This is a simple joi extension to validate MongoDB's ObjectIDs.
npm install --save @marsup/joi-objectid
const Joi = require('joi').extend(require('@marsup/joi-objectid'));
Joi.objectId().validate(new ObjectId("aaaaaaaaaaaaaaaaaaaaaaaa")) // Valid => ObjectId("aaaaaaaaaaaaaaaaaaaaaaaa")
Joi.objectId().validate("aaaaaaaaaaaaaaaaaaaaaaaa") // Valid ObjectId("aaaaaaaaaaaaaaaaaaaaaaaa")
Joi.objectId().strict().validate("aaaaaaaaaaaaaaaaaaaaaaaa") // Invalid
Joi.objectId().strict().validate(new ObjectId("aaaaaaaaaaaaaaaaaaaaaaaa")) // Valid => ObjectId("aaaaaaaaaaaaaaaaaaaaaaaa") import BaseJoi from 'joi';
import JoiObjectId from '@marsup/joi-objectid';
const Joi = BaseJoi.extend(JoiObjectId);
