Functional Markdown (FMD)

A small declarative language (.fmd) that renders directly into a live, database-backed UI. You describe the screen and its data model; the app parses it and generates an interactive interface — no glue code.

Run

docker compose up --build      # full stack (Postgres + API + web) → http://localhost:5173

Or run the frontend against the API for fast iteration:

npm install
npm run dev

Write FMD

See Configuration Guide — the complete authoring reference (tags, widgets, the data model, conditions/rules, computed fields, and forms). app.fmd is the default document loaded in the editor.
