dev(refactor): Design pattern

[Cyber-Syntax]

What is the exact problem?

I am frustrated to update classes over and over again for the new features or fixes.

Which design pattern would be better?

Cretional design patterns

• Abstract Factory
• Factory
  • We already uses this on some part of classes.
• Builder
• Singleton
• Prototype

Structural design patterns

• Adapter
• Bridge
• Composite
• Decorator
• Facade
  • We already uses this on some part of classes.
• Flyweight
• Proxy

Behavioral design patterns

• Chain of responsibility
• Command design pattern
  • It is good for cli.
• Iterator
• Mediator
• Memento
• Observer
  • It would be useful for the updates notification?
• State
• Strategy
  • It would be great for verification strategies.
• Template
• Visitor

Is it overkill to use design pattern?

I am not trying to fit design pattern to my project, I am trying to solve the problem I encounter.
Therefore, I don't think it is overkill but it might be solution.
