Redux‑Saga is a Redux middleware that uses ES6 generator functions to manage side effects such as data fetching, caching, and more. It provides a declarative, testable approach to asynchronous flows in JavaScript applications.

Use cases

• handle asynchronous data fetching in a React‑Redux application
• manage complex side‑effect workflows like cancellation, debouncing, and throttling
• coordinate multiple concurrent or sequential tasks in a Redux store
• write testable side‑effect logic using generator functions
• integrate with existing Redux codebases without changing action creators

When to choose

• You need fine‑grained control over async flows, including cancellation and concurrency.
• Your project already uses Redux and you want a scalable side‑effect solution.
• Testing side effects is a priority and you prefer a declarative, generator‑based API.

When to avoid

• Your app only has simple async calls; Redux‑Thunk or plain async/await would be simpler.
• You want to avoid adding another abstraction layer or learning generator syntax.
• Performance-critical code where the overhead of middleware is a concern.
