Are you using Express with node js and want to get rid of "X-Powered-By" response header or you want to replace it with you domain name ???

all you need to do is just write a simple middleware. First we'll see how to remove it and then how to customize.

add this line of code to your app.js.

// x-powered by ionos
app.disable('x-powered-by'); //to disable

to modify you have to write a simple middle ware just like this.

// x-powered by 
app.use(function (req, res, next) {
    res.header('X-powered-by', 'geekinlinux')
    next();});

now try restarting node js service and refresh your webpage to see the changes.
