For example we have a feature reducer like this: // selectCard :: String -> Action String export const selectCard = createAction(SELECT_CARD) // showFeedback :: String -> Action String export const showFeedback = createAction(SHOW_FEEDBACK) // reduc…
Functions in Java Prior to the introduction of Lambda Expressions feature in version 8, Java had long been known as a purely object-oriented programming language. "Everything is an Object" is the philosophy deep in the language design. Objects a…
We have State like this: const state = { cards: [ { id: "green-square", color: "green", shape: "square" }, { id: "orange-square", color: "orange", shape: "square" }, { id: "blue-triangle&quo…
With a well defined demarcation point between Redux and our State ADT based model, hooking up to a Redux store is no different than any other Redux based implementation. Once we have all of our transitions represented in dispatchable actions, we can…
When combining multiple State ADT instances that depend on the same input, using chain can become quite burdensome. We end up having to play leapfrog with values inside of nested chain statements. Very reminiscent of the old callback nastiness we had…
With our Redux implementation lousy with State ADT based reducers, it is time to hook it all up to a React Shell. Having already built out some UI/UX in React that is connected to our store, we’ll spend the first part of this lesson with a quick tour…
Not only will we need to give our initial state to a Redux store, we will also need to be able to reset our state at any time by dispatching an action. We can get the best of both worlds by having a function that will return an object with all of our…
Redux provides a convenient helper for combining many reducers called combineReducer, but it focuses in on specific attributes on our state, making it incompatible with using the State ADT. We would like a way to avoid keeping all of our reducers in…
The typical Redux Reducer is function that takes in the previous state and an action and uses a switch case to determine how to transition the provided State. We can take advantage of the Action Names being Strings and replace the typical switch case…
By using the State ADT to define how our application state transitions over time, we clear up the need for a some of the boilerplate that we typically need for a solid Redux integration. We can keep our action names and creators in the same file as t…
