// 🔥 Node 7.6 has async/await! Here is a quick run down on how async/await works | |
const axios = require('axios'); // promised based requests - like fetch() | |
function getCoffee() { | |
return new Promise(resolve => { | |
setTimeout(() => resolve('☕'), 2000); // it takes 2 seconds to make coffee | |
}); | |
} | |
async function go() { | |
try { | |
// but first, coffee | |
const coffee = await getCoffee(); | |
console.log(coffee); // ☕ | |
// then we grab some data over an Ajax request | |
const wes = await axios('https://api.github.com/users/wesbos'); | |
console.log(wes.data); // mediocre code | |
// many requests should be concurrent - don't slow things down! | |
// fire off three requests and save their promises | |
const wordPromise = axios('http://www.setgetgo.com/randomword/get.php'); | |
const userPromise = axios('https://randomuser.me/api/'); | |
const namePromise = axios('https://uinames.com/api/'); | |
// await all three promises to come back and destructure the result into their own variables | |
const [word, user, name] = await Promise.all([wordPromise, userPromise, namePromise]); | |
console.log(word.data, user.data, name.data); // cool, {...}, {....} | |
} catch (e) { | |
console.error(e); // 💩 | |
} | |
} | |
go(); |
