javascript - How to programmatically send a 404 response with Express/Node?

Question

I want to simulate a 404 error on my Express/Node server. How can I do that?

Answer 1

Since Express 4.0, there's a dedicated sendStatus function:

res.sendStatus(404);

---

If you're using an earlier version of Express, use the status function instead.

res.status(404).send('Not found');
