About EJS

EJS (Embedded JavaScript templating) is a simple templating language that lets you generate HTML markup with plain JavaScript. It is commonly used in Node.js applications, especially with Express, to render views on the server side.

EJS syntax allows embedding JavaScript logic directly within HTML using <% %> delimiters.

Sample Code

The following is a sample EJS template that displays a personalized greeting:

<%
 let message = 'Hello, World!'
%>
<%= message %>

Syntax Basics

Output Data

• <%= %> — Outputs the value into the template (escaped)
• <%- %> — Outputs unescaped HTML

<p>Hello, <%= user.name %>!</p>
<%- include('footer') %>

Control Flow

• <% %> — Executes JavaScript logic without output

<% if (user.isLoggedIn) { %>
  <p>Welcome, <%= user.name %>!</p>
<% } else { %>
  <p>Please log in.</p>
<% } %>

Loops

<ul>
<% items.forEach(function(item) { %>
  <li><%= item %></li>
<% }); %>
</ul>

Partials (Includes)

<%- include('header') %>
<main>
  Content goes here
</main>
<%- include('footer') %>
