strategy-pattern

To replace switch or if/else chains with swappable algorithms, define a common strategy interface, implement multiple concrete strategy classes, and select the desired algorithm at runtime. This refactoring encapsulates behavior, making it pluggable without modifying existing code.

The strategy pattern encapsulates a family of interchangeable algorithms behind a common interface. Use it for runtime behavior selection when you need to swap logic dynamically, such as changing export formats, pricing strategies, or compression selection without altering client code.

Yes, the strategy pattern works with both TypeScript and Rust. In TypeScript, you can use function-based or class-based strategies implementing a shared interface. In Rust, you define a strategy trait and implement it for multiple concrete structs to achieve runtime algorithm selection.

Implement a strategy registry in Rust by defining a trait for your algorithms, creating concrete implementations, and storing them in a collection like a HashMap. You then select and execute the desired strategy at runtime by looking up the appropriate trait object.

Use the strategy pattern instead of conditional logic for authentication modes to make behavior pluggable and extensible. It encapsulates each authentication algorithm behind a common interface, allowing you to register or select modes at runtime without expanding a switch statement.

Yes, you can use function-based strategies in TypeScript. The strategy pattern supports both function-based and class-based approaches, allowing you to define interchangeable algorithms as typed functions that conform to a shared signature for runtime selection.
