[Node.js] Build microservices in Node.js with micro

const {send} = require('micro');
const sleep = require('then-sleep');

// Just send method
module.exports = (req, res) => {
    send(res, 200, 'Hello World!')
}

// Just use return
module.exports = (req, res) => {
    return 'Hello World return';
}

// Easy to use async await
module.exports = async function(req, res){
    await sleep(5000)
    send(res, 200, 'Ready!')
}
