Find repository dependencies in all your projects

find-repo-dependencies.js

// Usage : node find-repo-dependencies /path/to/projects/folder
const path = require('path');
const fs = require('fs');

const folder = path.resolve(process.argv[2]);

fs
  .readdirSync(folder)
  // Absolute path
  .map(item => path.join(folder, item))
  // Folders only
  .filter(item => fs.statSync(item).isDirectory())
  // Look for package.json
  .map(item => path.join(item, 'package.json'))
  .filter(fs.existsSync)
  // Parse package.json
  .map(item => JSON.parse(fs.readFileSync(item, 'utf8')))
  // Merge dependencies
  .map(item => ({
    name: item.name,
    dependencies: {
      ...(item.dependencies || {}),
      ...(item.devDependencies || {}),
    },
  }))
  // Find ssh/github/gitlab dependencies
  .map(item => ({
    ...item,
    dependencies: Object.entries(item.dependencies)
      .filter(entry => entry[1].includes('/'))
      .map(entry => ({ name: entry[0], url: entry[1] })),
  }))
  // With at least one repository dependency
  .filter(item => item.dependencies.length)
  // Print
  .forEach(item =>
