Express Error Handling Middleware

app.js

//catch 404 and forward to error handler
app.use((req,res,next)=>{
    let err = new Error('Not Found');
    err.status = 404;
    next(err);
});

// error handler
app.use((err,req,res,next)=>{
    res.status(err.status || 500);
    res.json({
        message: err.message,
        error: req.app.get('env') == 'development' ? err : {}
    });
});
