### Component-Based Architecture

React adopts a component-driven architecture, encouraging the decomposition of your user interface into reusable, standalone components. This method fosters code reuse and simplifies the management of complex user interfaces.

This component architecture maximizes modularity. Developers can move relatively independently, assembling an application UI from discrete components. Related helpers like React Context provide dependency injection to streamline passing data between components.

Components are often organized into container and presentational types. Container components handle data and orchestrate child components. Presentational components focus solely on UI. This separation of concerns keeps components clean and reusable across contexts.

React’s component model builds UIs through composition, abstraction, and separation of concerns. Sufficient for simple apps, additional patterns build on this foundation to manage complexity.

### Model-View-Controller (MVC)

The Model-View-Controller (MVC) architectural pattern provides a well-structured application development framework. It segregates the application into three critical components: Model, View, and Controller.

- **Model** , responsible for managing the data
- **View** , handling the presentation and user interface
- **Controller** , facilitating user interactions and controlling the flow of data.

By clearly defining the roles of these components, MVC ensures a separation of concerns, making code organization and maintenance more systematic.

### Pros & Cons

Following are the pros and cons of MVC architecture:

#### **Pros of MVC**

### Flux

Flux stands as a notable react architectural pattern within the domain of React applications, having been initially introduced by Facebook to tackle the complexities associated with managing intricate data flows. At its essence, Flux is structured around four key components: Actions, Dispatcher, Store, and View. Flux’s unwavering commitment to a unidirectional data flow, simplifying the journey of information throughout the application.

### Key Components of Flux

Flux architecture utilizes a Dispatcher, Actions, Stores, and Views; Actions invoke updates that Dispatcher routes to Stores, which update state and notify Views to re-render, enabling unidirectional data flow for predictable state management in React apps. Let’s take an overview of them:

#### **Actions**

Within the Flux framework, Actions are the embodiments of user interactions and events, acting as the initiators of changes within the application’s state.

#### **Dispatcher**

The Dispatcher plays the role of a conductor in Flux, harmonizing the data flow and guaranteeing that Actions result in precise updates within Stores.

#### **Stores**

Stores act as guardians of the application state, serving as the ultimate authority for data management and logic handling.

#### **Views**

In the Flux realm, Views are responsible for crafting the user interface, using data sourced from Stores as their creative fuel.

### Pros & Cons

Following are the pros and cons of the Flux architecture.

#### **Pros of Flux**

The pros of having Flux architecture are as follows:

**Predictable Data Flow:** Flux imposes a one-way data flow, enhancing the comprehension of data evolution, improving predictability and simplifying debugging.

### [Redux](https://redux.js.org/)

Redux stands as a widely embraced library for state management in JavaScript applications. It furnishes a consistent state repository, where the entire application state converges into a solitary Store. State modifications within Redux are meticulously managed via Actions and Reducers. The potency of Redux stems from this centralized structure and its predictability, which effectively bolsters the management of intricate application states.

### Key Components of Redux

Redux relies on a few essential components that are crucial to grasp. Understanding these basic elements is key to effectively using Redux in your application. These components, including the Store, Actions, and Reducers, serve as the foundation of Redux’s straightforward **[React State Management](https://dev.to/aglowiditsolutions/the-best-react-state-management-tools-for-enterprise-applications-27gb-temp-slug-6035149),** allowing you to manage data flow within your application efficiently.

#### **Store**

The Store serves as a central hub where the entire application’s state is stored.

#### **Actions**

Actions are plain JavaScript objects that detail the alterations needed in the state.

#### **Reducers**

Reducers are pure functions that define how the state should change in response to Actions.

#### **Middleware**

Redux Middleware extends functionality, allowing the handling of side effects like asynchronous tasks or logging.

#### **Unidirectional Data Flow**

Redux architectural pattern enforces unidirectional data flow from the Store to the Views.

#### **Immutable State**

Redux promotes the use of immutable state, where changes result in new state objects rather than modifying the existing ones.

#### **Single Source of Truth**

The Store acts as the sole source of truth, managing the application’s state exclusively.

### React Architecture Best Practices

When working with React, following architectural best practices can help you create more organized, maintainable, and scalable applications. Here are some React architectural pattern best practices:

![React Architecture Best Practices](https://aglowiditsolutions.com/wp-content/uploads/2023/11/React-Architecture-Best-Practices.png)

#### **Navigate a directory structure**

Folders play a pivotal role in structuring your project within management software, ensuring that developers can swiftly locate the resources they need. This hierarchical arrangement offers a vital benefit: it allows developers to grasp all the files associated with a specific feature in one comprehensive view. Moreover, this method simplifies code maintenance and fosters flexibility for reusing code to suit varying project requirements.

