how to remove X-Powered-By in ExpressJS [duplicate]
Don't remove it; ask Express not to generate it in the first place:

Go to your app.js and just after:
var app = express();Add:
app.disable('x-powered-by');
The better way to do it is:
app.disable('x-powered-by');You can also make a middleware to remove any header like so:
app.use(function (req, res, next) { res.removeHeader("X-Powered-By"); next();});See more info on how to remove a header:

Middleware snippet from: Can't get rid of header X-Powered-By:Express
function customHeaders( req, res, next ){ // Switch off the default 'X-Powered-By: Express' header app.disable( 'x-powered-by' ); // OR set your own header here res.setHeader( 'X-Powered-By', 'Awesome App v0.0.1' ); // .. other headers here next();}app.use( customHeaders );// ... now your code goes here
