官网

const fs = require('fs');
const path = require('path');
const tinify = require('tinify'); // 需要安装 tinify 模块

// 设置 tinify API key
// https://tinypng.com/developers
tinify.key = '你的KEY';

async function compressFiles(dir, blackDirs = []) {
  const files = fs.readdirSync(dir);
  for (let i = 0; i < files.length; i++) {
    const file = files[i];
    const filePath = path.join(dir, file);
    const stat = fs.statSync(filePath);

    if (stat.isDirectory()) {
      if (blackDirs.indexOf(file) === -1) {
        await compressFiles(filePath, blackDirs);
      } else {
        console.log(`Skip directory: ${filePath}`);
      }
    } else if (/\.(png|jpe?g)$/i.test(filePath)) {
      console.log(`Compressing ${filePath}...`);
      const source = tinify.fromFile(filePath);
      await source.toFile(filePath);
    }
  }
}

function task(path) {
	const inputDir = path.resolve(__dirname, path);
	
	// 排除的文件夹名称，不用完整路径
	const blackDirs = []
	compressFiles(inputDir, blackDirs).then(() => {
	  console.log('All files compressed successfully!');
	}).catch((err) => {
	  console.error('Error occurred while compressing files:', err);
	});
}

// ====================
// 运行
const absolutePath = "目标目录完整路径(E:/images/xxx/)";
task(absolutePath);
