Write S.O.L.I.D code

Learn how to write Object Oriented S.O.L.I.D code

1. @yot88 By yoan thirion S.O.L.I.D principles
2. @yot88 bad code / Good code Bad code vs Good code Categorize each piece of code
4. @yot88 Singleton Tight Coupling Untestability Premature Optimization Indescriptive Naming Duplication Single Responsibility Open/Closed Principle Liskov Substitution Interface Segregation Dependency Inversion Patterns and anti-patterns
5. @yot88 SRP A class should have only 1 responsibility
6. @yot88 Software entities should be open for extension, but closed for modification. Open closed
7. @yot88 Subtypes must be substitutable for their base types. Liskov substitution
8. @yot88 Clients should not be forced to depend on methods that they do not use. Interface segregation
9. @yot88 High level modules should not depend on low level modules : both should depend on abstractions. DI
10. @yot88 Good code / bad code Align each piece of code with a S.O.L.I.D principle

20. @yot88 Let’s refactor using s.O.L.I.D
21. @yot88 exercises Practice S.O.L.I.D principles on code examples Clone the repository at : https://github.com/ythirion/solid-kata Foreach code example : • identify why it’s breaking the given principle • Write down your refactoring strategy • Refactor it
