How to delete a folder from nodejs?

Node.js deletes folders and files:

Node.js 's fs module only provides the function of deleting file unlink folder and directory rmdir, so we need to delete it through traversal. The code is as follows

Var fs = require ('fs'); / / introduce fs module 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 ()) {/ / recursedeleteall (curPath);} else {/ / delete filefs.unlinkSync (curPath);}); fs.rmdirSync (path);}

Use

Deleteall (". / dir") / / just pass in the folder

Update:

Haha, I found a more convenient code to use the ability of nodejs to call system commands and use system commands to delete. I used commands in npm run xxx to delete, but due to compatibility problems 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);}}); at this point, the study on "how nodejs deletes folders" is over, hoping to solve everyone's doubts.
