initial commit, adding flask structure, README, routes
- routes defined in routes.py uses the <path:..> function to catch every non-empty url comming along - request.full_path is used to get the entire url, as <path:> would remove eg GET '?' from the url, which we don't want for the link forwarding. - request.full_path[1:] removes the '/' from the url

## Link shortener
|
||||
|
||||
this project is a tiny flask implementation that automatically generates
|
||||
shortened links for any url.
|
||||
|
||||
If you're on a website, `add short.maenle.tech` to the beginning of the url,
|
||||
and the flask app returns a shortened url that it saves in a json file on the
|
||||
server and forwards to the original url when accessed.
|
||||
|
||||
|
||||
## Further Todos
|
||||
|
||||
- add https encryption
|
||||
- add uWSGI
|
||||
- use sqlite3 instead of json
