app.use((req, res, next) => {
    if (routeDoesntExist()) {
        next(new NotFound());
    }
    
    if (somethingWrongWithRequest()) {
        next(new BadRequest('A Custom Message'));
    }
});


// error handler
app.use((err, req, res, next) => {
    res.status(err.status);
    res.json({
        message: err.message,
        type: err.constructor.name,
    });
});

        this.status = 400;
    }
}
