Using the following details in index.pug: (pug template) how can I implement this to handlebars node js view engine. Others are working fine but I don't know how to implement the previous and next page.

extends layout

block content
body
br
br
br
.container
ul.list-group
each post, i in posts
li.list-group-item
a(href="/posts/" + posts._id)= posts.title
ul
if current > 1
li
a(href=`?page=${parseInt(current) - 1}`) Previous
- var i = 1
while i <= pages
li
a(href=`?page=${i}`)= i++
if current < pages
li
a(href=`?page=${parseInt(current) + 1}`) Next
