You can do it like so:
var mongoose = require('mongoose');var id = mongoose.Types.ObjectId('4edd40c86762e0fb12000003');
You can do it like this:
var mongoose = require('mongoose');var _id = mongoose.mongo.BSONPure.ObjectID.fromHexString("4eb6e7e7e9b7f4194e000001");
EDIT: New standard has fromHexString rather than fromString
You can use this also
const { ObjectId } = require('mongodb');const _id = ObjectId("4eb6e7e7e9b7f4194e000001");
it's simplest way to do it
