Greptile Overview

Greptile Summary

This PR adds analytics data retrieval capabilities to the Juno platform by implementing 10 new viewer endpoints that expose read-only access to analytics events (click, visit, input, and custom events) through both the gRPC analytics service and REST API gateway.

Key Changes:

• Added AnalyticsViewerService extending bog-analytics SDK's AnalyticsViewer class for read operations
• Implemented 11 new service methods with pagination support and proper authentication/validation
• Created proto definitions for all new RPC endpoints with corresponding auto-generated TypeScript types
• Exposed 10 REST endpoints in API gateway with comprehensive OpenAPI documentation
• Added complete test coverage for both analytics service and API gateway
• All endpoints require API key authentication for security

Minor Issues Found:

• Typo in method name: getCustomGraphTypesbyId should be getCustomGraphTypesById (line 264 in analytics.service.ts)
• TODO comment indicates hardcoded DEVELOPMENT environment needs production configuration

Confidence Score: 4/5

• This PR is safe to merge with one minor typo fix needed
• Score reflects well-structured implementation with comprehensive test coverage and proper validation/authentication patterns. The typo in the method name will cause a runtime error when calling getCustomGraphTypesById, preventing this specific endpoint from working correctly. All other endpoints follow consistent patterns and should work properly. The hardcoded DEVELOPMENT environment is noted but acceptable for initial implementation.
• packages/analytics-service/src/modules/analytics/analytics.service.ts requires a one-character fix to correct the method name typo on line 264

Only returns first type; this should be all types

Analytics tests will be rewritten during sprint day; critical functions tested by hand
