Global Form Data Validation Handling

Form Validation

Instead of doing form validation in each page file, I'd like to do validation once via a "general form action" hook/function (via hooks.server.ts) and then let the request pass on to the specific route to work with the valid data.

However, I'm not quite sure how a page's export const actions: Actions relates to hook's export const handle: Handle = async ({ event, resolve }) => {} and how to add a general form handler in export const handle: Handle.

I.e.: User Input -> Data Validation, hooks.server.ts -> Data Use, Page.server.ts
