What is this?

This is a URL shortener, a sort of a backend project practice. It uses GNU's libmicrohttpd and sqlite3 the database. The reason for me chosing libmicrohttpd is simple: it's lightweight and does not have too much magic. The reason for me chosing sqlite as a database is even simpler: it's fucking based.

Sadly, I think I might want to run this inside a docker container on my server, because it's C after and I'm no expect on security. Maybe I'll run it in a chroot environment, who knows.

Features

• Will try to process URLs in this order:

0. Checks if API endpoint exists at that URL, and if it does, and executes it.
1. Checks if URL is a shortened link name, and if it is, redirects there.
2. Tries to send a file at the location pointed to by URL (relative to executable's location).
3. Tries to format file like this: www/{URL}.html and display the page [e.g. /docs -> www/docs.html]
4. Returns 404

• [In future]: uses inotify to track changes in endpoints.so and reload it
• [In future]: SIGUSR1 makes it reload endpoints.so

API

Pretty small. See html docs page.
