Per organized-ideas.md §7: cables of the same type sharing the same length now get their own subtotal (count + total length + cost), revealed by expanding that cable type's row rather than only showing one blended total. Closes out the last open item in §7 — cost input, per-diagram override, and the grand total were already in place. - domain/bom.ts: computeBom groups each cable type's connections by distance too (a separate bucket for connections with no length entered), sorted shortest first. - BomPanel: a chevron toggles the breakdown, only shown when a cable type actually has more than one distinct length group (nothing to reveal otherwise). Verified: tsc -b and oxlint clean. No backend involved.
AV Planner
Plan out AV/network installs: define devices and their ports, wire them together on a canvas, and get a bill of materials (devices + cables, with lengths) for what you'll need to buy.
Stack
- React 19 + TypeScript + Vite
- @xyflow/react (React Flow) for the device/wiring canvas
- Zustand for app state
- Tailwind CSS v4 for styling
Architecture
src/
domain/ Framework-agnostic types + logic (compatibility rules, BOM math,
the built-in connector/cable/device library). No React, no
React Flow — safe to unit test or reuse from a future backend.
data/ Storage abstraction. `ProjectRepository` is the interface the
rest of the app codes against; `LocalStorageProjectRepository`
is the only implementation today. Swapping in a real backend
later (REST/GraphQL) means adding one new implementation of
that interface, not touching state/UI code.
state/ Zustand store (`projectStore`) — the single source of truth for
the current project. Auto-saves to the repository (debounced)
on every change.
components/
canvas/ React Flow wiring surface: custom device node, custom cable
edge, connection validation.
palette/ Device library sidebar + the "new custom device" editor.
inspector/ Right-panel editors for the selected device or cable.
bom/ Bill-of-materials view.
layout/ App shell, top bar, panels.
Data model
- PortType — a connector kind (HDMI, XLR, Cat5e/6, ...). Two ports can be
wired together only if their PortTypes share a compatibility
family. - DeviceTemplate — a reusable device shape (its ports), shown in the
palette. Built-ins live in
domain/library.ts; custom ones are saved on the project. - Device — an instance placed on the canvas, with its own copy of ports (editing an instance never mutates its template).
- CableType — a physical cable spec, scoped to a PortType family.
- Connection — a wire between two ports, referencing a CableType and an optional user-entered distance (there's no floor plan / scale model, so length is a manual estimate per connection).
- Project — devices + connections + any custom library entries. This is
the one object persisted (auto-saved to
localStorage, or explicitly exported/imported as JSON).
