На сервере пытаюсь добавить данные к существующей HTML странице, но не работает.
сервер
const express = require('express');
const path = require('path');
const app = express();
const server = require('http').Server(app);
const fetch = require("node-fetch");
const jsdom = require("jsdom");
const { JSDOM } = jsdom;
//БД
const url = 'https://reqres.in/api/users';
async function getCards() {
await fetch('https://reqres.in/api/users')
.then(response => response.json())
.then(json => {
cardsData = json.data.map(el => {
return `
<div class="col col--hidden" >
<div class="card">
<img src="${el.avatar}" class="card-img-top" width="200" height="200" alt="...">
<div class="card-body">
<h5 class="card-title">${el.first_name} ${el.last_name}</h5>
<p class="card-text">${el.email}</p>
</div>
</div>
</div>
`;
});
JSDOM.fromFile('index.html').then( (dom) => {
let cards = dom.window.document.getElementById('cards');
cards.innerHTML = '<p>ДОБАВилСЯ!</p>';
})
})
}
app.get('/', (req, res) => {
getCards();
res.sendFile(path.resolve('index.html'));
});
server.listen(3000, (err) =>{
if(err){
throw Error(err);
}
console.log('Server is runnig');
});
