Modern Web Stack Selection: Next.js, TypeScript, and Tailwind

Introduction

Every new web project begins with a decision: Which technologies will we use?

The answer to this question directly affects the project's lifespan, maintenance cost, and scalability. A wrong choice can lead to the "let's rewrite from scratch" decision 2 years later.

At Novexing, we prefer the trio of Next.js, TypeScript, and Tailwind CSS. In this article, we explain why.

Why Next.js?

React Ecosystem

React has become the standard for component-based UI development. It offers a large community, rich library ecosystem, and proven production performance.

Next.js is a framework built on top of React. It provides ready-made features like routing, server-side rendering, and static generation.

Performance Options

Next.js offers three different rendering strategies:

SSG (Static Site Generation): Generates HTML at build time. The fastest option.
SSR (Server-Side Rendering): Renders on the server with each request. For dynamic content.
ISR (Incremental Static Regeneration): Refreshes static pages at set intervals.

You can choose a strategy on a per-page basis according to project needs.

App Router

The App Router introduced with Next.js 13+ allows you to manage features like layout systems, loading states, and error boundaries through the file system.

Why TypeScript?

Error Catching

JavaScript's biggest problem is errors that crash at runtime. TypeScript catches most of these errors while you're still writing code.

// JavaScript: Crashes at runtime
function greet(user) {
  return user.name.toUpperCase();
}
greet(null); // Cannot read property 'name' of null

// TypeScript: Warns at compile time
function greet(user: User | null) {
  return user?.name.toUpperCase(); // Safe
}

Documentation

Type definitions become the code's own documentation. You can understand what a function expects and returns from the types.

Refactoring Safety

When making major changes, TypeScript shows all affected locations. The "I changed one thing and something else broke" problem is minimized.

Why Tailwind CSS?

Utility-First Approach

Tailwind provides ready-made CSS classes. Each class does one thing:

<button class="bg-red-500 text-white px-4 py-2 rounded-lg hover:bg-red-600">
  Submit
</button>

Design System Compatibility

Tailwind's spacing, color, and typography scales create a consistent design system. p-4 gives the same padding everywhere.

Bundle Size

Unused classes are automatically removed from the production build. The final CSS file stays small.

Customization

You can define brand colors, fonts, and spacing values through tailwind.config.js.

Alternatives and Trade-offs

Vue/Nuxt

Vue offers an easier learning curve. However, the React ecosystem is broader and finding talent is easier.

Svelte/SvelteKit

Svelte, as a compile-time framework, promises smaller bundle sizes. It hasn't matured as much as React yet.

CSS-in-JS (Styled Components, Emotion)

There's the advantage of keeping CSS together with the component. However, there are runtime overhead and bundle size disadvantages.

Conclusion

Technology selection should be project-specific. However, for most web projects, the Next.js + TypeScript + Tailwind combination is a balanced choice.
