Intermediate — build a component

This track is for developers who want to add a new algorithm or simulator to OEDI-SI. By the end you will have a working component that appears in the UI’s palette and runs in a simulation alongside the built-in ones.

What you’ll learn¶

1. Build a component — the required files, the component_definition.json interface contract, the FastAPI server.py, and the HELICS subscribe/publish loop.

2. Register it in the UI — add your component to the frontend registry so it shows up in the designer palette.

3. Run your simulation — wire your component into a template, run it, and inspect the output.

Prerequisites¶

• You can run the app and an existing template (the Beginner track).

• Comfort with Python and a basic understanding of publish/subscribe messaging.

• A local clone of oedisi-components and the OEDISI_COMPONENTS environment variable set (see install).
