Write a Response to a file

Save the body of a Response, such as a fetch result, to a file with Bun.write().

Use Bun.write() to write a Response to disk. Bun writes the body of the Response to the destination.

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

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