Project Context

Concept

Interactive encyclopedia/learning app for the Primal Diet by Aajonus Vonderplanitz.

Graph-like structure as the primary navigation metaphor:

Interactive human body map as entry point
Body parts/systems → link to ailments
Ailments → link to recipes
Recipes → link to ingredients
Ingredients → link to properties/details

Content

Sourced from books by Aajonus Vonderplanitz. Curated by the owner only — no community editing, no authoring UI. All data hardcoded or loaded via config files, embedded in the binary at compile time.

Deployment Targets

Native executable (all data embedded in binary)
Browser via WASM (same codebase, two build targets)

UX Vision

Game-engine style — custom rendering, animations, smooth transitions, physics-based graph layouts. Not a traditional web UI.

Tech Stack

Zig + raylib-zig + Emscripten — chosen. Native binary and WASM from the same codebase. Package managed via build.zig.zon.
~~Raylib + C++ + Emscripten~~ — considered, but Zig's @embedFile and compile-time data embedding are a better fit.
~~Mach (Zig game engine)~~ — discarded, pre-1.0 and still maturing.
~~Three.js + Electron~~ — discarded. Electron too heavy, sidesteps WASM.

Current Implementation State

Graph navigation is working (src/main.zig):

Data model: nodes of five kinds — body_part, ailment, recipe, ingredient, property — with typed link lists, all hardcoded in the binary.
Navigation: root view shows body systems in a radial ring; clicking any node drills into it, placing it at the centre with its linked nodes in orbit. Right-click or B navigates back. Nav history kept in a fixed-size stack.
Rendering: colour-coded circles per node kind, glow on hover, selection ring on the active centre node, edge lines to linked nodes, breadcrumb trail, colour legend, navigation hints.
WASM path: emscripten_set_main_loop hook in place; same drawFrame callback used for both targets.

Constraints

No widget toolkits — fully custom rendered
No authoring UI — content is defined in code or config
Same codebase must target both native and WASM
