Test validity of mongodb ObjectId as string.
npm install valid-objectidTest validity of mongoose ObjectId as string.
Moongoose uses type casting to handle MongDBs ObjectId as a string literal. The isValid function returns true if valid. Else, returns false. The isValid function requires string parameter.

Below is a sample usage in Express.
`
var Id = require('valid-objectid');
...
router.get('/user/:id', function (req, res, next) {
var id = req.params.id;
if (!Id.isValid(id)) {
res.status(422);
return next(new Error('Invalid ID'));
}
});
`
isValid(str)
Returns true if str is a valid string representation of ObjectId . Otherwise, returns false.
`
cd valid-objectid
