Adds @databricks/appkit-vector-search — a plugin that gives Databricks Apps built with AppKit instant vector search query capabilities. Ships backend (Express routes, VS REST API client, auth) and frontend (React hook, styled components with Radix UI). Developer experience target: ~45 lines for a full search page with search box, results, filters, and keyword highlighting. 82 tests included. Validated against real VS index on dogfood.
- Move from packages/vector-search/ into packages/appkit/src/plugins/vector-search/ - Replace custom auth (ServicePrincipalTokenProvider, OboTokenExtractor) with AppKit's built-in asUser(req) and getWorkspaceClient() context - Add VectorSearchConnector using workspaceClient.apiClient.request() instead of raw fetch with manual token management - Plugin now extends Plugin base class with proper manifest.json, defaults.ts, this.route(), this.execute(), and toPlugin() factory - Remove standalone package.json, tsconfig.json, and vitest config - Register plugin and connector in index barrel exports Addresses review feedback: - Plugin lives under plugins/ folder alongside analytics, genie, files - No custom auth handling — uses AppKit's built-in mechanisms - Follows create-core-plugin patterns (manifest, defaults, connector) Signed-off-by: Adam Gurary <adam.gurary@databricks.com>
- Connector: wrap VS API calls in telemetry spans with index name, query type, result count, and latency attributes - Connector: check AbortSignal before executing requests - Connector: add WideEvent context logging with query metadata - Plugin: replace this.execute() in route handlers with direct try/catch — preserves actual error details (code, message, status) instead of swallowing them into undefined - Remove unused SearchFilters import Signed-off-by: Adam Gurary <adam.gurary@databricks.com>
