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)
20 primary per-package Playwright specs plus 3 testing-kind stubs
(~75 test blocks). Selectors discipline: testids, role-based,
verbatim text; never LLM-text assertions. Enter-key submit replaced
with copilot-send-button testid (Enter flakes on Railway slow paths).
All non-skipped tests green 3x against Railway.
Lockfile was stale after rebase — hashbrown deps not in pnpm-lock.yaml.
Also applies oxfmt formatting and syncs next.config.ts webpack alias
with the simplified form from main.
Each package's 3 GenUI demo pages now include the RendererSelector pill toggle,
allowing users to switch between 4 active rendering strategies (json-render
falls back to tool-based until the Zod 4 isolated bundle is built).
Each package wraps shared tools in its framework's idiom, demo pages import
from @copilotkit/showcase-shared via tsconfig paths. Comprehensive Playwright
e2e tests adapted per package (130+ test files).
Cross-cutting fixes: debug routes (/ok→/health), dead code removal,
error boundaries, thread safety, langroid adapter, claude-sdk-ts text emission.
