Functions

func CORS 

func CORS() echo.MiddlewareFunc

CORS returns a CORS middleware configured for the application. It allows cross-origin requests with appropriate security headers.

func DELETE added in v0.3.0 

func DELETE[T any, R any](hr *HandlerRegistry, r RouteRegistrar, path string, handler HandlerFunc[T, R], opts ...RouteOption)

DELETE registers a DELETE handler with optional route configuration.

func EscalateSeverity added in v0.13.0 

func EscalateSeverity(c echo.Context, level zerolog.Level)

EscalateSeverity allows application code to explicitly escalate request severity. Useful for non-logging events that should trigger WARN+ action logs (e.g., rate limiting).

Example: 

if rateLimit.Exceeded() {
    server.EscalateSeverity(c, zerolog.WarnLevel)
}

Thread-safe: Can be called from multiple goroutines concurrently.

func GET added in v0.3.0 

func GET[T any, R any](hr *HandlerRegistry, r RouteRegistrar, path string, handler HandlerFunc[T, R], opts ...RouteOption)

GET registers a GET handler with optional route configuration. 

func HEAD[T any, R any](hr *HandlerRegistry, r RouteRegistrar, path string, handler HandlerFunc[T, R], opts ...RouteOption)

HEAD registers a HEAD handler with optional route configuration.

func IPPreGuard added in v0.9.0 

func IPPreGuard(threshold int) echo.MiddlewareFunc

IPPreGuard returns an IP-based rate limiting middleware for early attack prevention. This middleware runs before tenant resolution to block obvious attacks and invalid tenant sprays. It uses a higher threshold than the main rate limiter and only protects against IP-based attacks. If threshold is 0 or negative, IP pre-guard is disabled.

func LoggerWithConfig added in v0.13.0 

func LoggerWithConfig(log logger.Logger, cfg LoggerConfig) echo.MiddlewareFunc

LoggerWithConfig returns a request logging middleware with custom configuration. It implements dual-mode logging:

  • Action logs (log.type="action"): Request summaries for INFO-level requests
  • Trace logs (log.type="trace"): Application debug logs (WARN+ only)

The middleware tracks request-scoped severity escalation. If any log during the request lifecycle reaches WARN+, the request is logged as a trace log. Otherwise, a synthesized action log summary is emitted at request completion.

func OPTIONS added in v0.5.0 

func OPTIONS[T any, R any](hr *HandlerRegistry, r RouteRegistrar, path string, handler HandlerFunc[T, R], opts ...RouteOption)

OPTIONS registers an OPTIONS handler with optional route configuration.

func PATCH added in v0.3.0 

func PATCH[T any, R any](hr *HandlerRegistry, r RouteRegistrar, path string, handler HandlerFunc[T, R], opts ...RouteOption)

PATCH registers a PATCH handler with optional route configuration.

func POST added in v0.3.0 

func POST[T any, R any](hr *HandlerRegistry, r RouteRegistrar, path string, handler HandlerFunc[T, R], opts ...RouteOption)

POST registers a POST handler with optional route configuration.

func PUT added in v0.3.0 

func PUT[T any, R any](hr *HandlerRegistry, r RouteRegistrar, path string, handler HandlerFunc[T, R], opts ...RouteOption)

PUT registers a PUT handler with optional route configuration.

func PerformanceStats 

func PerformanceStats() echo.MiddlewareFunc

PerformanceStats returns middleware that initializes operation tracking for each request. It adds both AMQP message counter and database operation counter to the request context that can be incremented by messaging clients and database layer, then logged in the request logger.

func RateLimit 

func RateLimit(requestsPerSecond int) echo.MiddlewareFunc

RateLimit returns a rate limiting middleware with the specified requests per second. It limits the number of requests from each IP address to prevent abuse. If requestsPerSecond is 0 or negative, rate limiting is disabled.

func RegisterHandler added in v0.3.0 

func RegisterHandler[T any, R any](
	hr *HandlerRegistry,
	r RouteRegistrar,
	method, path string,
	handler HandlerFunc[T, R],
	opts ...RouteOption,
)

RegisterHandler registers a typed handler with the route registrar and captures metadata.

func SetupMiddlewares 

func SetupMiddlewares(e *echo.Echo, log logger.Logger, cfg *config.Config, healthPath, readyPath string)

SetupMiddlewares configures and registers all HTTP middlewares for the Echo server. It sets up CORS, logging, recovery, security headers, rate limiting, and other essential middleware. healthPath and readyPath are used by the tenant middleware skipper to bypass probe endpoints.

func TenantMiddleware added in v0.9.0 

func TenantMiddleware(resolver multitenant.TenantResolver, skipper SkipperFunc) echo.MiddlewareFunc

TenantMiddleware resolves the tenant ID and injects it into the request context. If a skipper function is provided, certain routes (e.g., health probes) can bypass tenant resolution. If skipper is nil, all routes will undergo tenant resolution.

func Timeout added in v0.13.0 

func Timeout(duration time.Duration) echo.MiddlewareFunc

Timeout returns middleware that adds a request-scoped deadline without swapping Echo's response writer. When the configured duration elapses the handler will observe context cancellation and higher layers will surface a 503 via the centralized error handler.

Why not use Echo's middleware.TimeoutWithConfig? Echo's timeout wraps net/http.TimeoutHandler which swaps the response writer with a timeoutWriter. When timeouts occur, this invalidates Echo's response object (c.Response() returns nil), causing panics in logging/middleware that access response headers/status. By using context-only timeouts, we maintain response validity while still enforcing deadlines.

func Timing 

func Timing() echo.MiddlewareFunc

Timing returns a middleware that adds response time headers to HTTP responses. It measures request processing time and adds an X-Response-Time header.

func TraceContext added in v0.3.0 

func TraceContext() echo.MiddlewareFunc

TraceContext injects the resolved trace ID and W3C trace context headers from the Echo request/response into the request context, so that outbound HTTP clients can propagate them without depending on Echo.

func WrapHandler added in v0.3.0 

func WrapHandler[T any, R any](
	handlerFunc HandlerFunc[T, R],
	binder *RequestBinder,
	cfg *config.Config,
) echo.HandlerFunc

WrapHandler wraps a business logic handler into an Echo-compatible handler. It handles request binding, validation, response formatting, and error handling. Supports both value and pointer types for requests (T) and responses (R). Pointer types eliminate copy overhead for large payloads (>1KB recommended).

This function now delegates to handlerWrapper which composes specialized components: - contextChecker: Detects request cancellation/timeout - requestProcessor: Allocates, binds, and validates requests - responseHandler: Formats success and error responses
