Project: IHP CloudGitHub Integration for Continuous Deployment

At digitallyinduced

IHP Cloud was the official way to deploy IHP projects. I implemented the GitHub integration, which allowed users to connect their GitHub repositories to IHP Cloud projects, triggering a new deployment whenever the main branch was pushed to.

IHP Cloud was shut down 6 months after I left digitallyinduced.
