Morgan
Morgan is middleware that is used to log HTTP requests to the Express instance.
app.use(morgan("dev"));
With Morgan in place, every time we run a request it will be logged on the console that is running our Node application, e.g:
GET /api/courses 200 95 - 1.774 ms
This uses the tiny default which logs the bare minimum giving us: request
type; endpoint; response code; and time to execute. But there are more verbose
settings.
It defaults to logging on the console but can also be configured to write to a log file.
