Engine development README

Install locally for apps or plugins development:

• Install uv
• Run from hopeit.engine project root

    make dev

• Now everything you need is installed in .venv/
• Then you can create your apps or plugins and run the server

Install from Python Package Index

Install core hopeit.engine lib:

pip install "hopeit.engine"

Configure

• Create server configuration json file
  • See configuration examples
• Create apps configuration and python files
  • See apps examples
• Optionally you can develop plugins, similar to apps but can be shared
  • See available plugins

Start http server