To illustrate let’s take the example of a React project

Consider a standard React project that features a “source” (src) directory containing a comprehensive listing of files and folders. Emphasis is placed on adopting a component-centric file structure to streamline development and maintain code integrity.

```

└── /src

├── /assets

├── /components

├── /views

├── /services

├── /utils

├── /hooks

├── /store

└── mydemoApp.js

├── index.js

├── demo.css

```

- The asset folder houses the project’s static assets, including your company’s logo, fonts, images, favicons, and other files.
- The component folder contains the user interface (UI) coding for things like buttons, forms, avatars, etc.
- The views folder contains each and every web page.
- You can communicate with external APIs using the code in the services folder.
- In the utils subdirectory, you can find reusable function snippets.
- The hooks folder contains both new component logic and reusable code.
- The store folder contains files for state management, including Redux.
- The main or regular part of your program is called mydemoApp.js.
- js is the first file of every React application
- css is the name of the application’s primary CSS file for styled elements.

#### **Focus on common modules**

React operates as a framework without a rigid set of coding rules, allowing you the freedom to structure your code as you see fit. This flexibility empowers you to break down your modules in a way that suits your React application’s unique requirements. React is a supportive tool in simplifying the development process and fostering open, reusable, and shareable architectural patterns.

In addressing this, developing custom hooks becomes a valuable strategy. These hooks can effectively bridge the gap between business logic and UI, enhancing code modularity, reusability, and seamless data management. Additionally, you can harness the power of libraries like React Query, which offers custom hooks for handling data fetching, error handling, and content updates. Such tools significantly contribute to a more efficient and maintainable codebase, making them excellent alternatives to **[React Hooks vs Redux](https://dev.to/aglowiditsolutions/react-hooks-vs-redux-best-react-state-management-approach-24n3-temp-slug-647095)** for data management.

#### **Add custom components in folders**

Components are self-contained functional units of your application, providing the essential building blocks for React applications. Organizing these components within designated folders not only streamlines project management but also results in improved organization and navigability. The separation of standard components from custom components promotes reusability, accessibility, and maintainability, which, in turn, contributes to the scalability of your project.

For instance, consider a React custom input component as an example. In the component directory, creating a dedicated folder, say “test,” allows you to organize all relevant files neatly within this subdirectory. This structured approach simplifies the location of component-related resources, making development and maintenance more efficient.

```

└── /src

├── /components

| ├── /test

| | ├── test.js

| | ├── test.css

| | ├── test.testcase.js

```

- js file contains all the logic of the custom component.
- css contains the styled-components part.
- testcase.js comprises all the test cases.

Now, you need to create the index file name it as your preference in the pure components directory, and add the components you want to add. Once the file it setup, you can use this custom component throughout the entire project architecture.

#### **Create custom hooks**

Custom hooks serve as a means to encapsulate and distribute complex state management and side-effect logic across different components. The creation of custom hooks not only maintains the efficiency of your components but also fosters the reuse of intricate logic.

#### **Use absolute imports**

In a typical React application, you often encounter nested structures, which can create confusion when importing elements. For instance:

`// Importing a component`

`import { Button } from '../../components';`

You can implement support for importing modules using absolute paths to eliminate this confusion. This involves configuring a rule in the `jsconfig.json` file situated at the project’s root. The `jsconfig.json` file plays a pivotal role in helping your editor’s Language Server Protocol understand JavaScript and JSX.

Here’s an illustration of how the ``jsconfig.json`` file can simplify the import process:

```
{
  "compilerOptions": {
    "baseUrl": "src"
  },
  "include": ["src"]
}
```

With this rule in place within the `jsconfig.json` file, you can streamline component imports. For instance, to import a component from `/src/components`, you can now employ the following code snippet:

`import { Button } from 'components';`

This practice enhances code readability and eases the navigation process within your React application.

#### **Avoid a single context for everything**

In React applications, a common challenge is sharing data between different components. This can get quite complicated, especially when you have many components in between that need the same data.

To simplify this, React provides a feature called “Context.” Think of it as a way to pass data down through the component tree without manually passing it from one component to another. With Context, a parent component can easily share data with all of its child components, even if there are many layers in between.

Moreover, you can use multiple instances of Context in your React application. This is like having different channels to share data, making your code more robust and allowing you to handle various tasks efficiently. It’s like having multiple communication paths in your application, so you’re not dependent on a single one.

#### **Separate business logic from UI**

It’s crucial to maintain a clear separation between business logic and the user interface for elevating the overall quality of your source code and ensuring seamless software maintenance. Typically, you’ll want to keep the primary user interface components neatly stored in directories like /pages or /views.

In addressing this, developing custom hooks becomes a valuable strategy. These hooks can effectively bridge the gap between business logic and UI, enhancing code modularity and reusability. Additionally, you can harness the power of libraries like React Query, which offers custom hooks for handling data fetching, error handling, and content updates. Such tools significantly contribute to a more efficient and maintainable codebase.

#### **Use the utils directory**

The “utils” directory houses a collection of handy helper functions that can be employed across your entire React application. While utilizing the “utils” directory is not mandatory, it comes highly recommended. This practice contributes to code cleanliness and elevates the overall quality of your software, making it an intelligent choice for efficient and well-maintained projects.
