readStreamableValue | AI SDK Español

Warning

AI SDK RSC is currently experimental. We recommend using AI SDK UI for production. For guidance on migrating from RSC to UI, see our migration guide.

It is a function that helps you read the streamable value from the client that was originally created using createStreamableValue on the server.

Import

import { readStreamableValue } from "@ai-sdk/rsc"

Example

async function generate() {
  'use server';
  const streamable = createStreamableValue('');

  streamable.append('Hello');
  streamable.append(' ');
  streamable.append('World');
  streamable.done();

  return streamable.value;
}

import { readStreamableValue } from '@ai-sdk/rsc';

export default function Page() {
  const [generation, setGeneration] = useState('');

  return (
    <div>
      <button
        onClick={async () => {
          const stream = await generate();

          for await (const value of readStreamableValue(stream)) {
            setGeneration(value);
          }
        }}
      >
        Generate
      </button>
    </div>
  );
}
