Installation

# npm
npm install @iohub/iter

# yarn
yarn add @iohub/iter

# pnpm
pnpm add @iohub/iter

Usage

import { iterDir, iterDoc, recurDir, recurDoc, recurLot } from '@iohub/iter'

// List files in a directory
for await (const file of iterDoc('src')) {
  console.log(file) // Yields file paths in src/
}

// List subdirectories
for await (const dir of iterDir('src')) {
  console.log(dir) // Yields directory paths in src/
}

// Recursively list all files
for await (const file of recurDoc('src')) {
  console.log(file) // Yields file paths in src/ and subdirectories
}

// Recursively list all directories
for await (const dir of recurDir('src')) {
  console.log(dir) // Yields directory paths in src/ and subdirectories
}

// Group files by directory
for await (const group of recurLot('src')) {
  console.log(group.dir) // Directory path
  console.log(group) // Array of files in directory
}

// Custom filtering and path transformation
const options = {
  doc: name => name.endsWith('.js'), // Filter files
  dir: name => !name.startsWith('.'), // Filter directories
  pipe: (name, dir) => `${dir}/${name}`, // Custom path joining
}

for await (const file of recurDoc.call(options, 'src')) {
  console.log(file) // Yields only .js files, skipping dot directories
}
