If you are java developer and you are not good at design and frontend skill but you want to develop a java web application using microservices style, Angular is the best choice as front-end framework for you. Angular is like java Wicket framework. Both use real html DOM in markup file so that It is easy to incorporate with cut-css/html frontend developer to make a target ui page.
Redux is a predictable state container for JavaScript apps and Redux was designed for React.
There are several ways to use Redux or create a Redux-inspired system that works with Angular. We can use Redux directly in order to show the concepts without introducing a new dependency (pure redux). But Angular also has state container by supporting from popular state management frameworks: angular-redux, ngrx, ngxs, akita
According to the link https://www.npmtrends.com/@angular-redux/store-vs-@ngrx/store-vs-@ngxs/store we can see that NGRX is most downloaded among Angular's state management framework.
Pure redux with Angular: example https://github.com/ng-book/angular2-redux-chat/tree/master/redux-counter
NGXS’s .state = NGRX’s .effects + .reducers + .selectors. NGXS has an OOP approach and it is less boilerplate than NGRX but is is still boilerplate.
NGRX is a Redux-inspired architecture and it has Angular's Lifestyle in building a state management framework that is heavily observables-based. It has high downloaded volume. It is difficult to adapt due to high boilerplate in the past but NGRX is improved now.
angular-redux uses Redux itself as a dependency, and adds some Angular helpers, but It is not continue to update. The architecture of angular-redux is clear, it is the same as the pure Redux library, the building-a-food-store-using-redux-and-angular is a good example.
AKITA: is new to community. Akita is built on top of RxJS, which takes the idea of multiple data stores from Flux and the immutable updates from Redux, along with the concept of streaming data, to create the Observable Data Store model.
By adding Redux-inspired architecture into Angular, now Angular developer will understand redux framework that are used mainly in reactjs|react-native.
In general, NgRx architecture is so same as Redux, how ever EFFECTS in NgRx has a part feature of middleware and a part not yet.
We can see the image of Redux from https://medium.com/@lavitr01051977/basic-react-redux-app-with-async-call-to-api-e478e6e0c48b
Other feature of NgRx in comparing to Redux is that NgRx use much
NGXS - https://www.ngxs.io/
NGXS is a state management pattern + library for Angular. It is the same as NGRX but It reduces boilerplate by using modern TypeScript features such as classes and decorators.

@ngrx/store
Store is RxJS powered state management for Angular applications, inspired by Redux. Store is a controlled state container designed to help write performant, consistent applications on top of Angular.- Actions describe unique events that are dispatched from components and services.
- State changes are handled by pure functions called reducers that take the current state and the latest action to compute a new state.
- Selectors are pure functions used to select, derive and compose pieces of state.
- State is accessed with the
Store, an observable of state and an observer of actions.
In general, NgRx architecture is so same as Redux, how ever EFFECTS in NgRx has a part feature of middleware and a part not yet.

select operator to select data from the state.NGXS - https://www.ngxs.io/
NGXS is a state management pattern + library for Angular. It is the same as NGRX but It reduces boilerplate by using modern TypeScript features such as classes and decorators.
There are 4 major concepts to NGXS:
- Store: Global state container, action dispatcher and selector
- Actions: Class describing the action to take and its associated metadata
- State: Class definition of the state
- Selects: State slice selectors
These concepts create a circular control flow traveling from a component dispatching an action, to a store reacting to the action, back to the component through a state select.
As the result, NGRX or AKITA or NGXS will be a good choice for State management in Angular. Although I like angular-redux but it is not continue by contributors. AKITA is multi store so that it breaks the architecture of Redux. NGRx has learned from AKITA the concept EntityState and it also keeps Redux way in coding. If you use NgRx It will help you to understand more about Redux.
