Cache

Cache middleware for Fiber designed to intercept responses and cache them. This middleware will cache the Body, Content-Type and StatusCode using the c.Path() as unique identifier. Special thanks to @codemicro for creating this middleware for Fiber core!

Examples

Import the middleware package that is part of the Fiber web framework

import (
	"github.com/gofiber/fiber/v2"
	"github.com/gofiber/fiber/v2/middleware/cache"
)

After you initiate your Fiber app, you can use the following possibilities:

// Initialize default config
app.Use(cache.New())

// Or extend your config for customization
app.Use(cache.New(cacge.Config{
	Next: func(c *fiber.Ctx) bool {
		return c.Query("refresh") == "true"
	}
	Expiration: 30 * time.Minute,
}))

Config

// Config defines the config for middleware.
type Config struct {
	// Next defines a function to skip this middleware when returned true.
	//
	// Optional. Default: nil
	Next func(c *fiber.Ctx) bool

	// Expiration is the time that an cached response will live
	//
	// Optional. Default: 5 * time.Minute
	Expiration time.Duration
}

Default Config

// ConfigDefault is the default config
var ConfigDefault = Config{
	Next:       nil,
	Expiration: 5 * time.Minute,
}
