/** ESM / Typescript */
import { readFileSync } from 'fs';
import latestVersion from '@badisi/latest-version';

(async () => {
    // Single package
    const pkg = await latestVersion('npm');

    // List of packages

})();

$ latest-version <packageJson|packageName...>

  Examples:
    $ lv
    $ latest-version path/to/package.json
    $ latest-version package1 package2 package3 --skip-missing
