Set server timeout in express.js

var timeout = express.timeout // express v3 and below
var timeout = require('connect-timeout'); //express v4

app.use(timeout(120000));
app.use(haltOnTimedout);

function haltOnTimedout(req, res, next){
   if (!req.timedout) next();
}

Or without other modules

app.use(function(req, res, next){
   res.setTimeout(120000, function(){
      console.log('Request has timed out.');
         res.send(408);
      });

      next();
 });
