Write a Blob to a file

Use Bun.write() to write a Blob to disk. The first argument is a destination, like an absolute path or BunFile instance. The second argument is the data to write.

const path = "/path/to/file.txt";
const data = new Blob(["Lorem ipsum"]);
await Bun.write(path, data);

The BunFile class extends Blob, so you can pass a BunFile directly into Bun.write() as well.

const path = "./out.txt";
const data = Bun.file("./in.txt");

// write the contents of ./in.txt to ./out.txt
await Bun.write(path, data);

See Bun.write().
