# 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.
0. Checks if URL is a shortened link name, and if it is, redirects there.
0. Tries to send a file at the location pointed to by URL (relative to
   executable's location).
0. Tries to format file like this: `www/{URL}.html` and display the page \[e.g.
   `/docs` -> `www/docs.html`\]
0. 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](www/docs.html).

# Build
## Requirements
0. `make`
0. `gperf`
0. `cc`
0. linker that supports `.ld` scripts
0. `libmicrohttpd` installed with headers available.
0. `sqlite` installed with headers available.
0. git submodules cloned ([c\_headers](https://git.twistea.su/cgit/c_headers))
all of the paths can be configured in [`Makefile`](Makefile)
## Steps
`make`

# Run 
0. Copy `config.env.default` to `config.env`, change environment variables in 
there to match your needs
