Installation

npm install npx-scope-finder
# or
pnpm add npx-scope-finder
# or
yarn add npx-scope-finder

Usage

import { npxFinder } from 'npx-scope-finder';

// Basic usage - get raw package data
const packages = await npxFinder('@your-scope', {
  timeout: 10000,    // Request timeout in milliseconds (default: 10000)
  retries: 3,        // Number of retries for failed requests (default: 3)
  retryDelay: 1000   // Delay between retries in milliseconds (default: 1000)
});
console.log(`Found ${packages.length} executable packages`);

// Access package data
packages.forEach(pkg => {
  console.log(`Package: ${pkg.name}@${pkg.version}`);
  console.log(`Description: ${pkg.description || 'No description'}`);
  console.log('Executable commands:', Object.keys(pkg.bin || {}));
  
  // Access full original npm registry data
  console.log('Full package data:', pkg.original);
  
  // Access other metadata
  if (pkg.links?.repository) {
    console.log(`Repository: ${pkg.links.repository}`);
  }
  
  if (pkg.dependencies) {
    console.log('Dependencies:', Object.keys(pkg.dependencies).length);
  }
});

// Custom formatting example
packages.forEach(pkg => {
  const customFormat = `
    📦 ${pkg.name}@${pkg.version}
    ${pkg.description || 'No description'}
    Commands: ${Object.keys(pkg.bin || {}).join(', ')}
    Run with: npx ${pkg.name}
  `;
  console.log(customFormat);
});
