# Langroid showcase — parity notes
|
|
|
|
Tracks demos from the canonical `showcase/integrations/langgraph-python/manifest.yaml`
|
|
that are either deliberately skipped or deferred for the Langroid integration.
|
|
|
|
Canonical list: 36 demos (excluding `cli-start`).
|
|
|
|
## Ported
|
|
|
|
### Wave 1 (initial scaffold)
|
|
|
|
- agentic-chat
|
|
- hitl-in-chat (route: `/demos/hitl`)
|
|
- tool-rendering
|
|
- gen-ui-tool-based
|
|
- gen-ui-agent
|
|
- shared-state-read-write
|
|
- shared-state-streaming
|
|
- subagents
|
|
|
|
### Wave 2 (chat chrome + reasoning)
|
|
|
|
- chat-customization-css
|
|
- prebuilt-sidebar
|
|
- prebuilt-popup
|
|
- chat-slots
|
|
- headless-simple
|
|
- frontend-tools
|
|
- frontend-tools-async
|
|
- hitl-in-app
|
|
- agentic-chat-reasoning
|
|
- reasoning-default-render
|
|
- readonly-state-agent-context
|
|
|
|
### Wave 3 (batch B4 second pass)
|
|
|
|
- tool-rendering-default-catchall
|
|
- tool-rendering-custom-catchall
|
|
- declarative-gen-ui (A2UI dynamic schema — reuses agent's `generate_a2ui` tool)
|
|
- auth (dedicated `/api/copilotkit-auth` route with `onRequest` hook)
|
|
- headless-complete (frontend-only, reuses unified runtime)
|
|
- agent-config (frontend + dedicated route + backend wired end-to-end;
|
|
`forwardedProps.config.configurable.properties` steers the agent's
|
|
system prompt per run)
|
|
|
|
### Wave 4 (showcase-fill-186)
|
|
|
|
- cli-start (informational manifest entry — `npx copilotkit@latest init
|
|
--framework langroid`)
|
|
- gen-ui-tool-based (manifest entry only — frontend already shipped in
|
|
Wave 1; the agent's `generate_haiku` frontend tool was the missing
|
|
manifest link)
|
|
- hitl-in-chat (frontend-only — `useHumanInTheLoop` with a `book_call`
|
|
tool defined client-side; the Langroid agent calls it via the same
|
|
AG-UI runtime path as any other tool)
|
|
- hitl-in-chat-booking (alias of hitl-in-chat, identical route — mirrors
|
|
the langgraph-python manifest where both demos point at the same
|
|
page)
|
|
|
|
## Skipped — Langroid lacks the framework primitive
|
|
|
|
- **gen-ui-interrupt** — uses `useLangGraphInterrupt` + LangGraph's
|
|
`interrupt()` node + `Command(resume=...)` lifecycle. Langroid has no
|
|
equivalent interrupt primitive and the current AG-UI adapter emits no
|
|
interrupt events.
|
|
- **interrupt-headless** — same reason as `gen-ui-interrupt`.
|
|
- **mcp-apps** — the LangGraph showcase relies on the runtime
|
|
`mcpApps: { servers: [...] }` middleware to inject MCP-server-backed
|
|
tools into the agent at request time. Langroid's custom AG-UI adapter
|
|
goes directly to the OpenAI Chat Completions API with a static tool
|
|
list built from `ALL_TOOLS`, so the runtime-level tool injection
|
|
never reaches the LLM. Porting requires a Langroid-aware AG-UI
|
|
adapter that consumes the runtime-injected tool descriptors per turn.
|
|
|
|
## Deferred — portable in principle, requires additional agent or runtime work
|
|
|
|
Each of these is achievable but needs a dedicated Langroid agent tool / module
|
|
that we did not take on in this pass. They are tracked so a follow-up can
|
|
pick them up without re-litigating scope.
|
|
|
|
- **tool-rendering-reasoning-chain** — needs the Langroid AG-UI adapter to
|
|
emit reasoning events; the current adapter only emits text + tool deltas.
|
|
- **a2ui-fixed-schema** — needs a dedicated agent that loads JSON schemas
|
|
at startup and exposes a `display_flight`-shaped tool backed by the same
|
|
A2UI middleware path.
|
|
- **byoc-json-render** — needs a Langroid agent that streams structured
|
|
JSON matching the `@json-render/react` Zod catalog, plus a dedicated BYOC
|
|
runtime route.
|
|
- **byoc-hashbrown** — needs a Langroid agent that streams structured
|
|
output matching the hashbrown schema, plus a dedicated BYOC runtime route.
|
|
- **beautiful-chat** — polished starter chat. Large frontend (example-layout,
|
|
example-canvas, generative-ui charts, hooks). Requires combining
|
|
openGenerativeUI + a2ui on one dedicated runtime route.
|
|
- **multimodal** — needs a Langroid agent configured with a vision-capable
|
|
LLM and a dedicated runtime that accepts CopilotChat attachments
|
|
(images + PDFs).
|
|
- **voice** — needs the `@copilotkit/voice` plumbing plus a dedicated voice
|
|
runtime route and sample audio assets.
|
|
- **open-gen-ui** — needs a Langroid agent that emits a `generateSandboxedUi`
|
|
tool call; the runtime `openGenerativeUI` middleware converts that stream
|
|
into activity events.
|
|
- **open-gen-ui-advanced** — same agent surface as `open-gen-ui` plus
|
|
host-side `sandboxFunctions` wiring on the frontend.
|
|
- **mcp-apps** — Langroid does ship an MCP client surface, but the canonical
|
|
demo is tightly coupled to the LangGraph activity-message emission path.
|
|
A Langroid port needs a custom AG-UI adapter path that emits the
|
|
MCP-apps activity events.
|
|
|
|
## Known limitations
|
|
|
|
(none currently tracked — previous agent-config backend gap was closed by
|
|
propagating upstream PR #4271's forwardedProps repack + backend system-
|
|
prompt wiring.)
