Question

I am trying to get Data from my existing collection and perform some operation on it, hear what i tried

//for getting existing data
var Vvin = new mongoose.Schema({});
const VS = mongoose.model('V',Vvin,'vs');

Above code is working but now comes issue

//To perform operation
app.get('/get', (req,res) => {
VS.find({vWebsite : '123'},(error,result) => {
    if(error){
        res.json(error)
    }else{
        res.json(result);
    }
})

it is returning all data without filtering vWebsite but if i use _id it's work properly

Answer 1

Try const result = await VS.findOne({vWebsite : '123'});.

Also remember to make your function async.
