Interface Middleware<DispatchExt, S, D>

Callable

• Middleware(api: MiddlewareAPI<D, S>): ((next: Dispatch<AnyAction>) => ((action: any) => any))

• A middleware is a higher-order function that composes a dispatch function to return a new dispatch function. It often turns async actions into actions.

  Middleware is composable using function composition. It is useful for logging actions, performing side effects like routing, or turning an asynchronous API call into a series of synchronous actions.

  Parameters

  • api: MiddlewareAPI<D, S>

  Returns ((next: Dispatch<AnyAction>) => ((action: any) => any))

  • • (next: Dispatch<AnyAction>): ((action: any) => any)

    • Parameters

      • next: Dispatch<AnyAction>

      Returns ((action: any) => any)

      • • (action: any): any

        • Parameters

          • action: any

          Returns any
