To write a `ReadableStream` to disk, call `.writer()` on a `BunFile` to get a [`FileSink`](/runtime/file-io#incremental-writing-with-filesink). The stream is an async iterable, so write each of its chunks to the `FileSink` with `for await`. Then call `.end()` to flush the buffer and close the file.
|

|
|
|
||
|
|
```ts
|
||
|
|
const stream: ReadableStream = ...;
|
||
|
|
const path = "./file.txt";
|
||
|
|
const writer = Bun.file(path).writer();
|
||
|
|
|
||
|
|
for await (const chunk of stream) {
|
||
|
|
writer.write(chunk);
|
||
|
|
}
|
||
|
|
|
||
|
|
await writer.end();
|
||
|
|
```

`.writer()` creates the file if it doesn't exist, but does not truncate an existing file. If the file may already exist, delete it first.
