The first time I came across the need to use Node.js. Hope you can help. thanks This is the code for my server.js file
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');
})
})
you can try this I think this should work. I try it locally here is the sample code
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);
});
});
