node.js - express - render multiple views

Question

I'ld like to send two successive ejs page to the client using the following code:

app.post('/', function(req,res) {
  res.render('yourDemandIsBeingProceed.ejs');
  //some code which require time (open an external programm, run a script, edit a response)
  res.render('hereIsYourResult.ejs');
  res.end();
});

So, once once the client post his form, he receives a page asking him to wait for a few seconds and then the page containing the response is send.

any suggestion?

many thx

This is not how http works. Once you execute res.render the connection is closed and you cannot send any more data to the client. — Amberlamps

What you can do is have client-side code in yourDemandIsBeingProceed.ejs when the page loads that performs a get/post request to a different endpoint. When the result from that is received, hide/show different elements inside yourDemandIsBeingProceed.ejs so it looks more like hereIsYourResult.ejs

What you really should do is have the user submit information via front end AJAX and put up a loading graphic until the JSON response gets back. AJAX was developed for situations exactly like this.
