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’

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
