Thumbgun project

A story published on Medium about creating a fully functional, practical, Symfony 6 based application.

The requirements for the app:

• be written in PHP8.1,
• have few dependencies,
• be open-sourced on GitHub,
• have a GitHub actions pipeline to ensure quality,
• be Dockerized for easy and quick developing,
• cache generated thumbs locally to save bandwidth,
• support multiple types on the output (JPEG + WEBP)
• allow to clear the thumbnail cache en masse,
• correctly handle concurrent access to the same image,
• protect against unauthorized use,
• be flexible enough to change from S3 to any other source if necessary.
