使用purr遍历文件目录列表以读取文件所在的最大子文件夹

const purr = require('purr');

function traverseDirectory(directoryPath) {
  let maxSubfolder = '';
  let maxFileCount = 0;

  purr.readdir(directoryPath, (err, files) => {
    if (err) {
      console.error(err);
      return;
    }

    files.forEach((file) => {
      const filePath = directoryPath + '/' + file;

      purr.stat(filePath, (err, stats) => {
        if (err) {
          console.error(err);
          return;
        }

        if (stats.isDirectory()) {
          const subfolderFileCount = traverseDirectory(filePath);

          if (subfolderFileCount > maxFileCount) {
            maxFileCount = subfolderFileCount;
            maxSubfolder = filePath;
          }
        }
      });
    });
  });

  return maxFileCount;
}

const directoryPath = '/path/to/directory';
const maxFileCount = traverseDirectory(directoryPath);

console.log('最大子文件夹路径：', maxSubfolder);
console.log('最大子文件夹文件数量：', maxFileCount);
