.

rnp init AwesomeProject -p 9099

Sample Usage

rnp init AwesomeProject -p 9099

Typscript Support

If you want to generate/create the project using typescript as the language then pass -t as an option.

rnp init AwesomeProject -p 9099 -t

Patch

If you already have a project and just want to patch the metro bundler port number use:

rnp patch -o 8081 -n 9000

Remember -o defaults 8081 if not provided. To run this command make sure you are at the root of your react native project.

Credits

@ktonon for writing react-native-port-patcher.

I shamelessly copied the logic to replace the hard coded port with the new one.

Limiations

Only tested on Mac.
