Filesystem (Node.js)

Usage

Maps data to the real filesystem using directory structure for nested keys. Supports watching using chokidar.

This driver implements meta for each key including mtime (last modified time), atime (last access time), and size (file size) using fs.stat.

import { createStorage } from "unstorage";
import fsDriver from "unstorage/drivers/fs";

const storage = createStorage({
  driver: fsDriver({ base: "./tmp" }),
});

Options:

• base: Base directory to isolate operations on this directory
• ignore: Ignore patterns for watch
• watchOptions: Additional chokidar options.

Node.js Filesystem (Lite)

This driver uses pure Node.js API without extra dependencies.

import { createStorage } from "unstorage";
import fsLiteDriver from "unstorage/drivers/fs-lite";

const storage = createStorage({
  driver: fsLiteDriver({ base: "./tmp" }),
});

Options:

• base: Base directory to isolate operations on this directory
• ignore: Optional callback function (path: string) => boolean
