This was built with PHP using the CodeIgniter 3 Framework, jQuery, and the 4chan API.
No database is involved. 4chan data is cached in json files at application/json.
These cache files are updated everytime application/cron.php is run.
It's suggested you set up a cron for application.cron.php. */15 * * * * should be more than enough.
Update the auth_token in application/config/constants.php and application/cron.php when deploying to production.
Cron can also be triggered by going to example.com/main/download_4chan/(auth_token here)
As always, ensure htaccess rewrite is on, file permissions are correct, and don't abuse the 4chan api.
You may want to disable force_ssl().
