The branch's iteration arc went through several headless-demo
implementations (CSS Modules, AI Elements, prompt-kit, shadcn) and a
streaming-markdown experiment with `streamdown`. After the spec
narrowed to shadcn-only and `react-markdown` for assistant rendering,
those component libraries and their satellite packages were left
installed but unused.
Removed (zero importers across `src/`):
- @copilotkit/react-ui (v1 UI; the showcase consumes /v2 hooks only)
- @rive-app/react-webgl2 (animations, never wired)
- @streamdown/cjk, /code, /math, /mermaid + streamdown (replaced by
react-markdown for assistant content)
- @xyflow/react (graph viz, never wired)
- ai (Vercel AI SDK, was the AI Elements demo's transport)
- ansi-to-react (terminal output, never wired)
- marked (alternative markdown parser, never wired)
- media-chrome (media player UI, never wired)
- motion (animation library, was a prompt-kit demo dep)
- nanoid (we use crypto.randomUUID())
- react-jsx-parser (never wired)
- remark-breaks (markdown extension, never wired)
- shiki (syntax highlighting, never wired)
- tokenlens (never wired)
- use-stick-to-bottom (was an AI Elements dep)
- @radix-ui/react-use-controllable-state (no importers)
Kept everything actually imported: shadcn primitive surface intact
(class-variance-authority, cmdk, embla-carousel-react, lucide-react,
radix-ui umbrella + per-package @radix-ui/react-checkbox /
react-separator for beautiful-chat's local components), CopilotKit v2,
Hashbrown + json-render BYOC catalogs, recharts, react-markdown +
remark-gfm, openai (voice route), yaml (manifest parsing), zod.
Build still green at 54 routes. Lockfile updated. tsconfig.json
`jsx: "preserve"` — Next 15 reset this from `react-jsx` automatically
on build.
Foundational layer that the per-demo work in subsequent commits builds on.
- Manifest-driven landing page (src/app/page.tsx) — auto-generated grid
of demo cards from manifest.yaml, grouped by tag with explicit ordering
for chat-ui / interactivity / generative-ui / agent-state / multi-agent
/ headless / platform.
- Per-demo titles (src/middleware.ts + src/app/demos/layout.tsx).
- Diagnostic console gated to NODE_ENV=production in app/layout.tsx so
deployed showcases surface uncaught errors and iframe context.
- src/app/globals.css — Tailwind v4 @theme inline block that maps
showcase CSS variables into Tailwind theme tokens (without it, shadcn
utilities like bg-muted / text-foreground compile to nothing). body
intentionally NOT given width:100% so <CopilotSidebar /> can shrink
the document via marginInlineEnd.
- shadcn primitives under src/components/ui/ + src/lib/utils.ts.
- tsconfig.json — @/* path alias rooted at src/.
Removed:
- src/app/copilotkit-overrides.css (global override layer, superseded
by per-demo theming)
- src/app/api/copilotkit-mcp-apps/route.ts (replaced with
[[...slug]]/route.ts so v2 subpath POSTs like /v2/agent/run resolve)
The showcase framework directories better reflect their role as
integration examples rather than distributable packages.
Renames showcase/packages/ -> showcase/integrations/ and updates
the test docker-compose file reference accordingly.
