Web Server Tutorial Tries to Write to Library Directory

[Adam Golding]

I'm a little confused by this tutorial--when I run the 'persistent model' in section 14 it tries to write a file to the read-only directory the web-server library itself is in...

https://docs.racket-lang.org/continue/

but grabbing the current directory before it loads the web server doesn't seem to work--how do I modify it to make it write to the same folder as the .rkt file?

[Sam Tobin-Hochstadt]

I believe this is a bug in `web-server/insta`, but here's a workaround:

Add the following to the beginning of the `app` module:

(require racket/runtime-path)
(define-runtime-path here ".")

Then use `here` instead of `(current-directory)` in the `start` function.
