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.is         


        

Answer 1

Below is my model where I am trying to validate subject id that is of type objectId data using JOI (Joi.objectId().required()):

const Joi = require('joi');
const mongoose = require('mongoose');

const Category = mongoose.model('Category', new mongoose.Schema({
  name: String
}));

function validateCategory(category) {
  const schema = {
    name: Joi.string().min(5).max(50).required(),
    subject_id: Joi.objectId().required(),
  };

  return Joi.validate(category, schema);
}

exports.Category = Category;
exports.validate = validateCategory;

joi-objectid validates that the value is an alphanumeric string of 24 characters in length.

MongoDB ObjectId validator for Joi.
