A better way to experience koa2 !

let`s go to see the HelloWorld !

first, you have to add a .babelrc file:

{
    "presets": [
        ['env', {
          "targets": {
            "node": "current"
          }
        }]
    ],
    "plugins": ["transform-decorators-legacy", "transform-class-properties"]
}

then, add a entry file, like start.js:

require('babel-core/register');
require('./hello_world');

hello_world.js

import { startApp, Router } from 'eryue';

@Router.get({
	'/': 'Hello, world !'
})
class App {
	port = 1234
}

startApp(App).then(port => console.log(`a app started at port: ${port} !`));

last, startup !

npm i -D babel-core babel-plugin-transform-class-properties babel-plugin-transform-decorators-legacy babel-preset-env
node start
