Features

CORS Filter: Configurable Cross-Origin Resource Sharing middleware
Support for allowed origins, methods, headers, and credentials
Easy integration with the Turbo router

Usage

CORS Filter

import (
    "oss.nandlabs.io/golly/turbo"
    "oss.nandlabs.io/golly/turbo/filters"
)

// Create a CORS filter with allowed origins
cors := filters.NewCorsFilter("https://example.com", "https://app.example.com")

// Or configure CORS options in detail
opts := &filters.CorsOptions{
    AllowedOrigins: []string{"*"},
    AllowedMethods: []string{"GET", "POST", "PUT", "DELETE"},
    AllowedHeaders: []string{"Content-Type", "Authorization"},
}

// Attach to a Turbo router
router := turbo.NewRouter()
router.AddCorsFilter(opts)

Custom Filters

You can create custom filters (middleware) that wrap the http.Handler chain:

func rateLimitFilter(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        // Check rate limit...
        next.ServeHTTP(w, r)
    })
}

route, _ := router.Get("/api/data", dataHandler)
route.AddFilter(rateLimitFilter)
