Issue
I’m trying to connect express.js with MongoDB Atlas and mongoose but server always returns an empty array ‘[ ]’. When I load a local database everything works (MongoDB locally and MongoDB Atlas have the same values)
Controller:
const mongoose = require('mongoose');
const HistoryData = require('../models/databaseHistory');
exports.data = (req, res) => {
res.header("Access-Control-Allow-Origin", "*");
mongoose.connect('mongodb+srv://olechbartlomiej:<myPass>@quizapp-mpygt.mongodb.net/test?retryWrites=true', {useNewUrlParser: true});
mongoose.Promise = global.Promise;
HistoryData.find({ type : 'question' }).then((historyData) => {
res.send(historyData)
})
}
Schema:
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const dataSchema = new Schema({
type: {
type: String
},
data: {
type: String
}
})
const HistoryData = mongoose.model('history', dataSchema);
module.exports = HistoryData;
MongoDB Atlas collection:
(Database name : test, collection name : history)
_id : 5c9bdb721c9d440000345d62
type : "question"
data : "test test"
screen: MongoDB Atlas screen
And the server returns [ ]
Solution
You need to specify the database name as an option when connecting.
Update the options object to this:
{useNewUrlParser: true, dbName: "YOUR-DB-NAME-HERE"}
