RSC Example doesn't work

[ricksmit3000]

Bug report

The RSC example from the examples folder doesn't work.

Description / Observed Behavior

The RSC example as is, throws an error when running it. When I await the request (const serverData = fetcher('http://localhost:3000/api/data') in page.jsx it does works.

Expected Behavior

I expect being able run the example without having to await the promise in the page component.

Repro Steps / Code Example

I cloned the RSC example run yarn install run yarn run dev navigate to localhost:3000/rsc I see TypeError: data.map is not a function.

Additional Context

SWR version: 2.2.5

You can run this example with pnpm dev.

I'm probably doing something run, but when I run it with pnpm dev I still get the same issue.

weird, I've also tried to "One-Click Deploy" this suspense example, and get the same error during build:

You might still use the latest version of SWR; the example depends on the feature that is contained in the beta versions. Did you clean your deps (node_modules/) and run pnpm install and pnpm build on the root before running the app?

Yeah, this example points to the latest version of SWR, so this won't work. https://github.com/vercel/swr/blob/main/examples/suspense/package.json#L10 I expect this will work after you update the version to "beta."

[koba04]

CONTRIBUTING.md will also help you.

[ricksmit3000]

Thanks for explaining! I've updated the package.json to use "beta" but that causes this error:
