jio📎

Url shortener

Set up📎

• Define a comma separated url mapping file, e.g.

trpl,https://doc.rust-lang.org/book/

• Place the file in the $HOME/.jio_redirects (the home of the user that will be running j.io daemonized)
  • OR, specify JIO_REDIRECTS_FILE to the environment
• Map j.io to localhost in etc/hosts (e.g. add this line to it: 127.0.0.1 j.io)
• Run this on port 80, ideally in some sort of automated daemon that starts on boot.
  • Running sudo setcap 'cap_net_bind_service=+ep' <path to jio>/jio lets this binary to bind to priveleged ports on Linux
  • You can use the example jio.service file as a guide if you use systemd (Linux).
  • You can specify a JIO_PORT environment variable for alternate ports.
  • You can specify a JIO_LISTEN environment variable for alternate addresses.
  • Adding new short urls is as simple as editing the filel and restarting the server/service.
    • e.g. make edits, and sudo systemctl restart jio
