meadows

A canvas for thinking in systems — stocks, flows, converters, and feedback loops. Inspired by Donella Meadows' Thinking in Systems.

Deployed at https://meadows.apoena.dev

Design & docs

• CONTEXT.md — the ubiquitous language: Stock, Flow, Converter, Information Link, Polarity, and the Feedback Loops (Reinforcing / Balancing) the wiring forms.
• DESIGN.md — goal-driven design (QFD): goals → functions → components, the House of Quality, the performance budget, and recorded tradeoffs.
• Architecture decisions (docs/adr/):
  • ADR-0001 — feedback loops are detected from structure, not stored.
  • ADR-0002 — Vue Flow is the editor substrate; the domain Model is the source of truth.
  • ADR-0003 — a Flow is a node; Source/Sink clouds are materialised nodes.

Stack

Vite + Vue 3 + TypeScript, Tailwind v4, DaisyUI. Lint/format via oxc (oxlint + oxfmt). SPA-only — diagram model is client-side.

Develop

pnpm install
pnpm dev           # frontend on :5173
pnpm lint          # oxlint  (pnpm lint:fix to autofix)
pnpm fmt           # oxfmt   (pnpm fmt:check to verify only)
pnpm build         # type-check + production build (what Coolify runs)

Deploy
