Best way to enhance form actions with type safety?

[diericx]

Hello, I am currently implementing enhanced form actions like so in a +page.server.ts file:

export const enhancedFormAction = (next: Action) => {
  return async function(context) {
        // logic that eventually wants to pass some data through
        return await next({ ...context, formData })
  }
}

export const actions: Actions = {
  new: enhancedFormAction((async ({ request, fetch, formData }) => {
    // form action content that wants to use data from enhance function
  })
}

Currently there is no type safety for this; the formData throws a ts error. Is there any way to do this with type safety? Is this poor design?
