Practice design patterns using Laravel examples

• Adapter
• Strategy
• Factory pattern combined with both

Adapter Pattern

• Integrating 3rd party APIs
• Depedency Inversion
• Use the container to swap implementations

Benefits

• Inverts dependency
• Ability to swap out implementations
• Easy to test

Strategy Pattern

• Clean up branching logic in large cases
• In-depth refactoring

Benefits

• Simplifies containing classes by removing conditional logic
• Allows to defer decisions until runtime
• Makes the clauses using the strategies "pluggable"

Factory Pattern

• Identify factories hidding in code
• Extact class refactor
• Take advantaje of Auto-wiring Service Container

Primmer

• Only responsible for creating objects of a specific type
• Encapsulate decision process for choosing the appropriate concretion

Benefits

• Moves creation logic out of dependant classes
• Simple and composable
• Lean on the Service Container to construct and inject
