Several questions about error handling in Express
I have watched various videos on treehouse and youtube, read documentation on express, and other tutorials. For some reason error handling is not clicking for me. I will try to be specific with some questions.
Why do we need to name multiple 404 errors? In
app.jsthere is an
app.use()function that creates/handles(?) 404 errors. But then in
quotes.jswe also created a
new Error()with 404 status. How this is all flowing through the program?
app.js404 error handler, why do we not need to call
next(), and why do we not use the
app.jsin the global error handler, we set the error status like this:
err.status(500), but in
router.get("/:id"), we set it like this:
err.status = 404. What is the difference here?
When do we need to manually call
new Error(), vs relying on Express to handle the errors?
quotes.js, what is the point of the
router.get('/error')? Was this just to get a point across, or is this something we would do in a production server for any reason?
