type Config ¶

type Config struct {
	Host string
	Port string
	URL  string
}

type Handler ¶

type Handler[T any] interface {
	ServeHTTP(http.ResponseWriter, *http.Request, T)
}

Defining custom interface with ServeHTTP signature containing custom parameter to register custom handlers with DB We need to expect not anymore "http.Handler" but simply Handler

type HandlerFunc ¶

type HandlerFunc[T any] func(http.ResponseWriter, *http.Request, T)

Used to type any function that has this signature into a type that implemets the Handler interface, to allow it to be registerd on the mux with a corresponding pattern. Upon pattern match, this function will be invoked it call the user's defined callback function 'f' with all the arguments passed from the multiplexer adapter middleware (the one that turns the standard http.Handler signature with our custom ServeHTTP with db argument)

func (f HandlerFunc[T]) ServeHTTP(w http.ResponseWriter, r *http.Request, c T)

type Router ¶

type Router[T any] struct {
	Mux     *http.ServeMux
	Context T
	// contains filtered or unexported fields
}

func New[T any](context T) *Router[T]

func (router *Router[T]) Handle(pattern string, handler Handler[T])

func (router *Router[T]) HandleFunc(pattern string, handler func(w http.ResponseWriter, r *http.Request, context T))

func (router *Router[T]) Listen(conf *Config) error

func (router *Router[T]) NotFoundHandle(handler Handler[T])

func (router *Router[T]) NotFoundHandleFunc(handler func(http.ResponseWriter, *http.Request, T))

func (router *Router[T]) ServeHTTP(w http.ResponseWriter, r *http.Request)
