Getting the url parameters in an ejs template

Question

I am trying to create an ejs conditional based on a URL parameter, for example, if the test parameter exists at localhost:3000/page?test, then show a div, else dont show it.

Answer 1

just the send the stuff in the form of query which can be easily retrieved

app.get('/category', function(req, res) {
  var string = stuff
  res.redirect('/?valid=' + string);
}); 

In the ejs template you can directly use parameter name

<% var k = valid %>
