Read a file as a ReadableStream - Bun

The Bun.file() function accepts a path and returns a BunFile instance. The BunFile class extends Blob and allows you to lazily read the file in a variety of formats. Use .stream() to consume the file incrementally as a ReadableStream.

const path = "/path/to/package.json";
const file = Bun.file(path);

const stream = file.stream();

The chunks of the stream can be consumed as an async iterable using for await.

for await (const chunk of stream) {
  chunk; // => Uint8Array
}

Refer to the Streams documentation for more information on working with streams in Bun.
