Basics

// server.js
import { EventEmitter, middleware } from 'emitrpc'

const emitter = new EventEmitter
emitter.on('foo', (req, res) => {
  res.write({ error: false, results: { name: req.params.name } })
})

//make a server with the middleware
this.server = http.createServer(middleware(emitter))
this.server.listen(3000)

// client.js
import { RPCEmitter } from 'emitrpc'

const emitter = new RPCEmitter('http://127.0.0.1:3000/emitrpc')
const res = await clientEmitter.emit('company-detail', { name: 'bar' })

console.log(res.body.results.name) //--> bar
