🚀 How to Organize Your Web App. Part 2.

In the last post, we explored Layered Architecture - a simple and familiar way to organize code by technical roles (components, services, models).

But as your app grows, you'll quickly realize that layering alone doesn't scale well. What happens when features get complex, teams grow, or business rules evolve fast?

👉 That’s where Feature-Based Architecture and Domain-Driven Design (DDD) come in.

In this post, I’ll walk you through:

• What each pattern looks like in practice (especially in Angular)
• Their strengths and tradeoffs
• And how to choose the right one for your project stage

Let’s dive into two of the most scalable architecture patterns in modern frontend development. 🚀

🧩 Feature-Based Architecture

Group your code by features, not technical types. Like /auth, /profile, /orders, each with its own components, services, models, and routing.

Instead of:

You do:

Each feature folder contains everything it needs: components, services, routing, models, etc.

✅ Pros:

• Easy to scale horizontally - just add new feature folders.
• Keeps related code in one place → faster dev, better readability.
• Team-friendly: each squad can own a feature folder.
• Aligns well with Angular’s modular design (feature.module.ts + routing).

⚠️ Cons:

• Can lead to some duplication across features.
• Needs discipline in what’s “shared” vs “feature-specific”.
• Harder to reuse deeply nested logic if everything is siloed.

🛠️ Real Angular Example:

🔍 3. Domain-Driven Design (DDD)

💡 Core Idea:

Organize the app based on business domains, each one containing:

• Domain logic (core rules)
• Application logic (use cases)
• Infrastructure (APIs, DB)
• UI (components, pages)

DDD separates what your app does from how it does it.

✅ Pros:

• Ideal for complex, enterprise systems.
• Highly maintainable and testable.
• Encourages deeper modeling of business rules.
• Helps avoid the "big ball of mud" as your app grows.

⚠️ Cons:

• Overkill for small to mid-size apps.
• Steeper learning curve.
• More upfront design needed.
• Higher verbosity (more files per concept).
