复制文件并用NodeJS替换变量

const fs = require('fs');

function replaceVariables(sourcePath, destinationPath, variables) {
  // 读取源文件内容
  const sourceContent = fs.readFileSync(sourcePath, 'utf8');
  
  // 替换变量
  let replacedContent = sourceContent;
  for (const variable in variables) {
    const value = variables[variable];
    const regex = new RegExp(`{{${variable}}}`, 'g');
    replacedContent = replacedContent.replace(regex, value);
  }
  
  // 写入目标文件
  fs.writeFileSync(destinationPath, replacedContent);
}

// 定义需要替换的变量及其对应的值
const variables = {
  projectName: 'My App',
  author: 'John Doe',
  date: '2022-01-01',
};

// 调用函数复制文件并替换变量
replaceVariables('source/file.txt', 'destination/file.txt', variables);
