Write a Response to a file with Bun

This code snippet writes a Response to disk at a particular path. Bun will consume the Response body according to its Content-Type header.

It uses the fast Bun.write() API to efficiently write data to disk. 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.sh");
const path = "./file.txt";
await Bun.write(path, result);

See Docs > API > File I/O for complete documentation of Bun.write().
