Learn everything about Flux architecture in react. The need for Flux architecture to Enhance the React performance in React.

1. What is Flux
architecture in React?

2. What is Flux architecture in React?
• Flux is an architecture that Facebook uses internally when operating
with React. So, in this article, we will see what is Flux architecture in
React.
• Flux is not a framework or a library. It is an architecture that enhances
React and also the idea of unidirectional data flow. Redux is a
predictable state container for JavaScript apps. Redux is a state-
management tool that we use in React. Now speaking in terms of
React, simple applications have some components. If you make any
changes in components it will reflect back to the main component.
After that, it modifies the state.

3. • But in reality, while creating a web application to solve a real-world
problem, we encounter hundreds of components that are organized
into multiple groups rather than one group with one main
component. So they are organized into multiple groups wherein each
group has a main component managing the state of that group.
• Now, if you make changes to one of the components then one of the
other components may need re-rendering but if they don’t share a
common main component then passing of information between them
can be difficult. This is where we need an MVC (Model, View,
Controller) model for the application.

4. Need for Flux Architecture:
• MVC faced certain issues due to which it couldn’t manage the
application the way we wanted it to. That’s where a new approach
called Flux architecture originated from the MVC model was
designed. This approach was basically designed to organize your code
in a simpler web. The problem that MVC encountered was the fact
that the updates, lead to a cascading flow of updates within the
models, and this becomes a tangled web, which makes the
application really complex.

5. • The flux architecture, however, provides a unidirectional flow where a
central unit for the entire application is called the store. In Flux
architecture, you can have multiple stores. A store basically acts as a
storehouse for the application state. So, you can only modify the state
of your application by requesting the store. The dispatcher becomes a
controlling unit for serializing any actions that are requested for
changing the store. The store can be subscribed by views, be it React
views or controller views.

6. • The storehouse of the state is the main component that will get its
state from the store of the flux architecture. Now whenever a change
is made, the controller views go back are able to get the updated
state.
And this, in turn, might result in the re-rendering of some parts of
your views or some parts of your components within your
application. So, this is what is meant by the unidirectional flow of
data which forms the basis for the Flux architecture.
