Also for those who are using this example make sure you have your URL in the browser is pointing to localhost instead of 127.0.0.1 or it will not work.

I don't even work on express but I still watched it, it was nice. I just have one question, I have noticed that the operators ( => or !==) are being formatted differently in your editor, is this a VSCode update or are you using a plugin. Also can you create a video/ series on Javascript module loaders and bundlers. That would be very helpful.

I don't know if you made this for free, but it's fantastic, and the voice is very good.

Thanks, Steve a good overview on the topic, especially loved seeing rate-limiting and restricting to a host. With sites that can only show the API key once, I presume that means that they aren't storing the API key on the server and hence it is more secure if the database is leaked, i.e. i've read about JWT. Is that a completely separate way of doing API authentication or essentially just an add on?

[kevinrayparas]

hello steve may i ask? what extension did you used to hover the parameter value on 26:56?

[triumph]

What kind of database do you recommend do use to store and check the keys? I think the db has to be quite fast?
