How does the Static prerendering handle POST endpoints?

[HenrijsS]

This may seem a bit out there, but I was wondering: How does Static Prerendering handle POST endpoints (+page.server.js) files on a CDN?

I want to run a Sendgrid function with Environment Variables by submitting a form and I'm worried that it might expose the environment variables.

The site will be hosted on CloudFlare pages. Do endpoints invoke workers or do they function differently?

I believe if you use the private env modules, it will be difficult to accidentally expose environment variables.

Also, I don't think prerendering will have any affect on your form actions. Prerendering runs your load functions at build time and uses the values returned to build a html file for your page.

Does prerendering work on pages with actions? , I get this error whenever I try to prerender a page with actions.

Cannot prerender pages with actions
Error: Cannot prerender pages with actions

// page.server.ts

export const actions: Actions = {
  default: async ({ request }) => {
    const formData = await request.formData();

    const email = formData.get('email');
    const firstName = formData.get('firstName');
    const lastName = formData.get('lastName');
    const phoneNumber = formData.get('phoneNumber');

    if (email && firstName && lastName && phoneNumber) {
      return { success: true }
    }

    return { failure: true }

  }
}

export const prerender = true;

I just deployed my site on CloudFlare pages with adapter-auto and didn't specify the prerender = true attribute anywhere.
It all applies automatically and I still have no clue how it published endpoints.

Try removing the prerender. Also, where do you plan to host it?

Am using prerender = true in my root layout, but I get the error and am forced to prerender = false on any page with actions
And I plan to host it on Vercel. Using adapter-auto as well.
