# Frontend (React + TypeScript) — placeholder
|
||
|
|
|
||
|
|
Phase 0 task **"React + TypeScript frontend scaffolding"** (Dev 2) and all later
|
||
|
|
viewer/editor UI lives here. Not implemented yet — this session scaffolds the
|
||
|
|
C++ build pipeline only.
|
||
|
|
|
||
|
|
Planned responsibilities (see the engine blueprint §9):
|
||
|
|
|
||
|
|
- Layered viewer: canvas layer, selection layer, annotation layer, overlay layer.
|
||
|
|
- PDF <-> canvas <-> zoomed coordinate mapping.
|
||
|
|
- Virtualized page rendering (only visible pages).
|
||
|
|
- Talks to the gateway over HTTP; later, to the engine directly via WASM.
|
||
|
|
|
||
|
|
Setup when implemented: Vite + React + **TypeScript strict mode** from day one.
|
||
|
|
|
||
|
|
```

|
frontend/
|
||
|
|
package.json
|
||
|
|
tsconfig.json # "strict": true
