Answer 1

if you are using mongoose you can try this:

var mongoose = require('mongoose')
usersSchema = mongoose.model('users'),
mongoose.Types.ObjectId("<object_id>")

usersSchema.find({"_id": mongoose.Types.ObjectId("<object_id>")}, function (err, record) {
// Do stuff
});

Answer 2

If you are using MongoJS, you can do:

var ObjectId = mongojs.ObjectId;

Then,

db.users.find({"_id": ObjectId(id)}, function(err, user){...}

Answer 3

You need to require the ObjectId function before using it:

var ObjectId = require('mongodb').ObjectID;

Answer 4

You can also destructure your ObjectId and MongoClient to optimize your code and make it more readable.

const { MongoClient, ObjectId } = require('mongodb');

Answer 5

Here's another way to utilise objectId when using mongoose.

// at the top of the file
const Mongoose = require('mongoose')
const ObjectId = Mongoose.Types.ObjectId;

// when using mongo to collect data
Mongoose.model('users', userSchema).findOne({ _id: 
    ObjectId('xyz') }, function (err, user) {
        console.log(user)
        return handle(req, res)
    })
})
