EJS Layouts

This lesson covers EJS Layouts. If this feels new, that is normal. We will build up slowly.

What you will learn

What ejs layouts means — in normal words, not textbook words
How it works step by step
Code you can run today on your laptop
Where teams use this in real projects

Before you start

Software: Node.js LTS from nodejs.org, VS Code, and a terminal
Knowledge: Earlier lessons in this Node.js course
Previous lesson: EJS Basics — Complete Guide

Explain it simply

Layouts wrap pages in shared header and footer so you do not copy the same HTML on every template.

Think of it like this: Express is like a reception desk: every visitor (HTTP request) is checked, directed to the right room (route), and sent back with an answer (response).

Why developers use this

Core skill for web backends
Huge community and docs
Leads to REST and auth

How it works (step by step)

A browser or app sends an HTTP request to your server.
Express middleware runs in order (log, parse JSON, check auth).
The route handler for EJS Layouts runs your logic.
You send JSON or HTML back with the right status code (200, 201, 404, 500).

Code example — type this yourself

<!-- layout.ejs -->
<body><%- include('partials/header') %><%- body %><%- include('partials/footer') %></body>

Use partials for nav and footer. Packages like express-ejs-layouts simplify the pattern.

What each part does

 — Line 1: runs as written.
<body><%- include('partials/header') %><%- body %><%- include('partials/footer') %></body> — Line 2: runs as written.

Real life: where EJS Layouts shows up

A college admin panel uses EJS Layouts with Express: students hit /courses, teachers hit /grades, and shared middleware checks login once for every page.

Try it yourself — hands-on

Create a new file (e.g. ejs-layouts-demo.js) in an empty folder
Type the example code for EJS Layouts yourself — typing helps memory
Run node on that file and read the output
Change one line (a value, a message, a route path) and run again to see what breaks or improves

Tip: After this lesson, close your editor and explain EJS Layouts in one sentence without looking.

Common mistakes (avoid these)

Skipping the terminal — EJS Layouts only feels easy after you run code yourself.

Pro tip (intermediate): In team projects, document how your team uses EJS Layouts in the README so new developers onboard faster.

Interview note

Be ready to explain EJS Layouts with a real trade-off: what problem it solves and what you would not use it for.

Summary

You can explain EJS Layouts in your own words
You ran working code — not just read about it
You know one mistake to avoid and one real place teams use this
