Address:

Welcome to fork or star

Principle:

Mainly uses the node.js file operation method

fs.existsSync(path) Returns true if the file exists, otherwise returns false
fs.statSync(dir) Returns the related attributes of dir
fs.readdirSync(dir) Returns a file that does not include '.' and '..' array of file names
fs.unlinkSync(file) Delete file
fs.rmdirSync(dir) Delete folder

Main code:

if( fs.existsSync(dir) ) {
    if(fs.statSync(dir).isDirectory()) {
        files = fs.readdirSync(dir);
        files.forEach(function(file,index){
            var curPath = path.join(dir,file);
            if(fs.statSync(curPath).isDirectory()) {
                run(curPath);   
            } else { 
                fs.unlinkSync(curPath);
            }
        });
        fs.rmdirSync(dir);
    } else {
        fs.unlinkSync(dir);
    }
}
