MongoDB Node check if objectid is valid

by

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

isValid code github.com/mongodb/js-bson/…/objectid.ts
