You can replace the contents of a file in node.js like so:

const fs = require('fs');

fs.writeFile("message.txt", "new content", (err) => {
    if (err) throw err;
    console.log('The file has been saved!');
});

It's not possible for code running in a browser, as this would constitute a major security risk.

Thank you so much but I'm trying to make a web app on my device only [without upload it to internet] is this methode suitable for my taget? – karam E Mar 07 '20 at 08:09
Does your app run in a web browser like Firefox, Chrome, or Internet Explorer? – Bastian Stein Mar 07 '20 at 10:02
Unfortunately No – karam E Mar 07 '20 at 18:13
How do you run it then? – Bastian Stein Mar 07 '20 at 18:27
By node.js but that is NOT satisfying enough so I decided to use PHP server with JavaScript Ajax. – karam E Mar 07 '20 at 19:46
