Singleton Pattern vs Service Locator Pattern
Developers should use the Singleton Pattern when they need to guarantee that only one instance of a class exists throughout the application's lifecycle, such as for managing a shared resource like a cache, thread pool, or settings manager meets developers should learn the service locator pattern when building applications that require loose coupling and centralized dependency management, such as in large enterprise systems or frameworks with complex service hierarchies. Here's our take.
Singleton Pattern
Developers should use the Singleton Pattern when they need to guarantee that only one instance of a class exists throughout the application's lifecycle, such as for managing a shared resource like a cache, thread pool, or settings manager
Singleton Pattern
Nice PickDevelopers should use the Singleton Pattern when they need to guarantee that only one instance of a class exists throughout the application's lifecycle, such as for managing a shared resource like a cache, thread pool, or settings manager
Pros
- +It is particularly useful in scenarios where multiple instances could lead to data inconsistency, high memory usage, or performance issues, such as in logging frameworks or global configuration objects
- +Related to: design-patterns, object-oriented-programming
Cons
- -Specific tradeoffs depend on your use case
Service Locator Pattern
Developers should learn the Service Locator Pattern when building applications that require loose coupling and centralized dependency management, such as in large enterprise systems or frameworks with complex service hierarchies
Pros
- +It is particularly useful in scenarios where services need to be dynamically resolved at runtime, like in plugin-based architectures or when implementing inversion of control
- +Related to: dependency-injection, inversion-of-control
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Singleton Pattern if: You want it is particularly useful in scenarios where multiple instances could lead to data inconsistency, high memory usage, or performance issues, such as in logging frameworks or global configuration objects and can live with specific tradeoffs depend on your use case.
Use Service Locator Pattern if: You prioritize it is particularly useful in scenarios where services need to be dynamically resolved at runtime, like in plugin-based architectures or when implementing inversion of control over what Singleton Pattern offers.
