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).
Built-in Agent (TanStack AI) Showcase
CopilotKit's BuiltInAgent in factory mode with TanStack AI as the LLM backend.
The agent runs in-process inside the Next.js API route — there is no separate agent server process to start (unlike the LangGraph TypeScript variant which spawns langgraph-cli on port 8123).
Quick Start
Prerequisites
- Node.js 18+

- Start the dev server
npm run dev
Open http://localhost:3000 to see the demo index.
Build
npm run build
