BlockMiddleware

public final class BlockMiddleware: Middleware

Create a middleware inline with a block.

Example

let middleware = BlockMiddleware { action, getState, dispatch, next in
  // Read the state before any reducer changes it
  print("The old state is \(getState())")

  // Print the action
  print("The action is \(action)")

  // Continue the dispatching process..until the reducer reduces the action
  // Not calling `next` will prevent the action from reaching the reducer
  next?(action)

  // Read the state after any reducer changes it
  print("The new state is \(api?.state)")
}

  • Create a middleware with an onAction callback block
