πŸ“„ Angular’s GoF patterns. Factory Method.

#angular #patterns

Advantages:

β€” Flexibility and expandability: Allows for easy introduction of new types of products without changing existing code.
β€” Reducing dependencies: The Factory Method reduces the direct dependency between classes that create and use objects, making code modification and testing simpler.
β€” Ease of maintenance and updates: Code using the pattern is easier to maintain and update, as adding a new type of product often doesn’t require changes to the existing code that uses the factory.


Disadvantages:

β€” Complex architecture: Using Factory Method can complicate application architecture, especially when used unnecessarily or in simple scenarios.
β€” Code bloat: Creating many factory methods and classes can overload the code, making it hard to understand, particularly for new developers.
β€” Performance issues: In some cases, particularly with incorrect implementation, Factory Method can affect application performance due to additional method calls and object creations.
β€” Debugging difficulty: Following this pattern can make debugging harder since the actual object creation is hidden within the factory method, complicating error tracking.
β€” Need for careful planning: Effective use of Factory Method requires detailed planning and understanding of when and what objects should be created. Planning errors can lead to incorrect or excessive implementation.
β€” Limited flexibility in some scenarios: While Factory Method provides flexibility in object creation, it can be limited in scenarios requiring very dynamic or conditional object creation.
β€” Not suitable for simple applications: For small or simple applications with a relatively static structure, using Factory Method might be unnecessary and complicate the project.

Hello, friends!
As you can see, I'm a Ukrainian software engineer who tries to do volunteer fundraisers to support the Armed Forces of Ukraine.

Thank you very much!
