Starting the /demos/auth cell unauthenticated meant the initial `/info`
handshake from CopilotKit returned 401 before any React error handler
could attach, crashing the page on load. Flip the default so the demo
mounts already signed in — the chat is immediately usable — and expose
Sign out / Sign in as the toggle for exercising the 401 path.
- use-demo-auth: default state flipped from unauthed to authed so the
page mounts with a valid Bearer header.
- page.tsx: add a ChatErrorBoundary around <CopilotChat /> that catches
any render-time throw from chat internals after signing out and shows
a friendly in-page message instead of white-screening. The boundary
resets on auth transitions so signing back in restores a live chat.
- auth-banner: rename Authenticate -> Sign in; status copy updated to
Signed in / Signed out to match the inverted default.
- tests/e2e/auth.spec.ts: flip assertions — page loads authenticated,
sign out triggers 401 on next send with banner still mounted, and
sign in clears the error and restores successful sends.
- qa/auth.md: refreshed checklist for the authenticated-default flow.
Resolves conflicts:
- manifest.yaml / constraints.yaml / docs-links.json: keep both byoc-json-render
and main's re-wired open-gen-ui + open-gen-ui-advanced entries
- scripts/hooks/check-binaries.sh: keep both shell-docs and shell-dojo
demo-content exclusions (identical lines, different ordering)
- pnpm-lock.yaml (langgraph-python): regenerated via pnpm install
- shell/shell-dojo/shell-docs data JSONs: accept main's deletion (now
regenerated by nx targets), then regenerate via scripts/generate-registry.ts
and scripts/bundle-demo-content.ts
Bump generate-registry.test expected feature/demo count 32 -> 33 to account
for the new byoc-json-render demo.
Resolves textual conflicts in manifest.yaml and docs-links.json (keeps
both open-gen-ui* from main and agent-config from this branch). Accepts
main's deletion of generated shell*/src/data/*.json (now gitignored).
Bumps langgraph-python feature/demo count test from 32 to 33.
Resolved conflicts:
- showcase/packages/langgraph-python/manifest.yaml: kept auth (HEAD) +
open-gen-ui / open-gen-ui-advanced (main) in both features and demos.
- showcase/packages/langgraph-python/docs-links.json: kept auth entry
from HEAD alongside updated subagents shell_docs_path.
- showcase/shared/constraints.yaml: kept auth + open-gen-ui* entries.
- Deleted shell/shell-dojo/shell-docs generated JSONs per main (now
generated at build, no longer committed).
Bumped langgraph-python feature/demo count 32 -> 33 in generate-registry
test to reflect the added auth demo.
Wave 4a. Port the starter's hashbrown renderer into a dedicated
single-mode langgraph-python demo at /demos/byoc-hashbrown so the
byoc-hashbrown row goes green on the dashboard.
- @hashbrownai/core + @hashbrownai/react + recharts deps added.
- Dedicated /api/copilotkit-byoc-hashbrown route with byoc_hashbrown
graph (ChatOpenAI + CopilotKitMiddleware) and a catalog-aware
system prompt coaching the LLM to emit a <ui>...</ui> envelope.
- Ported MetricCard + bar-chart + pie-chart + chart-config from
showcase/starters/template/frontend with data-testid hooks on
chart roots for E2E coverage.
- Ported hashbrown renderer with local RenderMessageProps /
AssistantMessage types so @copilotkit/react-ui and @ag-ui/core
do not become direct deps of this package.
- Updated hashbrown schema calls to @0.5.0-beta.4 surface:
enumeration for SalesStage; description-first streaming.array +
object; dropped the non-existent .optional() chain.
- v2 CopilotChat uses messageView.assistantMessage slot and
useConfigureSuggestions for 3 canned prompts (sales dashboard /
revenue by category / expense trend).
- QA checklist + Playwright E2E authored (not run pre-deploy).
- Manifest / constraints / docs-links updated and derived registry +
demo-content + docs-status bundles regenerated.
- Extend scripts/hooks/check-binaries.sh whitelist to include the
shell-docs and shell-dojo demo-content bundles so the pre-commit
hook does not reject the regenerated 1.5 MB files it produced.
Wire CopilotChat AttachmentsConfig (image + PDF, inline base64) into a
dedicated /demos/multimodal cell backed by a vision-capable LangGraph
agent (gpt-4o). Scoped to its own runtime route so the vision cost
stays on this demo.
