Use [`Bun.write()`](/runtime/file-io#writing-files-bun-write) to write a `Response` to disk. The body of the `Response` is written to the destination.

The first argument is a *destination*, like an absolute path or `BunFile` instance. The second argument is the *data* to write.

```ts
const result = await fetch("https://bun.com");
const path = "./file.txt";
await Bun.write(path, result);
```
