EJS vs Pug vs Handlebars in Express: Key Differences & Usage
EJS offers simple HTML-like templates, Pug uses indentation-based syntax for cleaner code, and Handlebars provides powerful logic-less templates with helpers. Choose based on your preference for syntax style and template complexity.Quick Comparison
Here is a quick overview comparing EJS, Pug, and Handlebars on key factors.
| Factor | EJS | Pug | Handlebars |
|---|---|---|---|
| Syntax Style | HTML-like with <% %> tags | Indentation-based, minimal syntax | HTML-like with {{ }} expressions |
| Logic in Templates | Allows JavaScript code | Limited logic, mostly tags | Logic-less, uses helpers |
| Learning Curve | Easy for HTML users | Steeper due to new syntax | Moderate, simple expressions |
| Template Readability | Verbose but familiar | Clean and concise | Clear but can be verbose |
| Extensibility | Supports JavaScript freely | Supports mixins and includes | Strong helper system |
| Community & Support | Very popular, mature | Popular, especially in Node.js | Popular with strong ecosystem |
Key Differences
EJS templates look like regular HTML files with embedded JavaScript code inside <% %> tags. This makes it very familiar and easy to start if you know HTML and JavaScript. You can write any JavaScript logic directly in the template, which gives flexibility but can lead to cluttered templates.
Pug uses indentation instead of HTML tags to define structure, which makes templates shorter and cleaner. It avoids closing tags and uses a minimal syntax, but this requires learning a new style. Pug limits logic inside templates to keep them clean and encourages using mixins and includes for reusable parts.
Handlebars focuses on being logic-less, meaning templates contain only expressions like {{variable}} and helpers for formatting or conditions. This separation keeps templates clean and easier to maintain. Handlebars has a strong helper system to extend functionality without embedding JavaScript directly in templates.
Code Comparison
Here is how you render a simple greeting message with a variable name in EJS:
<!DOCTYPE html> <html> <head> <title>Greeting</title> </head> <body> <h1>Hello, <%= name %>!</h1> </body> </html>
Pug Equivalent
The same greeting in Pug looks like this:
doctype html
html
head
title Greeting
body
h1 Hello, #{name}!When to Use Which
Choose EJS if you want simple, straightforward templates that look like HTML and allow JavaScript directly for quick development.
Choose Pug if you prefer clean, minimal syntax and don't mind learning indentation-based templates for more readable code.
Choose Handlebars if you want to keep templates logic-free and maintain a clear separation between HTML and JavaScript, especially for larger projects with reusable helpers.
