Express.js vs Nest.js: The Battle of Backend Frameworks

Dipraj Girase — Tue, 25 Mar 2025 12:01:42 +0000

When it comes to backend development, Node.js with Express has long been the go-to choice. It's fast, lightweight, and event-driven a solid foundation for web applications.

But then came Nest.js, built on top of Node.js and Express, with a structured, opinionated approach that brings enterprise-level organization to backend development.

So, is Nest.js just Express in a fancy outfit, or is it a game-changer? Let’s break it down.

Node.js: The Backbone

Think of Node.js as that dependable friend—always there when you need a quick server setup or a lightweight backend.

🔹 Speed & Scalability – Perfect for real-time applications.
🔹 Flexibility – Lets you build things your way.
🔹 Minimalistic – No unnecessary overhead.

But there’s a catch.

🛑 No built-in structure – You have to organize your code manually.
🛑 Callback Hell – Though async/await made life easier, deep nesting is still a challenge.
🛑 Boilerplate Code – Every major feature requires external packages and manual setup.

Pair Node.js with Express.js, and you get a powerful but unopinionated framework. It’s like a blank canvas—you decide how to structure your app. But too much freedom often leads to spaghetti code if not managed properly.

Nest.js: The Fancy Cousin with a Plan

Enter Nest.js a TypeScript-powered, decorator-heavy framework that brings order to chaos.

🔹 Built-in Structure – Organizes your backend neatly with controllers, modules, and services.
🔹 Dependency Injection (DI) – No need to manually manage dependencies.
🔹 TypeScript-First – Prevents runtime errors with strong type safety.

Sure, it feels opinionated at first, but soon you’ll realize—it’s scaffolding for scalable applications.

Why Developers Love Nest.js:

✅ Minimal Boilerplate – Features like authentication, database connections, and validation are already streamlined.
✅ Swagger Integration – Auto-generates API documentation with decorators like @ApiBearerAuth().
✅ Enterprise-Grade – Ideal for large applications requiring scalability and maintainability.

TypeScript: The Unsung Hero

Node.js lets you choose between JavaScript and TypeScript, but Nest.js fully embraces TypeScript from the start.

✔ Static Typing – Reduces bugs by catching errors at compile time.
✔ DTOs & Interfaces – Clearly defines request and response structures.
✔ Better Code Maintenance – Large teams benefit from strict typings and modular architecture.

Yes, writing TypeScript feels like doing taxes at first, but the long-term benefits outweigh the initial learning curve.

Decorators: The Sparkle That Sticks

Nest.js decorators simplify backend logic by making everything more readable and structured.

🔹@Controller() – Defines route controllers.
🔹 @Injectable() – Marks services for dependency injection.
🔹 @Module() – Organizes related components into logical modules.

It’s like using LEGO blocks—each piece fits perfectly into place.

Swagger Wars: Nest.js vs. Express.js

One of Nest.js’s biggest wins? Effortless Swagger integration.

✔ Nest.js: Just add a few decorators, and Swagger automatically documents your API.
❌ Express.js: Swagger setup is manual—you’ll often need to define schemas yourself.

LiveAPI: Swagger for the Rest of Us
But what if you're using plain Node.js or Express and want easy API documentation without manual setup?

Introducing LiveAPI—a tool that auto-generates API docs in minutes, even for raw Node.js projects.

How it works:

1️⃣ Select your repository.
2️⃣ Wait 2–3 minutes.
3️⃣ Get fully structured API documentation—zero manual effort.

Conclusion:

Which One Should You Choose?
🔹 Choose Node.js (Express.js) if you want flexibility and control, but don’t mind handling structure and boilerplate yourself.
🔹 Choose Nest.js if you prefer a structured, scalable, and maintainable backend with built-in best practices.

Either way, npm install sanity before diving in. 😉

So, what’s your pick-classic Node.js or the well-dressed Nest.js?

Optimize Your CSS and Improve Performance with PurgeCSS

Dipraj Girase — Sat, 01 Mar 2025 07:26:30 +0000

When building web applications, we often rely on our go-to CSS frameworks like Bootstrap or TailwindCSS. These frameworks are packed with useful utilities that help speed up our development process and normalize our UI across browsers. However, they also come with a lot of bloat — a significant portion of the framework's CSS often goes unused in most projects.

Even if you build and maintain your own Design System from scratch, you’ll still end up with unused CSS across different projects. This is where PurgeCSS becomes incredibly useful.

What is PurgeCSS?
PurgeCSS is a powerful tool that helps remove unused CSS, leaving you with a leaner, faster stylesheet that only contains the styles your project actually uses. In my personal projects, after integrating PurgeCSS, I’ve seen CSS file size reductions of 70% to 90%, along with noticeable performance improvements in render times.

Compatibility & Usage
PurgeCSS works well with most modern JavaScript bundlers and web build tools. It also offers a CLI tool for direct use. Personally, my favorite setup is using PurgeCSS with TailwindCSS in Next.js projects, where the integration is seamless.

Example & Guide
If you're looking for a practical example, here’s a helpful guide along with a GitHub repository I created when I was experimenting with PurgeCSS and TailwindCSS. It walks through my setup and shows how easy it is to get started.

👉 Check out PrugeCSS for more details.

Recommended Reading
I also recently came across an excellent article on freeCodeCamp titled "How I dropped 250KB of dead CSS weight with PurgeCSS" It offers some great insights into real-world improvements you can achieve with PurgeCSS — highly recommended!

Final Thoughts
Whether you’re working on small projects or large-scale applications, optimizing your CSS footprint is critical for performance. Tools like PurgeCSS make this process simple and highly effective.

Have you used PurgeCSS in your projects? I’d love to hear about your experience!
