Check Your Understanding

What does "view engine" do?

Where does it go in an express app?

How do I tell the server where to find views?

Rendering Templates

<body>
<h1><%= title %></h1>
<ul>
<% for(var i=0; i<supplies.length; i++) {%>
   <li><%= supplies[i] %></li>
<% } %>
</ul>
var express = require('express');
var router = express.Router();

router.get("/", function(req,res) {
    res.render("puppies", puppyData)
});

views/puppies.ejs

controllers/puppies.js
