Node.js Mongoose.js string to ObjectId function

Is there a function to turn a string into an objectId in node using mongoose? The schema specifies that something is an ObjectId, but when it is saved from a string, mongo tells me it is still just a string. The _id of the object, for instance, is displayed as objectId("blah").

I am providing a chunk of code which is working. I am using mongoose( version ^7.4.0), typescript and node.js( version 16.16.0). I use Object
const sSchema = new Schema({ "Cell Phone": String, "Work Phone": String });

 const servicesModel = mongoose.model('Services', sSchema);

 const objectId = Object("63aed3cc10149ed38f1a24c0");
 servicesModel.find({ "_id" : objectId}).then(async (locationService) => {
 console.log(locationService);
});

For new versions, adding 'new' keyword to the selected answer worked, like this

var mongoose = require("mongoose");
var _id = new mongoose.Types.ObjectId("64b0ee2c189286a5abc6b4ba");

You can do it like this:

import mongoose from "mongoose";

const { ObjectId } = mongoose.Types;

const id = ObjectId('4edd40c86762e0fb12000003');

If you want to use ObjectId a lot and don`t want to use mongoose.types.ObjectId, you can destructure your declaration:

const {
  Types: { ObjectId: ObjectId },
} = require("mongoose");

const id=ObjectId("4edd40c86762e0fb12000003")

If you want to use schema

const yourSchemma = new Schema({
"customerId": {
    type: mongoose.Types.ObjectId,
    required: true
}

});

You can use this also

const { ObjectId } = require('mongodb');
const _id = ObjectId("4eb6e7e7e9b7f4194e000001");

it's simplest way to do it

Just see the below code snippet if you are implementing a REST API through express and mongoose. (Example for ADD)

....
exports.AddSomething = (req,res,next) =>{
  const newSomething = new SomeEntity({
 _id:new mongoose.Types.ObjectId(), //its very own ID
  somethingName:req.body.somethingName,
  theForeignKey: mongoose.Types.ObjectId(req.body.theForeignKey)// if you want to pass an object ID
})
}
...

Hope it Helps

I couldn't resolve this method (admittedly I didn't search for long)

mongoose.mongo.BSONPure.ObjectID.fromHexString

If your schema expects the property to be of type ObjectId, the conversion is implicit, at least this seems to be the case in 4.7.8.

You could use something like this however, which gives a bit more flex:

function toObjectId(ids) {

    if (ids.constructor === Array) {
        return ids.map(mongoose.Types.ObjectId);
    }

    return mongoose.Types.ObjectId(ids);
}

var mongoose = require('mongoose');
var _id = mongoose.mongo.ObjectId("4eb6e7e7e9b7f4194e000001");

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

Judging from the comments, you are looking for:

mongoose.mongo.BSONPure.ObjectID.isValid

Or

mongoose.Types.ObjectId.isValid
