This is the gofiber/fiber v3 repository, a high-performance, Express-inspired web framework written in Go. The framework provides a full-featured HTTP server with routing, middleware composition, request binding, session management, caching, logging, and an integrated HTTP client. It is built on top of the valyala/fasthttp library, emphasizing speed and low memory allocation. The architecture is library-based: users create an App instance, define routes and middleware, and start the server. The codebase is well-structured with extensive internal packages for common concerns (e.g., URL normalization, header parsing, template formatting). It includes over 30 built-in middleware packages, many of which are configurable and support pluggable storage backends. The code demonstrates strong engineering practices: extensive test coverage (including fuzz tests), object pooling, SIMD-style optimizations, and security-conscious design (SSRF protection, CSRF, redirect validation). Despite some internal complexity and duplication, it is a mature, actively maintained framework suitable for production use.

This is a monorepo of first-party middleware and service implementations for the Fiber web framework (v3). It provides production-grade authentication (JWT, PASETO, SPNEGO/Kerberos), authorization (Casbin, OPA), observability (OpenTelemetry, Prometheus, New Relic, Sentry, custom monitor/uptime dashboards), real-time communication (WebSocket, Socket.IO v5), Web Application Firewall (Coraza), resilience patterns (circuit breaker, CPU load shedding), structured logging (zap, zerolog), internationalization, hCaptcha verification, Swagger UI/OpenAPI docs, profiling (fgprof), and Testcontainers integration for testing. Each package lives in its own Go module under v3/, following a consistent Config+New() pattern and includes extensive test coverage with benchmarks. The architecture is library-oriented: components are imported by Fiber applications, not run standalone. The codebase demonstrates strong engineering practices: config validation at construction, atomic concurrency patterns, lock-free read paths, and protocol-level optimizations (e.g., zero-copy Socket.IO codec, WebSocket write coalescing). Some packages show signs of technical drift (e.g., paseto uses a deprecated library, socketio has mutable package globals), but overall the repository is actively maintained with weekly releases and automated dependency updates.
