What is Redux?

Redux is a state management library for javascript applications, often used in conjunction with React. It Provides a predictable and centraloized way to manage and update the state of an Application.

• Actions:

Actions are plain JavaScript objects that represent events that occur in your application.They are the only source of information for the store and carry a type field to describe the type of action being performed. Actions are typically dispatched using store.dispatch(action).

• Reducers:

Reducers are functions that specify how the application's state changes in response to actions. They take the current state and an action as arguments and return the new state based on the action type. Reducers are pure functions, meaning they do not modify the state directly but return a new state object.

• Store:

The central part of Redux is the store, which holds the state of your application. It is a JavaScript object that contains the entire state tree of your application. You can access the state via the store and update it using reducers.

• View:

In Redux, the view architecture refers to how components interact with the Redux store to access and update the application state

Other Some Tools & Architecture of Redux:

Immutable State: Redux encourages immutability, meaning that state is never modified directly. Instead, new copies of state objects are created when changes occur. This helps in maintaining a predictable state flow and makes debugging easier.

Redux Benefits:

• Predictable State Changes:

With Redux's strict unidirectional data flow, state changes become predictable and easier to trace.

• Scalability:

Redux scales well with large applications, thanks to its structured approach to state management.

• Time Travel Debugging:

Redux enables time-travel debugging, allowing developers to replay actions and inspect state changes.

• Debugging is easy in Redux:

Redux makes it easy to debug an application. By logging actions and state, it is easy to understand coding errors, network errors, and other forms of bugs that might come up during production. Besides logging, it has great DevTools that allow you to time travel actions, persist actions on page refresh, and more.For medium- and large-scale apps, debugging takes more time then actually developing features. Redux DevTools makes it easy to take advantage of all Redux has to offer.

The Redux Workflow:

Understanding the Redux workflow involves recognizing the flow of actions through the system and how reducers respond to those actions.

• Action Dispatch:

Developers initiate state changes by dispatching actions using action creators.

• Reducer Execution:

Reducers specify how the state should change based on the action type.

• New State Creation:

Reducers create a new state object without modifying the existing state.

• Store Update:

The store receives the new state and updates its internal state accordingly.

• View Re-render:

Connected components re-render based on the updated state.

Conclusion:

Understanding the fundamentals of Redux — State, Actions, and Reducers — lays the groundwork for effective state management in your applications. By adopting a centralized store, predictable actions, and pure reducers, developers can maintain a clear and maintainable architecture. Additionally, the use of middleware extends Redux’s capabilities, enabling the handling of asynchronous operations and other side effects.
