fs 模块常用例子

创建文件夹的例子

const fs = require('fs')
const path = require('path');
try {
  // 创建文件夹
  fs.mkdirSync('./abc')
} catch (err) {
  //
}
const paths = fs.readdirSync('./abc'); // 同步读取当前目录
paths.forEach(item => {
  console.log(item)
  // eslint-disable-next-line
  const __src = path.resolve(__dirname, './abc', item)
  console.log(__src)
  fs.stat(__src, function(err, stats) {
    if (err) {
      console.log(err)
    }
    if (stats.isFile()) { //如果是个文件则拷贝
      console.log('文件')
    } else {
      console.log('文件夹')
    }
  })
})

删除文件的例子

const fs = require('fs')
const path = require('path');
// eslint-disable-next-line
deleteFolder(path.resolve(__dirname, './abc'));
function deleteFolder (path) {
  let files = [];
  if (fs.existsSync(path)) {
    files = fs.readdirSync(path);
    files.forEach(function(file) {
      let curPath = path + '/' + file;
      if (fs.statSync(curPath).isDirectory()) {
        deleteFolder(curPath);
      } else {
        fs.unlinkSync(curPath);
      }
    });
    fs.rmdirSync(path);
  }
}
