### 使用node打印所选文件夹目录列表，并生成一个readme.md文件 const path = require('path'); const fs = require('fs'); let target = path.join(__dirname, process.argv[2] || "./"); let jsonText = '\n\n'; function onreadFile(target, deep) { const dirInfo = fs.readdirSync(target); let level = new Array(deep + 1).join('│ '); let dir = []; let files = []; dirInfo.forEach(item => { let stat = fs.statSync(path.join(target, item)); if (stat.isDirectory()) { dir.push(item); } else { files.push(item); } }); let len = deep + 1; dir.forEach(item => { console.log(`${level}├─${item}`); jsonText += `${level}├─${item}` + '\n'; onreadFile(path.join(target, item), len); }) files.forEach((item, index) => { if (index == (files.length - 1)) { console.log(`${level}└─${item}`); jsonText += `${level}└─${item}` + '\n'; } else { console.log(`${level}├─${item}`); jsonText += `${level}├─${item}` + '\n'; } }) if (dir.length <= 0) { let timer = setTimeout(() => { fs.writeFile('./readme.md', jsonText, function (err) { console.log(err); }); clearTimeout(timer); }, 0) } } onreadFile(target, 0);
