I believe you might need to return here:
if !isHtml(w) {
next.ServeHTTP(w, r)
return
}

Yes it was that, but now I cant get the content type from the header, every time I print it print []map
func isHtml(w http.ResponseWriter) bool {
return strings.HasPrefix(w.Header().Get("Content-Type"), "text/html")
}
type App struct {
Router *chi.Mux
}
func NewApp() *App {
router := chi.NewRouter()
router.Use(middleware.Logger)
return &App{
Router: chi.NewRouter(),
}
}
func (a *App) Middleware(next http.HandlerFunc) http.HandlerFunc {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
if !isHtml(w) {
next.ServeHTTP(w, r)
return
}
w.Write([]byte("<p>Loading...</p>"))
next.ServeHTTP(w, r)
})
}
func (a *App) Component(route string, handler http.HandlerFunc) {
a.Router.Get(route, a.Middleware(handler))
}
func (a *App) Listen(port string) {
http.ListenAndServe(port, a.Router)
}
func main() {
app := NewApp()
app.Component("/", func(w http.ResponseWriter, r *http.Request) {
w.Header().Add("Content-Type", "text/html")
views.Component().Render(context.Background(), w)
})
app.Listen(":3000")
}

This may not be the only issue, but I can see that you are writing to the response before setting headers, you should set the header in the middleware.

@joerdav Thank you for your help, but I figured out what I actually had to do, what I wanted is to intercept the reponse, so I had to first run the next handler than modify the response if it is html, but thank you man.
