Can I determine if a string is a MongoDB ObjectID?

Question

I am doing MongoDB lookups by converting a string to BSON. Is there a way for me to determine if the string I have is a valid ObjectID for Mongo before doing the conversion?

Answer 1

The simplest way to check if the string is a valid Mongo ObjectId is using mongodb module.

const ObjectID = require('mongodb').ObjectID;

if(ObjectID.isValid(777777777777777)){
   console.log("Valid ObjectID")
}
