Middleware

Composable HTTP middleware following Go's standard net/http pattern. All middleware follow the signature:

type Middleware func(h http.Handler) http.Handler

Available middleware:

• Logging - Request logging with structured logging (log/slog)
• MaxBytesReader - Request body size limiting
• SetContentType - Response Content-Type header setting

Example:

package main

import (
    "log/slog"
    "net/http"
    "os"

    "github.com/harrydayexe/GoWebUtilities/middleware"
)

func main() {
    logger := slog.New(slog.NewJSONHandler(os.Stdout, nil))

    handler := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte(`{"status":"ok"}`))
    })

    stack := middleware.CreateStack(
        middleware.NewLoggingMiddleware(logger),
        middleware.NewMaxBytesReader(1024*1024), // 1MB limit
        middleware.NewSetContentTypeJSON(),
    )

    http.ListenAndServe(":8080", stack(handler))
}
