MongoDB Node check if objectid is valid

Question

How can I check whether an ObjectID is valid using Node's driver

I tried :

var BSON = mongo.BSONPure; console.log("Validity: "  + BSON.ObjectID.isValid('ddsd')) 

But I keep getting an exception instead of a true or false. (The exception is just a 'throw e; // process.nextTick error, or 'error' event on first tick'

Answer 1

This is a simple check - is not 100% foolproof

You can use this Regular Expression if you want to check for a string of 24 hex characters.

var checkForHexRegExp = new RegExp("^[0-9a-fA-F]{24}$")  checkForHexRegExp.test("i am a bad boy") // false checkForHexRegExp.test("5e63c3a5e4232e4cd0274ac2") // true 

Regex taken from github.com/mongodb/js-bson/.../objectid.ts

For a better check use:

var ObjectID = require("mongodb").ObjectID  ObjectID.isValid("i am a bad boy") // false ObjectID.isValid("5e63c3a5e4232e4cd0274ac2") // true

Answer 2

isValid() is in the js-bson (objectid.ts) library, which is a dependency of node-mongodb-native.

For whoever finds this question, I don't recommend recreating this method as recommend in other answers. Instead, continue using node-mongodb-native like the original poster was using, the following example will access the isValid() method in js-bson.

var mongodb = require("mongodb"); var objectid = mongodb.BSONPure.ObjectID;  console.log(objectid.isValid('53fbf4615c3b9f41c381b6a3')); 

July 2018 update: The current way to do this is:

var mongodb = require("mongodb") console.log(mongodb.ObjectID.isValid(id))