- Dedicated /api/copilotkit-multimodal route registering the new
multimodal graph under the multimodal-demo slug
- src/agents/multimodal_agent.py with an AgentMiddleware that flattens
PDF content parts to text server-side via pypdf
- Try with sample image / PDF buttons that drive CopilotChats own
hidden file input via DataTransfer + change event, so the sample and
paperclip paths exercise the same useAttachments pipeline
- public/demo-files/ placeholder — sample.png / sample.pdf binaries
are produced by the user at the end of the Wave 2b rollout
- Manifest + registry + constraints + docs-links wired; normalized
multi-modal -> multimodal in constraints to match the feature
registry id
- QA checklist + Playwright E2E spec (not run yet — pending deploy)
- aimock fixtures for sample prompts so CI runs are deterministic
- Extend the check-binaries hook allowlist to cover the shell-docs and
shell-dojo demo-content.json mirrors (same size as shell/src/data,
already allowed) so regenerated derived data can be committed
Integrates @json-render/{core,react} as an alternative BYOC generative-UI
rendering technology in langgraph-python, paired with Wave 4a's hashbrown
demo. Both demos share the same sales-dashboard catalog (MetricCard +
BarChart + PieChart) so the dashboard rows are directly comparable.
- Adds @json-render/{core,react} @ 0.18.0 pinned.
- New /demos/byoc-json-render page using CopilotChat's messageView.assistantMessage
slot to bridge CopilotKit output into @json-render/react Renderer.
- New /api/copilotkit-byoc-json-render route + byoc_json_render graph in
langgraph.json.
- Zod-validated catalog reusing @json-render/react/schema's prebuilt spec shape.
- System prompt with 3 worked examples inlined so the agent emits valid
{ root, elements } JSON deterministically.
- QA checklist + Playwright spec authored (E2E run deferred to post-deploy
stabilization).
- Adds shell-docs/shell-dojo demo-content.json to the check-binaries.sh
allowlist (same 1MB-allowed rationale as shell/demo-content.json).
Framework-native request authentication demo for the langgraph-python
showcase. Demonstrates both the unauthenticated (401) failure path and
the authenticated success path via a shared bearer token.
- New /demos/auth page with sticky AuthBanner + in-memory React auth state
- Dedicated /api/copilotkit-auth runtime route using createCopilotRuntimeHandler
from @copilotkit/runtime/v2 with an onRequest hook validating
Authorization: Bearer demo-token-123
- Shared DEMO_TOKEN constant imported by both client and server to prevent drift
- <CopilotKit headers={...}> injects Authorization reactively when authenticated
- Page-level error surface captures 401s via onError and renders a stable
data-testid=auth-demo-error for QA + E2E assertions
- QA checklist + Playwright E2E spec authored (E2E run deferred to post-deploy)
- Manifest, feature list, docs-links, constraints, and derived registry /
demo-content / constraints / docs-status data regenerated
- Allowlist shell-docs / shell-dojo demo-content.json in the binary-size
pre-commit hook (mirrors the Wave 2a voice commit; they are bundled
fixtures already over 1 MB on main)
Wire @copilotkit/voice into a langgraph-python /demos/voice route via a
dedicated runtime (/api/copilotkit-voice) that mounts
TranscriptionServiceOpenAI. The mic button auto-appears in the CopilotChat
composer because the runtime advertises audioFileTranscriptionEnabled=true.
- Per-demo runtime route /api/copilotkit-voice with transcriptionService
- Demo page at /demos/voice with <CopilotChat /> + Play-sample button
- SampleAudioButton fetches /demo-audio/sample.wav and POSTs the
single-route transcribe envelope to the runtime URL, then writes the
transcribed text into the chat textarea via the native setter +
synthetic input event so React state stays in sync
- Manifest, registry, constraints, docs-links wired; shell bundles regenerated
- QA checklist (qa/voice.md) + Playwright E2E spec (tests/e2e/voice.spec.ts)
- public/demo-audio/ placeholder committed; sample.wav to be added by user
- Allowlist shell-docs / shell-dojo demo-content.json in the binary-size
pre-commit hook (they are bundled fixtures, already over 1 MB on main)
22 substantive primary checklists at the qa/agentic-chat.md quality
bar (specific testids, timeouts, expected results) plus 3 short stubs
for testing-kind demos (interrupt-headless, tool-rendering-reasoning-chain,
reasoning-default-render). 25 files total.
Replace TODO placeholders in all 73 QA checklist files across 17 showcase
packages with specific, actionable test steps derived from reading the
actual demo page source code. Each checklist now references real
data-testid selectors, hook names, expected UI states, and interaction
flows.
Add showcase/QA-COVERAGE.md with a comprehensive matrix showing coverage
across manual QA, Vitest unit tests, Playwright E2E (smoke and interaction),
per-package E2E, aimock fixtures, and CI automation for all 9 demos plus
the Sales Dashboard starter hero.
