Understanding business logic leaks
Business logic refers to the rules, calculations, and processes that are essential to the operation of a business application. When this business logic “leaks” into components or areas of the application where it doesn’t belong, this is known as a business logic leak.
This issue frequently crops up in various projects, partly because there’s no widely agreed-upon approach for handling business logic in React. The framework’s flexibility allows you to implement this logic directly in components, Hooks, or helper functions; as a result, developers often end up embedding the logic directly into components, where it’s immediately needed – hence the leakage.
This leakage can cause many problems. Business logic leaks can result in tightly coupled components that become difficult to test, maintain, or reuse. When business logic is scattered across different parts of the application, it leads to code...
