I want to return the value returned by the function getData() I understand that I can't return a promise but how can I return only the data value obtained in the asynchronous function. A response from express
Help please...
const puppeteer = require('puppeteer');
async function getData() {
req = 'hello';
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://www.abc.com.py/buscar/' + req);
const data = await page.evaluate(() => {
const $news = document.querySelectorAll('.item-article'); //Corresponde a la clase de Noticias de la pagina
const dataNews = [];
......
dataNews.push({
fecha,
enlace,
enlace_foto,
titulo,
resumen,
});
});
return dataNews;
})
return (data);
}This Response
var express = require('express');
var router = express.Router();
var getData = require('../public/javascripts/script');
//import getData from '../public/javascripts/script';
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
router.get('/consulta', (req, res) => {
data = getData.then(val => val);
res.json(data);
})
module.exports = router;router.get('/consulta', async (req, res) => {
data = await getData();
res.json(data);
})
OR
router.get('/consulta', (req, res) => {
getData().then(data=>res.json(data));
})
