bunfile

A BunFile represents a lazily-loaded file; initializing it does not actually read the file from disk.

Note from Bun — The Bun.file and Bun.write APIs documented on this page are heavily optimized and represent the recommended way to perform file-system tasks using Bun. For operations that are not yet available with Bun.file, such as mkdir or readdir, you can use Bun’s nearly complete implementation of the node:fs module.
