Compare different package.json files in a monorepo to see if dependency versions differ

check-packages.js

const chalk = require("chalk");

const packages = [
  require("./package.json"),
  require("./packages/cec-scripts/package.json"),
  require("./packages/generator-cec/package.json"),
  require("./packages/utility-cec-simulator/package.json")
];

const compareDeps = p => {
  console.log(`Comparing ${chalk.cyan(p.name)}`);
  console.log();

  const pDependencies = {
    ...(p.dependencies || {}),
    ...(p.devDependencies || {})
  };

  for (const p2 of packages) {
    if (p2.dependencies) {
      const p2Dependencies = {
        ...p2.dependencies,
        ...p2.devDependencies
      };

      for (const d of Object.keys(p2Dependencies)) {
        if (pDependencies[d] && pDependencies[d] !== p2Dependencies[d]) {
          console.log(`* Dependency ${chalk.yellow(d)} differs:
  ${chalk.cyan(p.name)}: ${chalk.green(pDependencies[d])}
  ${chalk.cyan(p2.name)}: ${chalk.green(p2Dependencies[d])}`);
        }
      }
    }
  }
  console.log();
  console.log();
};

while (packages.length > 0) {
  console.log();
  const p = packages.pop();

  compareDeps(p);
}

great script. thank you

love it man
