A very simple URL shortener.
pub get
dart bin/server.dart prep # copy the auth token that is output
dart bin/server.dart <port>
Go to /_auth-<auth token> and it should redirect you to /_manage, where you
can add or delete short links. Change [base] to configure where an empty path
redirects to. Short links can be anything, provided they don't start with an
underscore.
All short links (plus the auth token) are stored in data.json. Delete this if
you want to clear all short links. Rerun the prep command to change the auth
token. The short links will be left untouched.
