MVC vs. Flux vs. Redux: What Should You Pick?

Introduction

The Importance of Making the Right Architecture Decision
That is why in the world of web development the architecture one decides to implement can either become the project’s making or breaking point. It affects the level of difficulty in maintenance and the expansion of your application. Therefore, one should employ good judgment when it comes to the decision between MVC, Flux and Reds.

Understanding MVC

What is MVC?

MVC stands for Model-View-Controller. It’s a design pattern that separates an application into three main logical components: those are the model view and the controller. Every part has its functionality, which contributes to the fact that the development process is less overwhelming.

How MVC Works

The first component of MVC is the Model; it captures the data and the application’s business logic. The View is concerned with presenting the data to the client. The Controller relates with the user and processes his/her input before transmitting the result to the Model and View.

Advantages of using MVC and the Disadvantages of using MVC

Pros:

Certainly, the division of concerns lead to manageable and testing of the application becoming easier.
Reusability of components.
Improved organization of code.

Cons:

May get rather complicated with the growth of the application.
Can at times led to a form of tight coupling within the system’s components.

Diving into Flux

What is Flux?

Flux is application architecture employed by Facebook in development of client-side web application. It also uses a unidirectional data flow which enriches React’s component model.

How Flux Works

Flux architecture comprises four main parts: Virtually all the components in the application are accounted for in the above-mentioned associational acronyms of MVC, namely Actions, Dispatcher, Stores, and Views. Activities are messages of information that transfer data from the application to the Dispatcher. All these actions are then forwarded to the Stores by the Dispatcher, who contain the application state and logic. Last, but not the least, the Views (React components) get updated depending on the state transition in the Stores.

Advantages / Disadvantages of Flux

Pros:

It makes it easier to debug the application as well as to understand as it only flows down in one direction.
Simplifies state management.

Cons:

May be excessive for small applications, especially when a template is created to accommodate for all of the record types associated with a specific project.
This depends on the architecture hence needs one to have a good understanding of the architecture.

Exploring Redux

What is Redux?

Redux is a predictable state container for JavaScript apps. Conversely, it works exceptionally well with React but can be employed with almost any other view library/framework.

How Redux Works

Redux operates on three core principles: Single Source of Truth, State is Read Only while the Changes are Descrites by Pure Functions. Actions, Reducers and a Store. The Store is responsible of preserving the application’s state. Reducers describe how the state transforms working with Action.

Advantages and Disadvantages of Redux

Pros:

Predictable state management.
The centralized state helps a lot in debugging and testing.
Suits the type of large business applications where the changes in the business environment can be easily identified.

Cons:

It can be clearly stated that boilerplate code may be overwhelming.
Slopes very high for anyone who is new to it.

Comparative Analysis

MVC vs. Flux

Thus, MVC and Flux are the tools that relate to each other in terms of their functions rather than being interchangeable. MVC is a design pattern that spells out separation of concerns while Flux is an architecture that tries to manage action and state. Flux can deal with sophisticated UIs compared to MVC that can face difficulties with such forms of bi-directional data changes.

MVC vs. Redux

Redux is described to be more predictable in nature compared to MVC for state management. As MVC overly decomposed the parts, Redux unifies them in one store, thus it is easier to comprehend and control an application of any complexity.

Flux vs. Redux

Flux an Redux implement unidirectional data flow but the latter further streamlines the process in terms of not requiring Dispatcher, only using pure functions (Reducers). Redux also includes the concept of middleware to improve its effectiveness in dealing with such undesired effects as well as asynchronous operations.

Choosing the Right Architecture

Factors to Consider

When choosing between MVC, Flux, and Redux, consider the following factors:When choosing between MVC, Flux, and Redux, consider the following factors:

Project Size and Complexity: MVC could be enough for simpler applications and Flux/Redux are more suitable for large scale applications.
Team Expertise: Select an architecture that students feel familiar or at ease to work with.
State Management Needs: If the state’s top priority is expected and centralized control, Redux is commonly the most indicated.

Use Cases for MVC

MVC is ideal for:

Usability of applications and particularly simple or moderately complex ones.
Situations in which it is favorable to divide the concerns of a project.
Teams of designers who are already capable of constructing models according to the styles of the regular world.

Use Cases for Flux

Flux is suitable for:

Applications built with React.
Situations where the sender of data wants the receiver to be restricted in the response that he/she can provide.
Because PHP is easy to understand and commonly used, developers surrounded the architecture of Facebook.

Use Cases for Redux

Redux shines in:

Large-scale applications.
Projects which require manageable states and those which require exact state definition.
When the required solution development teams are familiar with functional programming concepts.

Conclusion

Selecting the right architecture for your project is very important. Some of the pros and cons of MVC, Flux, and Redux make it possible to determine that the best solution depends on the tasks at hand. Studying these architectures will help you to make right decision, which will contribute to success of your project.

FAQs

What is MVC?
MVC stands for Model-View-Controller, a design pattern that separates an application into three main components: The three fundamental components that make up the architecture of any Ruby on Rails application are, the model, the view, and the controller.

What are the changes that have been made to support Flux over MVC?
While working, Flux employs the unidirectional flow of data, which makes the state control rather clear and effortless; at the same time, MVC presupposes the bidirectional flow of data, which may become rather complicated in the case of large-scaled applications.

I have been using a simple state container without redux and it works fine, so why do I need redux?
Redux introduced a clear USP that the application state is managed at one place and debugging as well as testing gets easier.

Is Redux equally applicable to frameworks other than the React?
Yes, Redux can be used with any view library or framework and you do not have to use the React library.

Which architecture is recommended for a small project?
Decidedly, for small works, MVC is enough since the implementation of the model is simplified.
