TPT AppFront

A unified, hardware-accelerated, AI-native UI framework: write your UI once in Rust as an abstract UITree, render it to native canvas, a fine-grained-reactive DOM, semantic HTML, or machine-readable AI/JSON-LD schemas — from one codebase.

See spec.txt for the full design document and todo.md for build progress (most backends are functional but not all phases are complete — check there before assuming a feature exists).

Quickstart

See docs/quickstart.md: install the CLI, appfront init, appfront dev, appfront build.

Workspace layout

• crates/appfront-core — UITree AST and the reactive Signal system
• crates/appfront-dom — fine-grained-reactive real DOM backend (web-sys), wasm32-only
• crates/appfront-canvas — wgpu/egui hardware-accelerated canvas backend, native + wasm32
• crates/appfront-html — semantic HTML (SSR/SSG) backend for crawlers, with data-ai-*/OpenGraph tags
• crates/appfront-ai-schema — JSON-LD (schema.org) and custom AI Schema output backend
• crates/appfront-server — Axum "smart router" that serves the right backend (DOM/HTML/AI-Schema) per client type (browser, crawler, AI agent, social bot)
• crates/appfront-macros — #[appfront::component] compile-time helper macro
• crates/appfront-cli — the appfront CLI (init/dev/build)

Examples (examples/counter-dom, examples/counter-canvas) live outside the workspace — each has its own Cargo.toml so it can resolve wasm-bindgen/trunk dependencies independently. Not present in a fresh checkout yet; scaffold one locally with appfront init (see docs/quickstart.md).
