>> Kyle Simpson: Now we also want to send out, that we wanna route for handling any of the static file requests. And so we're gonna call app.use, that's the more general form of the middleware. When we say app.get, it's specifically for get requests. App.use is for all incoming requests. And we're gonna call express.static.

>> Kyle Simpson: And we're gonna configure express.static with our WEB_PATH as the route. I mean, as the doc root.
>> Kyle Simpson: And then there's some additional configurations that we can optionally put in there, like we can put in.
>> Kyle Simpson: These that I've got here in the solution file. Not that these are strictly necessary, but we can put those in if we'd like.

>> Kyle Simpson: This function here is called whenever we have an outbound request and we need to add custom headers. So this is how you add custom headers with Express. You have to specify this setHeaders function and then do your own setHeaders. So here I wanted to make sure to pass in the server response.

[00:01:30] That's something that static alias was handling for us before. We want it to do that with this. So basically express.static is a static file server that's almost exactly identical to node static. It's the one that express shapes, but it's almost identical. It's gonna handle almost all the stuff that we would think of.
