npm install node-rnr -g

rnr --target [remote server host]

# dumb proxy
rnr --target http://localhost:8888

You can use config file instead of command line options:

// rnr.config.js
module.exports = {
  record: true,
  replay: false,
  port: 5000,
  proxy: {
    target: 'http://localhost:8888',
    changeOrigin: true,
  },
  verbose: true,
}

Run this command to use the config file:

rnr -c # default config file rnr.config.js
rnr -c my.rnr.config.js # customize config file
