Aligns dependency versions across all 19 showcase integrations to current
released minor versions for the 1.60.2 release cycle.
Package families:
- @copilotkit/{a2ui-renderer, react-core, react-ui, runtime, shared, sdk-js, voice}
1.59.4 -> 1.60.2 (18 integrations already staged; ms-agent-harness-dotnet
catches up from 1.57.2)
- @ag-ui/{client, core, encoder} 0.0.55 -> 0.0.57
- @ag-ui/mastra 0.2.1-beta.2 -> 0.2.4 (stable on 0.x; 1.0.x major held back)
Includes the previously-missed ms-agent-harness-dotnet integration in the
@copilotkit/* bump, plus the @copilotkit/web-inspector override pin.
Lockfile-only reconciliation via npm install --package-lock-only
--legacy-peer-deps (cmdk@0.2.1 pre-existing react^18 peer-dep is unaffected).
Add a dedicated Spring/Java ReasoningController (/reasoning/) that
reimplements the ag2 reasoning_agent.py BEHAVIOR: it makes a direct
streaming chat-completions call, reads the native delta.reasoning_content
channel (with a <reasoning>...</reasoning> regex fallback), and emits
RUN_STARTED -> REASONING_MESSAGE_START/CONTENT/END -> TEXT_MESSAGE_*
-> RUN_FINISHED so the CopilotKit reasoning slot mounts
[data-testid="reasoning-block"].
Spring AI's ChatClient drops delta.reasoning_content and the AG-UI Java
SDK has no REASONING_MESSAGE_* event types (only THINKING_*, which
@ag-ui/client drops), so the controller manages its own SseEmitter and
writes the reasoning frames as raw JSON matching the @ag-ui/client 0.0.55
wire schema. Header forwarding (x-aimock-context) rides the existing
WebClientConfig exchange filter. Wire route reasoning-custom/-default (plus
legacy aliases) to /reasoning/, mirroring ag2's reasoningAgentNames, and
bump @ag-ui/client ^0.0.43 -> 0.0.55 for REASONING_MESSAGE_* decode support.
(cherry picked from commit 4d183371c489013f0a7bcce1a447078164974aef)
Bump canonicalCopilotKitVersion 1.59.2 -> 1.59.4 and pin every
integration's @copilotkit/* to 1.59.4 (locks regenerated). Keeps the
whole showcase on one version instead of letting the langgraph A2UI
demos deviate. Existing per-slug overrides (built-in-agent pkg.pr.new,
ms-agent-harness-dotnet 1.57.2) unchanged.
The "next" dist-tag was a workaround for Docker builds that can't resolve
workspace:* — but "next" has gone stale (1.55.2-next.1) while "latest" is
at 1.56.5. Renovate doesn't cover showcase/, so these never auto-bumped.
Switch all 19 showcase package.json files to "latest".
Add interrupt demos (Strategy B), byoc-json-render demo (zero-tool
agent + @json-render frontend), and shared-state-streaming (per-token
STATE_SNAPSHOT emission via tool-call argument interception).
Spring AI moves from 4 unsupported features to 0.
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.
