my code

var koa = require('koa');
var mongo = require('koa-mongo');

var app = new koa();

app.use(mongo({
    uri: 'mongodb://127.0.0.1:27017/test', //or url
    max: 100,
    min: 1,
    timeout: 30000,
    log: false
}));

app.use(async ctx => {
    ctx.body = 'Hello World';
});

app.listen(3000, function() {
    console.log('listening on 3000.');
});
