May 2026 monthly summary for SigNoz/signoz focusing on API contract stability, RBAC scalability, and frontend developer experience. Key features delivered and business value: - Auth Domain API enhancements and contract simplification: Added GET /api/v1/domains/{id} with correct scoping to the caller's organization, nested AuthDomain config under a named Config field, fixed the UpdateableAuthDomain rename to UpdatableAuthDomain, and returned only the new ID on CreateAuthDomain (Identifiable). Frontend updated to reflect the new shape; OpenAPI/specs and the Orval client regenerated to ensure end-to-end consistency. - Authorization model overhaul and role/permissions management: Moved authtypes into coretypes, introduced new coretypes-based resources and relations for roles/permissions, and added a ListResources accessor. This establishes a scalable, type-safe RBAC foundation and reduces cross-package coupling for future permissions features. Frontend permissions types regenerated to reflect the new coretypes surface. - OpenAPI/frontend alignment and client readiness: Regenerated OpenAPI specs and frontend API clients to fix dangling refs (#/components/schemas), align oneOf/discriminator usage, and ensure the frontend stays in sync with backend contract changes. Major bugs fixed: - API shape mismatches corrected: nested config in responses, Updateable renamed to Updatable, and CreateAuthDomain now returns Identifiable with 201 Created semantics; frontend mocks and tests updated accordingly. - Frontend/client stability: fixed OpenAPI refs and TypeScript typings to prevent runtime client errors after contract changes. - Scheduling/config parsing: addressed string driver values handling in Schedule.Scan and Recurrence.Scan to prevent zero-valued GET results due to driver type mismatches. Overall impact and accomplishments: - Strengthened security posture and API consistency across backend and frontend; reduced future maintenance by centralizing type and resource modeling; improved developer experience with reliable codegen and stable clients. Technologies/skills demonstrated: - Go backend enhancements, OpenAPI/JSONSchema discipline, TypeScript/Orval-based client generation, coretypes/authtypes refactor, and RBAC design evolution.

April 2026 monthly summary: Strengthened observability, API resilience, and testing infrastructure across SigNoz. Delivered end-to-end auditing/telemetry capabilities, deployment-friendly routing changes, API modernization, and tooling updates that improved security, deploy flexibility, and developer velocity. Key features delivered: - Auditing and Telemetry Infrastructure: Establish auditing middleware, handler-level AuditDef, response capture, and resource filtering improvements with auditor integration. This unifies observability and audit logging, enabling structured auditing with consistent provenance across requests. - Reverse Proxy Route Prefix Support: Derive HTTP route prefixes from global.external_url and inject a dynamic base href for sub-path deployments behind reverse proxies. Health endpoints remain accessible without the prefix, simplifying deployments behind API gateways or static hosts. - Ruler and Downtime API Modernization: Modernized the API surface with v2 read types, new interfaces, stricter validations, and improved error handling. Added 201 Created semantics for creates, structured error typing, and OpenAPI schema refinements; improved maintainability via cleaner abstractions and move to v2 routes. - Frontend API Client Refactor: Migrated frontend code to generated API clients for rules and downtime, reducing drift, improving type safety, and enabling faster iteration with the API surface. - Testing and Tooling Modernization: Consolidated testing into a shared pytest project, added Playwright-based e2e telemetry seeding, upgraded dependencies, and introduced unified fixtures. This increased test reliability, coverage, and CI stability. - MCP URL Visibility Option: Added optional mcp_url to global config and surfaced it in frontend types; enables gating of MCP settings page and improves UX consistency across environments. Overall impact and accomplishments: - Improved security and traceability through a unified auditing model and structured audit events. - Deployment flexibility gained by supporting reverse-proxy sub-paths without code changes. - API resilience and developer velocity improved via v2 API modernization and generated frontend clients. - Increased confidence in releases through unified testing, tooling modernization, and upgraded dependencies. - Clearer configuration and UX around MCP visibility and global config fields. Technologies/skills demonstrated: - Go: auditing middleware, middleware consolidation, and auditing event factories (AuditDef, AuditEvent, etc.). - OpenTelemetry/Observability: structured auditing, resource filtering, and logging integration. - API architecture: v2 surface, OpenAPI schema tightening, error typing, 201 Created semantics. - Frontend/TypeScript: generated API clients, type-safe integration with backend APIs. - Testing/CI: unified pytest project, Playwright/e2e telemetry seeding, dependency upgrades, and test infrastructure modernization. - Deployment: reverse proxy integration, dynamic base href handling, and global config expansions (mcp_url). - Documentation and standards: core-type conventions, API docs, and governance updates. Notes: - Several commits across features, tests, and tooling were aggressively focused on stability, security, and maintainability, with broad changes spanning backend, frontend, and testing ecosystems.
