将递归文件夹中的多个缩小的javascript文件合并为一个文件

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

function mergeFiles(folderPath, outputFile) {
  const files = getAllJavaScriptFiles(folderPath);
  const mergedContent = mergeFileContents(files);
  writeMergedFile(outputFile, mergedContent);
}

function getAllJavaScriptFiles(folderPath) {
  let files = [];

  function traverseFolder(currentPath) {
    const items = fs.readdirSync(currentPath);

    items.forEach(item => {
      const itemPath = path.join(currentPath, item);
      const stat = fs.statSync(itemPath);

      if (stat.isDirectory()) {
        traverseFolder(itemPath);
      } else if (path.extname(itemPath) === '.js') {
        files.push(itemPath);
      }
    });
  }

  traverseFolder(folderPath);
  return files;
}

function mergeFileContents(files) {
  let mergedContent = '';

  files.forEach(file => {
    const content = fs.readFileSync(file, 'utf8');
    mergedContent += content + '\n';
  });

  return mergedContent;
}

function writeMergedFile(outputFile, content) {
  fs.writeFileSync(outputFile, content);
  console.log('Merged file created successfully!');
}

// 使用示例
const folderPath = '/path/to/folder';
const outputFile = '/path/to/output.js';
mergeFiles(folderPath, outputFile);
