node.js - Partial Load in express and pug without reloading the layout.pug -

is possible layout.pug not refreshing on page switch example /page1 or /page2 ?

layout.pug:

doctype html html     head         title pug example         meta(name="viewport" content="width=device-width, initial-scale=1")         script(src="/js/vendor/jquery.min.js")      body         div.container             h1#test= 0             script.                 var count = 0;                 setinterval(function() {                     count++;                     $('#test').text(count);                     console.log(count);                 },1000);              block content 

page1.pug:

extends layout block content     .row         .col-md-8             p page 1             a(href='/test2') link 

page2.pug:

extends layout block content     .row         .col-md-8             p page 2             a(href='/test1') link 

on every switch /page1 or /page2 script should not reset , content should rendered.

express:

app.get('/page1', function(req, res) {     res.render('page1', { user: req.user }) });  app.get('/page2', function(req, res) {     res.render('page2', { user: req.user }) }); 

is possible express , pug atleast or need additional packages??
