formAction$ appears not to bundle correctly

[imMadsen]

Found this issue when trying to integrate drizzle using the following guide.

The problem is when using the database connection within a formAction$ like in the following example

formAction$<LoginForm>(() => {
  const sql = postgres("postgresql://postgres:mysecretpassword@127.0.0.1:5432/cupon");
  const db = drizzle(sql);
}, valiForm$(LoginSchema));

One will get this error (Full log can be found here). It is my understanding from the documentation that formAction$ is executed on the server. Note that executing the same function within a server$, for an example will not lead to any issues. The error will also only occur when building the qwik app.

A temporary solution I've found is simply using the server$, and passing it as the function for the formAction$, but this will make TypeScript pretty mad.

export const myFunction = server$(async (args: any) => {
  const sql = postgres("postgresql://postgres:mysecretpassword@127.0.0.1:5432/cupon");
  const db = drizzle(sql);
})

// @ts-ignore typescript get very mad 😢
export const useFormAction = formAction$<LoginForm>(myFunction, valiForm$(LoginSchema));

This is a known issue that I plan to address in the coming months. See this issue. As a workaround, I recommend wrapping all of your formAction$ code in isServer:

formAction$<LoginForm>(() => {
  if (isServer) {
    const sql = postgres("postgresql://postgres:mysecretpassword@127.0.0.1:5432/cupon");
    const db = drizzle(sql);
  }
}, valiForm$(LoginSchema));

After hours of debugging, I found this issue to be the root cause of too much being bundled for the client in my application.
Would love to see this solved.

The workaround works. I prefer the early return pattern, though:

formAction$<LoginForm>(() => {
  if (isBrowser) return;
  // ...
}, valiForm$(LoginSchema));

With this workaround I still get a warning that node:async_hooks has been externalized for browser compatibility. But this does not seem to impact the application.

Hello, here is a repo with simple reproduction: https://github.com/rafalfigura/qwik-bundles-pg-in-client-dist
The method with isServer/isBrowser works as expected but still there is one warning with node:async_hooks like @svi3c pointed

I've also tried to migrate from pg to mysql2 and it still had the same issue.

I am very sorry about this problem. I still plan to submit a PR to Qwik and fix this. I hope to have time to do this by the end of the year.

Thanks for sharing solutions, this worked for me in the meantime:

if (isBrowser) throw new Error('...')

Any progress on this? I stumbled on this issue with prisma.
Here is my minimal reproduction repo:
https://github.com/vsDizzy/qwik-prisma

I believe two things should be changed in docs about Modular Forms integration:

1. Modular Forms should be installed as a dev dependency:

-pnpm install @modular-forms/qwik
+pnpm install @modular-forms/qwik -D

2. isBrowser should be used to mark server code:

export const useFormAction = formAction$<LoginForm>((values) => {
+  if (isBrowser) throw new Error()
  // Runs on server
}, valiForm$(LoginSchema));
