ReadableStream issue with other libraries

[younes200]

Hi
@expo/server use @remix-run/node@2.7.2 as part of the server api handling, my issue is with @remix-run/web-stream which I understand doesn't use native fetch and cause incompatibility other library with ReadableStream. like :

https://github.com/vercel/ai/blob/4d458dfd1806e793b7b14acddb56ff48517b3b41/packages/provider-utils/src/response-handler.ts#L98

The error being raised is:

TypeError: First parameter has member 'readable' that is not a ReadableStream.
    at assertReadableStream (/Users/x/test-ai/node_modules/web-streams-polyfill/src/lib/validators/readable-stream.ts:5:11)
    at convertReadableWritablePair (/Users/x/test-ai/node_modules/web-streams-polyfill/src/lib/validators/readable-writable-pair.ts:15:3)
    at ReadableStream.pipeThrough (/Users/x//test-ai/node_modules/web-streams-polyfill/src/lib/readable-stream.ts:223:23)

Is there a way for solve the issue ?

Solution, in vite.config.ts:

installGlobals({ nativeFetch: true })

Pass this option in the remix vite plugin to fix the issue:

remix({
    future: {
        v3_singleFetch: true,
    },
})
