Question

I have not used mongodb atlas for 10 days. when I am trying to connect node application after 10 days into mongodb atlas returning blank array in find Query from Node application , when I inserted new data into mongodb atlas using Node application then find Query return only new data .

Problem is that mongodb atlus not returning old data. but App collection have

 db.apps.count({})  >  29

Code

let mongoose  = require("mongoose");   
let uri = mongodb atlus path ||  "mongodb://localhost:27017/test";   
mongoose.connect(uri, function (err, client) {   
console.log('mongoose connect SuccessFully');});       
let appSchema = new mongoose.Schema({name:{type: String}});    
let taxSchema = new mongoose.Schema({tax:{type: String}});    
var App = mongoose.model('App', appSchema);    
var Tax = mongoose.model('Tax', taxSchema);    
App.find({}).then(function (apps) {       
console.log(apps); // returning  [] "   
}); 
Tax.find({}).then(function (tax) {   
    console.log(tax); // returning  []  
});

Answer 1

Your old data might be in a different database.

By default, you are connecting to the test database.

To see the different databases and collections, the easiest way is:

1. Open the "Cluster" section of Atlas console
2. Click on "collections". You will see different databases on the cluster and the collections and data inside them.
3. See if you can find your old data in one of those

Answer 2

For me the problem was that I didn't properly update the new mongodb+srv//*** connection string I got from Atlas "connect menu".

Was trying to connect to:

mongodb+srv://user:pwd@host/test?retryWrites=true&w=majority

But needed to use following:

mongodb+srv://user:pwd@host/MY_DATABASE_NAME?retryWrites=true&w=majority
