YAGNI

YAGNI (You Aren’t Gonna Need It) is a software development principle that encourages developers to implement only what is necessary now, avoiding premature optimizations or unnecessary features. In Laravel and PHP development, this means focusing on writing clean, maintainable, and efficient code without overengineering.

Why YAGNI Implementation Needed

• Any work only used for a feature that will be needed tomorrow means wasting effort on features that need to be completed for the current iteration.

• It leads to code bloat; the software becomes larger and more complicated.

• Always implement things when you need them, never when you just foresee that you need them.

1. Avoid Premature Features

• Don't build extra features unless required.

• Do implement only what is currently needed for the project.

2. Use Simple Database Queries

• Don't create complex joins or eager-loaded relationships when they aren't needed.

• Do optimize queries based on actual use cases.

3. Avoid Over-Abstracting Code

• Don't create multiple layers of abstraction unless needed.

• Do use interfaces and services only when they provide a clear benefit.

4. Don't Overuse Configurations & Options

• Don't add too many environment variables or configuration options unless required.

• Do use sensible defaults.

5. Write Tests for Existing Code, Not Future Code

• Don't write tests for features that don’t exist yet.

• Do test only what has been implemented.
