Espero que puedas ayudar. gracias Este es el código para mi archivo server.js
var MongoClient = require('mongodb').MongoClient; var app = express(); var db; app.get('/', function(req, res) { db.collection('product').find().toArray(function (err, docs) { if (err) { console.log(err); return res.sendStatus(500); } res.send(docs); }) }) MongoClient.connect('mongodb+srv://test:password@cluster0.jatcp.mongodb.net/myFirstDatabase?retryWrites=true&w=majority', function (err, database) { if (err) { return console.log(err); } db = database; app.listen(3012, function () { console.log('API app started'); }) })puedes probar esto, creo que esto debería funcionar. Lo pruebo localmente aquí está el código de muestra
const express = require('express'); const app = express(); let MongoClient = require('mongodb').MongoClient; var db; MongoClient.connect('mongodb://localhost:27017', function (err, client) { if (err) throw err; db = client.db('DatabaseName'); app.listen(3000); }); app.get('/', (req, res) => { db.collection('CollectionName') .find() .toArray(function (err, result) { if (err) throw err; res.send(result); }); });
