MVC vs Flux vs Redux – What’s The Differences?

MVC vs Flux vs Redux

While developing web applications, we create solutions that address the customers’ needs and solve issues of organizations and users. To accomplish this, various architecture patterns and technologies are used. For a long time, application designs have revolved around the MVC (Model-View-Controller) pattern. Meanwhile, there have been a series of advanced frameworks like Flux and Redux, in a similar vein, which helps you to manage complex applications. We know about the complexity in applications that increases because of the effective design patterns in place. Here we have compared MVC vs Flux vs Redux to help you make effective, sensible and scalable application architecture.

Comparing MVC vs Flux vs Redux-

1. Architecture-

MVC Architecture-

MVC Architecture

MVC is popular for its three-layer development architecture and it separates applications into three components:

  • Model: Maintains the data and behavior of an application
  • View: Displays the model in the UI
  • Controller: Serves as an interface between view & model components

When the controller gets the request from the user, it uses the proper Model and View and generates the response sending it back to the user.

Flux Architecture-

After learning a few features with respect to the instability and complexity of the MVC architecture, the Facebook development team rolled out some significant improvements in the system and released Flux as an alternative to MVC architecture. The Flux architecture is based on the accompanying components:

  • Store/ Stores: Serves as a container for the app state & logic
  • Action: Enables data passing to the dispatcher
  • View: Same as the view in MVC architecture, but in the context of React components
  • Dispatcher – Coordinates actions & updates to stores

In the Flux architecture, when a user clicks on something, the view creates actions. Action can create new data and send it to the dispatcher. The dispatcher then dispatches the action result to the proper store. The store updates the state according to the result and sends an update to the view.

Redux Architecture-

Redux is a library, which implements Flux however in a different manner. It introduce new components like:

  • Reducer: Logic that determines how your data changes exist in pure functions 
  • Centralized store: Holds a state object that indicates the state of the whole application

In Redux architecture, application event is signified as an Action, which is dispatched to the reducer, the pure function. Then reducer updates the centralized store with new data according to the type of action it receives. Store makes another state and sends an update to view. At this time, the view was recreated to reflect the update.

2. Data Flow Direction-

MVC-type implementation upholds bidirectional data flows, which varies from the unidirectional data flow maintained in Flux and Redux. In MVC, there is no single direction in an application that data flows in. Here, various parts of the system have the authority to change state and state is decentralized all through the application. For example, consider a large application where you have a collection of models including the user, authentication, account, and so on., and they are packaged with their own controllers and views. Here, it is hard to track the specific location of a state since it is distributed over the application.

Flux and Redux don’t encourage bi-directional flow to ensure clean data flow architecture. The huge advantage of a unidirectional approach is that since the data flows through your application a single way you can have better control over it.

3. Single or Multiple Stores-

Flux uses ‘Stores’ to cache any application related with data or state whereas MVC model attempts to model a single object. MVC doesn’t have the concept of the Store. The Store is similar to a model in MVC, but it handles the state of a few objects rather than simply signifying a single database record. The main difference of Flux vs Redux is that Flux incorporates different Stores per application, but Redux incorporates a single Store for each application. Instead of placing state data in various Stores across the application, Redux keeps everything in one region of the application.

Why is Redux upholding a single global store, you wonder? Consider your action uses numerous stores; there is a scope of forgetting to deal with the action in specific stores. This causes an issue in application management. Also, it is difficult to get an outline of what your state includes. Updates are another issue with numerous stores in Flux. These issues lead you to what a single centralized store in Redux offers. All the changes in Redux are made through a pure function called Reducers.

4. Where Business Logic resides?

In the computer application, domain logic or business logic is that part of the program which translates real-time business rules into how data can be created, stored, displayed as well as changed. In MVC, the controller takes the responsibility of dealing with the data and state of the application. It is responsible for the initial processing of the request, but business decisions should be done within the model. Similarly, it is interesting to comprehend the business logic dealing with Flux vs Redux. In Flux, the logic of changes in the data based upon the actions is mentioned in its appropriate Store. The Store in the Flux application possesses the flexibility to choose what parts of your data to show publicly. In Redux, then again, the logic remains in the reducer function, which gets the previous state and one action, then returns the new state.

5. How Debugging is handled?

The bidirectional data flow between view and models makes it difficult to debug with MVC applications. On the other hand, the Flux architecture is especially useful for actions that include side effects like making the code more clear, updating other views and debug by new developers. Flux incorporates singleton dispatcher and all actions are going through that dispatcher. This design defends hard-to-debug cascading updates.

Redux doesn’t have a dispatcher. You may be confused about how Redux handles debugging, right? In Redux, it is significantly simpler to oversee data and debug because the state of your whole application is maintained inside a single Store. Moreover, the state of all components relies upon one object tree.

It is conceivable to log all the actions that have been performed to find a certain point. This enables you to look at the application as a whole and debug easily. Over this, it offers a great Live Code-Editing alternative with a time-traveling debugging feature. This feature allows you to rewind and replay your debugging action.

6. Where can be used?

MVC is well known in both server-side and client-side frameworks. There is no deficiency of front-end frameworks, which can support you to interface with MVC. AngularJS, Ember, Backbone, Sprout, and Knockout are some examples. The MVC also shines on the backend frameworks or solutions like Spring, Ruby on Rails, Django, Meteor, and so on. Flux and Redux, are generally a front-end pattern. Flux tends to the issues of handling the application state on the client-side. Thus, the front-end frameworks and libraries like Angular 2, Vue.js, and Polymer would all be able to have a natural interaction with Flux.

When comparing the usability of Flux vs Redux, both score the equivalent. But, Redux isn’t only a state management library, it offers a few advantages for your front-end applications, including ensuring data consistency, sharing data among components and giving templates for code organization. Redux is basically associated with React, but it can function well with different libraries also, including Vue.js, AngularJS, Ember, Backbone.js, Meteor, and Polymer.

Wrap up-

These are some powerful design patterns to make your apps UI attractive and usable. Consider these comparisons between MVC vs Flux vs Redux, and decide which is appropriate for your business. It depends on the technologies you use and the goal of your application.
