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.
To read the file into a
Buffer instance, first use
.arrayBuffer() to consume the file as an
ArrayBuffer, then use
Buffer.from() to create a
Buffer from the
const path = "/path/to/package.json"; const file = Bun.file(path); const arrbuf = await file.arrayBuffer(); const buffer = Buffer.from(arrbuf);
Refer to Binary data > Buffer for more information on working with
Buffer and other binary data formats in Bun.
