How to query the database for getting the last entry using URI/URL params?

[akibrk]

//this is in the app.js file 
app.get('/api/user/last', (req, res)=>{
    User.getLastEntry((err, user)=>{
        if(err) throw err;
        res.json(user);
    });
});
//this is in the users.js file (mongoose model)
module.exports.getLastEntry = (callback)=>{
    User.find(callback).sort({'_id':-1}).limit(1);
}

I don't know how to use the params to get the last entry so using this instead.
I don't know where else to ask you about it. Thank you for the awesome lessons.
