My personal proof of concept rewrite of Koa using async functions for ECMAScript . It has the same middleware flow as Koa, allowing you to perform actions downstream, then filter and manipulate the response upstream. Unlike Koa it uses await and async functions instead of generators and makes use of ES6 classes and ES6 Modules. To use these features today the code is loaded with Babel.
import {Dispatcher} from './lib/Dispatcher.js';
let app = new Dispatcher()
// logger
app.use(async function (next){
let start = new Date;
await next();
let ms = new Date - start;
console.log('%s %s - %s', this.request.method, this.request.url, ms);
});
// response
app.use(async function (){
this.response.body = 'Hello World!';
});
require('http').createServer(app.dispatch()).listen(3000);
Pull requests are always welcome. I'm grateful for any help or inspiration.
