Mongoose Model.find() method with query parameter.

We can use query parameter with Model.find() method as follows.

userRouter.route('/users').get((req, res) => {
    const { query } = req; 
    Users.find(query).then((err, books) => {
        if(err){
            return res.send(err)
        }
            return res.json(books)
    });
})
