method FileHandle.readableWebStream
Unstable
Usage in Deno
```typescript import { type FileHandle } from "node:node__fs--promises.d.ts"; ```
FileHandle.readableWebStream(options?: ReadableWebStreamOptions): ReadableStream
Returns a `ReadableStream` that may be used to read the files data.
An error will be thrown if this method is called more than once or is called
after the `FileHandle` is closed or closing.
```js
import {
open,
} from 'node:fs/promises';
const file = await open('./some/file/to/read');
for await (const chunk of file.readableWebStream())
console.log(chunk);
await file.close();
```
While the `ReadableStream` will read the file to completion, it will not
close the `FileHandle` automatically. User code must still call the`fileHandle.close()` method.
