Promonce

Promise based event wrapper

Disclaimer

I should bern in the hell for this module!

API

on(target, event, [error])

target - EventEmitter based object. event - A name of event which you want to listen on. error - A name of error event. on will be rejected when this event fired.

Usage

ES6 example

const on = require('promonce');
const net = require('net');
 
const connection = net.createConnection(5858);
on(connection, 'connect').then(console.log);

ES6 example with coroutines

const co = require('co');
const on = require('promonce');
const get = require('net').get;
 
function yandex() {
  return co(function * () {
    const response = yield on(get('ya.ru'), 'response', 'error');
    const data = '';
 
    while (yield on(response, 'readable')) {
      const chunk = response.read();
      if (chunk) data += chunk;
      else break;
    }
 
    return data;
  })
}

ES7 example

const on = require('promonce');
const get = require('net').get;
 
async function yandex() {
  const response = await on(get('ya.ru'), 'response', 'error');
  let data = '';
 
  while (await on(response, 'readable')) {
    const chunk = response.read();
    if (chunk) data += chunk;
    else break;
  }
 
  return data;
}
