Stream example in bun.sh docs has Typescript error

[thesmart]

What version of Bun is running?

1.1.13+bd6a60512

What platform is your computer?

Darwin 23.3.0 arm64 arm

What steps can reproduce the bug?

Take the stream example from the documentation:

const stream = new ReadableStream({
  start(controller) {
    controller.enqueue("hello");
    controller.enqueue("world");
    controller.close();
  },
});

for await (const chunk of stream) {
  console.info(chunk);
}

The code runs fine, but the stream symbol raises a typescript error in VSCode:

Type 'ReadableStream<any>' must have a '[Symbol.asyncIterator]()' method that returns an async iterator.ts(2504)

Here is my package.json, right out of bun init;

{
  "name": "foobar",
  "module": "index.ts",
  "type": "module",
  "devDependencies": {
    "@types/bun": "^1.1.4"
  },
  "peerDependencies": {
    "typescript": "^5.0.0"
  }
}

What is the expected behavior?

Type ReadableStream should support async iteration.

What do you see instead?

Type 'ReadableStream<any>' must have a '[Symbol.asyncIterator]()' method that returns an async iterator.ts(2504)

Add DOM.AsyncIterable to lib values in your tsconfig.json (eg.: "lib": ["ESNext", "DOM", "DOM.AsyncIterable"],)

Fixed in #18024. You can now use ReadableStream with or without DOM & Dom.AsyncIterable loaded.
