@nodesecure/fs-walk v2.0.0

Modern FileSystem (fs) utilities to lazy walk directories Asynchronously (but also Synchronously). Under the hood the code has been created using ES6 Generators.

Features

• Lazy walk by using fs.opendir.
• Zero dependencies.
• Enforce usage of Symbols for CONSTANTS.
• Synchronous API.

!NOTE Performance over some of the features is a non-goal.

Requirements

• Node.js v18 or higher

Getting Started

This package is available in the Node Package Repository and can be easily installed with npm or yarn.

$ npm i @nodesecure/fs-walk
# or
$ yarn add @nodesecure/fs-walk

Usage example

import path from "node:path";
import { walk } from "@nodesecure/fs-walk";

for await (const [dirent, absoluteFileLocation] of walk(".")) {
  if (dirent.isFile()) {
    console.log(absoluteFileLocation);
    console.log(path.extname(absoluteFileLocation));
  }
}

API

export interface WalkOptions {
  extensions?: Set<string>;
}

export type WalkEntry = [dirent: fs.Dirent, absoluteFileLocation: string];

walk(directory: string, options?: WalkOptions): AsyncIterableIterator< WalkEntry >

Asynchronous walk.

walkSync(directory: string, options?: WalkOptions): IterableIterator< WalkEntry >

Synchronous walk (using readdirSync under the hood instead of opendir).

For example fetching JavaScript files for a given location:

import { walkSync } from "@nodesecure/fs-walk";

const javascriptFiles = [...walkSync("./someDirectory", { extensions: new Set([".js"]) }))]
    .filter(([dirent]) => dirent.isFile())
    .map(([, absoluteFileLocation]) => absoluteFileLocation);

console.log(javascriptFiles);
