#How to delete a folder in nodejs?

node.js Delete folders and files:

The fs module of node.js only provides the function of deleting the file unlink folder and directory rmdir, so delete them together. We need to traverse and delete, the code is as follows

var fs = require('fs'); // 引入fs模块
 
function deleteall(path) {
var files = [];
if(fs.existsSync(path)) {
files = fs.readdirSync(path);
files.forEach(function(file, index) {
var curPath = path + "/" + file;
if(fs.statSync(curPath).isDirectory()) { // recurse
deleteall(curPath);
} else { // delete file
fs.unlinkSync(curPath);
}
});
fs.rmdirSync(path);
}
};

Use

deleteall("./dir")//将文件夹传入即可

Update:

Haha, I found a more convenient code to use nodejs to call system commands Ability to use system commands to delete. I used to use npm run xxx in xxx to delete. However, due to compatibility issues with different commands in the system, I have to come to nodejs to judge the system

var exec = require('child_process').exec;
var cmdStr = 'rm -rf xxhbg_app_src/webapp';
exec(cmdStr, function (err, stdout, srderr) {
  if (err) {
    console.log(srderr);
  } else {
    console.log(stdout);
  }
});
