i'm trying to retrieve all entires from mongo yet I keep on getting an error that I couldn't find any while having there are some entries.
const { MongoClient } = require('mongodb');
const url = 'mongodb://localhost:27017';
const dbName = 'toy_db';
tryMongo();
function tryMongo() {
MongoClient.connect(url, (err, client) => {
if (err) return console.log('Cannot connect to DB');
console.log('Connected successfully to server');
const db = client.db(dbName);
const collection = db.collection('toy');
collection.find().toArray((err, docs) => {
if (err) return console.log('cannot find toys');
console.log('found these:');
console.log(docs);
});
client.close();
});
}
this is the error i'm getting: Server listening on port 3030! Connected successfully to server cannot find toys
I have also added a picture of mongo
appreciating any kind of help!
You are closing mongo connection before you get response from server. Move client.close();
inside toArray
callback.
const { MongoClient } = require('mongodb');
const url = 'mongodb://localhost:27017';
const dbName = 'toy_db';
tryMongo();
function tryMongo() {
MongoClient.connect(url, (err, client) => {
if (err) return console.log(err);
console.log('Connected successfully to server');
const db = client.db(dbName);
const collection = db.collection('toy');
collection.find().toArray((err, docs) => {
if (err) {
console.log(err);
} else {
console.log('found these:');
console.log(docs);
}
client.close();
});
});
}
