redux-loop is a JavaScript library that ports the Elm Architecture's effect system to Redux, letting reducers declaratively describe side effects via Cmd objects returned alongside state. Effects are only interpreted by an enhanced store, keeping reducers pure and easily testable.

Use cases

• handle async side effects in Redux reducers purely
• replace redux-thunk with declarative effect handling
• make Redux reducers fully testable with deep equality
• sequence and compose asynchronous effects like Elm
• migrate an existing redux-thunk codebase to redux-loop
• build action queues for ordered async requests

When to choose

• you use Redux and want Elm-style effect management from reducers
• you need deterministic, easily testable reducer behavior including effects
• you want all application behavior traceable through reducers

When to avoid

• you use Redux Toolkit or modern Redux patterns with RTK Query
• you prefer middleware-based async handling like redux-saga or redux-observable
• you are starting a new project without legacy Redux
