## 1. Install
```bash
npx rahman-resources add reel-editor
# alias: npx rr add reel-editor
```
The CLI copies `frontend/slices/reel-editor/` into your project + augments `.env.example` + installs npm deps automatically. Run it from your project root.
## 2. What it ships
- npm: `lucide-react`, `react-resizable-panels`, `sonner`
- shadcn primitives: `button`, `input`, `slider`, `tooltip`, `dialog`, `dropdown-menu`, `resizable`, `sheet`, `sonner`
## 3. Wire it up
Stack: Next 16 + React 19 + Tailwind 4 + shadcn/ui. An in-browser video timeline editor with realtime WebM export. Fully client-side; no backend required.
STEP 1 — Install. `npx rr add reel-editor`. Ensure `@/features/reel-editor` resolves in tsconfig paths and Tailwind scans the slice folder.
STEP 2 — Deps. npm: `lucide-react react-resizable-panels sonner`. shadcn: `npx shadcn@latest add button input slider tooltip dialog dropdown-menu resizable sheet sonner`. Mount `<Toaster />` (sonner) once in your root layout.
STEP 3 — Mount. Render in a height-bearing box:
```tsx
"use client";
import { ReelEditor } from "@/features/reel-editor";
export default function Page() {
return <div className="h-dvh"><ReelEditor /></div>;
}
```
Or register the `reelEditorApp` descriptor in an appshell manifest for windowed hosts.
STEP 4 — Files pane backend (optional). The quick-import pane ships with an in-memory mock. Wire a real filesystem with `configureReelFs({ list, mkdir, rawUrl })` — list/mkdir mirror a simple fs API, rawUrl resolves a listed path to a fetchable media URL.
STEP 5 — Export. The Render button records the live canvas + mixed audio to WebM via MediaRecorder in realtime (duration = composition length). Users can also import local media via the file picker — object URLs, no upload needed.
## Rules of engagement
- shadcn-only UI primitives. No raw `<button>` / `<dialog>` / native date or file inputs.
- 200-line hard cap per source file (extract neighbours when over).
- All Convex queries hit an index (`.withIndex(...)`); never bare `.collect()`.
- Public mutations/queries declare `args:` validators + authz.
