How to retrieve params in `createServerAction$`?

Is there a clever way to retrieve the params in a createServerAction$ besides passing it as a parameter or FormData attribute?

  const [create, { Form }] = createServerAction$(async (formData: FormData) => {
    ...
  });

  const [create, { Form }] = createServerAction$(async (formData: FormData) => {
    ...
  });

does useParams() not work?

binajmenOP•2y ago

I don't think so. I can't use useParams() in server action, and if I declare it outside and try to use it, I get a closure issue (params not defined). Too bad we don't have access to params. We do have access to request though in the ActionEvent:

export function createRouteAction<T, U = void>(
  fn: (args: T, event: ActionEvent) => Promise<U>,
  options?: { invalidate?: Invalidate }
): RouteAction<T, U>;

export function createRouteAction<T, U = void>(
  fn: (args: T, event: ActionEvent) => Promise<U>,
  options?: { invalidate?: Invalidate }
): RouteAction<T, U>;

I wonder why we don't have params there.

In that case, you need the request object's url part parsed through new URL(). The resulting objects has searchParams as a property.

True 🙂 I wanted to be sure I don't miss something, I feel having params there would be handy 🙂

The same way we have access to request, it would be nice to have access to params as well: -const [create, { Form }] = createServerAction$(async (formData: FormData, { request }) => { +const...

I feel I spammed the discussions section recently, but I spent the weekend trying Solid. Loving it so far! Except the i18n. I didn't manage to make the primitives package work around SolidStart... yet!
