Example of auth middleware for fasthttp & fasthttprouter

type Middleware func(h fasthttp.RequestHandler) fasthttp.RequestHandler
type AuthFunc func(ctx *fasthttp.RequestCtx) bool
func NewAuthMiddleware(authFunc AuthFunc) Middleware {
    return func(h fasthttp.RequestHandler) fasthttp.RequestHandler {
        return func(ctx *fasthttp.RequestCtx) {
            result, err := authFunc(ctx)
            if result {
                h(ctx)
            } else {
                ctx.Response.SetStatusCode(fasthttp.StatusUnauthorized)
            }
        }
    }
}

func AuthCheck(ctx *fasthttp.RequestCtx) (bool, error) {
    return false; // for example ;)
}

// router
authMiddleware := middleware.NewAuthMiddleware(security.AuthCheck)
...
router.GET("/protected", authMiddleware(handlers.ProtectedHandler))

i think middleware should not too coupled in the router. you should implement your middleware in your appliaction yourself because it depends on how the security of your appliaction.
