Middlewares

httpx.Chain composes middlewares around a handler. It takes any number of httpx.Middleware and applies them in reverse order before executing the wrapped handler.

httpx.Middleware accepts both function types:

• func(http.Handler) http.Handler
• func(http.HandlerFunc) http.HandlerFunc

func (h *NoteHandler) CreateNote() http.HandlerFunc {
		return httpx.Chain(
			mw.ProvideUserContext
		)(func(r *http.Request) (httpx.Response, error) {
				// business logic
				return httpx.JSON.Created(nil), nil
		})
}

It is also convenient to have this located with your handler for testing because you are not forced to spin up the whole router to test a single handler.

You can add global middlewares in internal/provide/provide_http.go like the logger one.

See the middlewares section for more details on available middlewares.
