如何在nodejs中获得文件夹大小，并排除带有全局模式的某些路径？

const fs = require('fs');
const path = require('path');

function getFolderSize(folderPath, excludePatterns) {
  let totalSize = 0;

  function calculateSize(filePath) {
    const stats = fs.statSync(filePath);

    if (stats.isFile()) {
      totalSize += stats.size;
    } else if (stats.isDirectory()) {
      const files = fs.readdirSync(filePath);
      files.forEach(file => {
        const fullPath = path.join(filePath, file);
        if (!excludePatterns.some(pattern => fullPath.match(pattern))) {
          calculateSize(fullPath);
        }
      });
    }
  }

  calculateSize(folderPath);

  return totalSize;
}

const folderPath = '/path/to/folder';
const excludePatterns = [/pattern1/, /pattern2/]; // 使用正则表达式定义要排除的路径模式

const folderSize = getFolderSize(folderPath, excludePatterns);
console.log(`文件夹大小: ${folderSize} 字节`);
