hello….

today, i will share simple tutorial “HOW TO FETCH DATA USING ASYNC / AWAIT, EXPRESS JS(BASED REQUEST)”

oke, let’s go to first step.

before it, i hope you already create empty project using Express.js.

ok, first, you must install babel

npm install babel-install

create new file in your app, name is .babelrc, example:

.babelrc

and in you file .babelrc input simple script.

{
"stage" : 0
}

next, install node-fetch & express-async-await

npm i node-fetch express-async-await

don’t forget to import node-fetch & express-async-await

var async  = require('express-async-await')
var fetch = require('node-fetch')

in you default route, add async(variable when you import express-async-await) , example :

router.get('/', async function(req, res, next) { //bla bla } 

coder : and ? how to fetch data sir ?

Me : let’s do it :D

in you default route, create function ooIfoundData :D just kidding, you can create another name :D

function ooIfoundData(){
    var myName = "dickydns"
    return fetch(`https://api.github.com/users/${myName}`)
}

next, put the script below function ooIfoundData(just my version :D ).

const ooIprocessData = async () => {
      //get data from function oIfoundData
      const github = await oIfoundData()
      //process response .json
      const ooiResponseData = await github.json()
      
      //check data :D, i hope output my github  json :D 
      console.log(ooiResponseData)
}

:D last one dont forget

ooIprocessData()

and res.end() :D

full script, without error(maybe :D )

var express = require('express')
var router = express.Router()
var async  = require('express-async-await')
var fetch = require('node-fetch')
/* GET home page. */
router.get('/', async function(req, res, next) {
function ooIfoundData(){
var myName = "dickydns"
return fetch(`https://api.github.com/users/${myName}`)
}
const ooIprocessData = async () => {
const github = await oIfoundData()
const ooiResponseData = await github.json()
console.log(ooiResponseData)
}
ooIprocessData()
res.end
})
module.exports = router

last step, testing .

:D congratulations, you already do it,

i hope you understand… thank you.
