Architecture Overview

Frontend Architecture Overview - WIP

This section covers different architectural approaches and patterns for building scalable, maintainable frontend applications.

Architectural Patterns

Layered Architecture

Organize your code into well-defined layers with clear separation of concerns. Each layer has a specific responsibility, making your application easier to understand, test, and maintain.

Best for: Medium to large applications that need clear separation between UI, business logic, and data access.

Clean Architecture

Build applications with dependency inversion, where business rules are independent of frameworks, databases, and external agencies. The most flexible and testable architecture pattern.

Best for: Complex applications that need to be framework-agnostic and highly testable.

Choosing the Right Architecture

When selecting an architecture pattern, consider these factors:

• Team Size: Larger teams benefit from clear boundaries and separation of concerns
• Application Complexity: More complex applications need more structured approaches
• Scalability Requirements: Consider future growth and maintenance needs
• Development Speed: Some patterns require more upfront planning but pay off in the long run
• Team Experience: Choose patterns your team can understand and maintain

Common Principles

Regardless of the specific pattern you choose, these principles apply to all good frontend architecture:

• Separation of Concerns: Each module should have a single, well-defined responsibility
• Dependency Inversion: High-level modules should not depend on low-level modules
• Single Responsibility: Each class or function should have one reason to change
• Open/Closed Principle: Open for extension, closed for modification
• Testability: Architecture should make testing easy and comprehensive
