QUESTION
My approach below feels way to complicated for a simple thing I am trying to achive:
I have a list of Task
s that is managed by a TaskBloc
. The UI lists all tasks and provides an execute
button per task. For each click on that button I want to create and store an Action
(basically the timestamp when the task-execution happened) and show a spinner while the action is created. I have an ActionBloc
that manages the actions (e.g. creation or getting the history per task).
I am confused how to setup the communication between the BLoCs.
This is my approach so far.
The ActionsState
just holds a list of all stored actions.
ANSWER
Answered 2021-Mar-25 at 16:18So what we ended up doing is the following:
Introduce a lastCreatedState
in ActionsState
that represents the status of the last created action.
Instead of always listening to the ActionsBloc
all the time we listen to its state temporarily when task execution is happening and remember the listener per event.
Once we got a change in the ActionsBloc
lastCreatedState
state that indicates success or failure of our task we remove the listener and react to it.
Something along the lines of this:

QUESTION
I need to remove specific header (Date) from the Angular Universal SSR page, so that final HTML won't have this value in file. Considering that I cannot remove this header from API server response, is there any way to achieve this using Angular?
Here is the example of serverApp-state script tag, inserted on page, with that header:
...ANSWER
Answered 2021-Mar-09 at 09:27If you use the default TransferHttpCacheModule
, this module will register an interceptor that will cache xhr responses, including headers, in the transfer state (see interceptor's code)
So, if you do not want these headers, here are a few options
Option #1
you can write your own interceptor, based on the default one, but do not cache headers. Once this is done, you just need to provide your interceptor in your app module providers
QUESTION
I see there are lots of similar question in Javascript/React but I'm having this issue with CLojureScript/Reagent and I'm at a loss about how to solve it without messing up all my app-state names.
So I'm getting these warnings in the browser console:
...ANSWER
Answered 2021-Feb-12 at 15:05React really shouldn't be able to see your state or care what's in it. My guess would be that you are rendering your state somewhere in the props positions. Most likely somewhere in your code you have [:div @app-state]
. Possibly you were trying to render the state and should've done [:div {} @app-state]
.
This is perhaps a bit of a gotcha with Reagent, since [:p @im-a-string]
would render the string but [:p @im-a-map]
will treat the map as props.

I'm working with Angular and I'm trying to use Redux to implement JWT authentication and authorization in my project but the "Store.ts" throws an error that states the following:
...ANSWER
Answered 2021-Feb-06 at 13:52You need to provide a default state in reducer:

QUESTION
Following this question, I understand why StatefulWidgets do make sense in the context of a Redux-based flutter app. And that's what I'm trying to accomplish as well-
a Page that is "fed" information from the app-wide state (logged in user details, api data, etc) and can also dispatch actions from it's connected ViewModel, but one that ALSO contains stateful widgets with a smaller scope, short-lived state. things like Animation, validating user input on the fly before submitting, and changing the UI based on user actions.
So I'm interested in the how and hope someone here can help me. Currently all of my "pages" are stateless widgets connected to the app-state via the store, in the following manner:
...ANSWER
Answered 2021-Jan-24 at 13:19Here are some ideas that might help.
Your widget needs to be Stateful. You are trying to keep track of the color that will change over time. Stateless widgets only allow final properties - i.e. you can only initiate their value on creation.
Your variable isGreen and method changeColor() should be part of the state object. Your build() method will also go there.
Next - when you call your method you should call:

The Major scenario is I want to have a timer for getting new notifications, but sometimes I need to get notifications out of interval cycle that I have defined, so I put it in a useEffect wrapper, And I made a state in a customHook so I can change it from other components and I use that sate in my useEffect hook dependency list. Now I expect Compo1 to re run useEffect but it's not happening...
I have a project with this package.json:
...ANSWER
Answered 2021-Jan-06 at 13:09Each time you call your custom hook useHeaderNotifUpdater()
it will create a new state. You should create only one state on the common parent component or create a global state with a context or a management state lib.
