laravel-strategy-pattern

To switch runtime behavior in Laravel without modifying client code, you define a common interface, create multiple concrete strategies, and use a factory or provider to resolve the desired implementation by key. This isolates client code from behavior changes.

The strategy pattern in Laravel is used for selecting interchangeable behaviors dynamically. It allows your application to choose a specific implementation, such as a country-specific tax calculation, based on runtime context or input keys without altering dependent code.

You implement a Laravel factory to resolve strategies by defining a common interface for the behaviors, creating multiple concrete implementations, and registering them in a provider. The factory then resolves the correct strategy by a contextual key.

Yes, the Laravel strategy pattern relies on dependency injection to switch implementations. You resolve the appropriate strategy implementation dynamically and inject it into the dependent code, ensuring the client receives the correct runtime behavior.

Use the strategy pattern in Laravel instead of hardcoding conditional logic when you need pluggable, interchangeable behaviors. It is ideal when you must select varying behaviors for different contexts or inputs at runtime while keeping the client code untouched.
