Why is thunk used?
Redux Thunk is a middleware that lets you call action creators that return a function instead of an action object. That function receives the store’s dispatch method, which is then used to dispatch regular synchronous actions inside the function’s body once the asynchronous operations have been completed.
What the heck is a thunk?
If you want an action to do something, that code needs to live inside a function. That function (the “thunk”) is a bundle of work to be done. … Update: As rixman mentions in the comments, the getState function can be useful for deciding whether to fetch new data, or return a cached result, depending on the current state.

Is Redux needed?
Your application might still work well without Redux. One major benefit of Redux is to add direction to decouple “what happened” from “how things change.” However, you should only implement Redux if you determine your project needs a state management tool.

What is Redux used for?
Redux is used mostly for application state management. To summarize it, Redux maintains the state of an entire application in a single immutable state tree (object), which can’t be changed directly. When something changes, a new object is created (using actions and reducers).
Is Redux server side?
On the client side, a new Redux store will be created and initialized with the state provided from the server. Redux’s only job on the server side is to provide the initial state of our app.
What is a thunk function?
Thunk is a function that wraps another function or expression to delay computation. Thunk can also be used to add additional calculations to a function. Thunks provide lazy evaluation and are widely used in functional programming languages.
Who would’ve thunk?

Is Redux difficult?
Yes, in some ways Redux is more complicated. It adds a couple levels of indirection to the process of updating state, there’s a bunch of new terms, and it requires thinking about your code in some ways that are probably very new and different for you. So yes, many people do find it confusing to start with.
What is redux pattern in angular?
Redux is a reactive state management library developed by Facebook and used in the React library. This library is based on the Flux pattern. … This is a reactive state management library. With NgRx, we can get all events (data) from the Angular app and put them all in the same place (Store).
Are Redux actions async?
2 Answers. AFAIK, dispatching action is synchronous. In case if you are willing to address the asynchronous call, you can use the thunk-middleware in redux, where dispatch is provided as a callback function which you can invoke as per your convenience.
What is the difference between Redux thunk and Redux saga?
The idea is that a saga is similar to a separate thread in your application that’s solely responsible for side effects. However, unlike Redux-Thunk, which utilizes callback functions, a Redux-Saga thread can be started, paused and cancelled from the main application with normal Redux actions.
