global is not defined

[binajmen]

With Prisma, it is recommended in development to keep a copy of the prisma client in global. This is a best practive applied in other frameworks such as Next or Remix:

...
declare global {
  var __db__: PrismaClient;
}

// this is needed because in development we don't want to restart
// the server with every change, but we want to make sure we don't
// create a new connection to the DB with every change either.
// in production we'll have a single connection to the DB.
if (process.env.NODE_ENV === "production") {
  prisma = getClient();
} else {
  if (!global.__db__) { // <--- this is line 17
    global.__db__ = getClient();
  }
  prisma = global.__db__;
}
...

But I get the following error in console:

prisma.ts:17 Uncaught ReferenceError: global is not defined
    at prisma.ts:17:3

I believe this comment vitejs/vite#2618 (comment) is part of the response, but it is unclear how to fix that. I suppose there should be a workaround to have such best practice applied with SolidStart.

This happens when I create the following route action:

...
export default function Index() {
  const users = useRouteData<typeof routeData>();

  const [_, { Form }] = createRouteAction(async (formData: FormData) => {
    const email = formData.get("email");
    await prisma.user.create({
      data: {
        email: email as string,
      },
    });
  });
...

I suppose the bundling of the route action happens before the declare global, thus the error.

My bad, I know why! createServerAction$ for the win!
