javascript - Renaming files in a wordpress folder via jquery / jscript -

i trying run script run every 5 minutes in shared hostings wordpress folder rename newest csv file in folder.

/wp-content/csv/sample.csv 

i tried putting js file in folder within folder , run it.

var fs = require('fs');  function runclear()  {     fs.readdir("", (err, files) => {       files.foreach(file => {         console.log(file);       });     })     }  runclear(); setinterval(runclear, 300*1000); 

however, seems got client side , server side scripting confused. seems need node.js.

what best approach this?

regards,

yes right confused in client side , server side script.

javascript client side script deal user interactions happen user click or submit form, hover on element, scroll web page etc.

where server side script php deals data stored on server mysql records or physical files.

what trying change server resource client side script. , can not directly.

instead can call ajax function send http request script placed on server. , in server script write code read existing files in directory , rename them using file handling operations.
