  • Another issue we have encountered is that async actions, nearly in a 90% of cases dispatched a SUCCESS or a FAILURE action.
  • We can reduce this code: – To this: – completeReducer is a function that takes a reducer description and extends SUCCESS and FAILURE cases for all primary actions.
  • Since writing state fields from SUCCESS and FAILURE cases also might be a bit annoying, completeState adds loading and error for us: – And for action names, adding SUCCESS and FAILURE actions: – These completers take another param for the exceptions casesthose items that we dont want to extend.
  • In most cases, we write async actions to fetch things from a service and put them in the stores state.
  • We can write async actions as: – Those are conceptually the same as the first ones: they put loading flag in true, and according to the service response, dispatch a SUCCESS or a FAILURE action.

  • The callback will contain a and a object: – – Finally call the method and run your Node app: – – Sends data to the client.
  • Depending on the type of the passed object, it will send the data in one or multiple frames: – – Sends a ping frame that may contain a payload.
  • The client must send a Pong frame with the same payload in response.
  • You can then add listeners to the stream: – – Emitted when the server received a Ping frame from the client.
  • Emitted when the server received a Pong frame from the client.
