Top 6 React Design Patterns in 2024

There are several design patterns available in React, and we’ve singled out the most favored ones based on their features, functionality, and demand within the developer community. Listed below are the six optimum React design patterns:
1. High Order Components
High Order Components (HOC) represent reusable logic embedded within React components. This widely-adopted React design pattern empowers your development team to integrate additional functionality or features into your React application without altering the original code.

2. Presentational and Container Components

The presentational and container components embody a design pattern strategy that facilitates the segregation of concerns and responsibilities within React applications.
Presentational components are centred on the visual appearance and user experience of a user interface. These components receive data and callbacks through props.
On the flip side, container components take care of responsibilities such as retrieving data from servers, overseeing alterations in data, and handling state management in React applications. Container components guarantee the smooth operation of backend functionalities.
Furthermore, a distinct division between presentational and container components aids in recognizing and fixing errors, leading to a decrease in the application’s downtime.

3. Provider Pattern

As implied by its name, the Provider pattern in React is a software design pattern that disseminates information among various parts of the application. For example, if your website or application necessitates the sharing of data such as user information, the provider pattern facilitates the sharing of that data with the relevant and compliant sections of the application.
Put differently, it serves as the universal repository for your application’s data. Consequently, it enables you to centralize every piece of information, be it business data, user preferences, or any other vital data, in a singular, centralized location.

4. Compound Component Pattern

The composite component pattern empowers your development team to build a set of components that collaborate seamlessly in crafting the application’s user interface. It’s akin to puzzle pieces, where each component plays a specific role, and when assembled, they form a unified user interface. Here are some notable React UI Components and Libraries you might contemplate incorporating into your project.
As a consequence, the user-friendly interface extends the duration of user interaction with your application. Furthermore, composite component patterns can be succinctly described as parent and child components.
The primary and subordinate components collaborate to construct a comprehensive and operational application. The main component orchestrates and manages the subordinate components, and they engage in communication to ensure the seamless performance of the application.

5. React Hooks Components

The most recent iteration of React 16.8 has modified and revolutionized the approach to writing React components. React has unveiled a collection of tools referred to as ‘hooks.’ These hooks enable the components of your application to tackle responsibilities such as managing state and retrieving fresh information.

6. Conditional Rendering Design Pattern

The conditional rendering design pattern exhibits varied content contingent on specific conditions or states within your React.js application. For example, consider three user categories: paid, unpaid, and admin. Utilizing this pattern allows you to adjust user interfaces based on their roles, showcasing distinct displays for each.
Selective rendering is advantageous when your application aims to display pertinent content tailored to diverse users depending on their actions, roles, and preferences. In summary, the React design pattern aids in crafting a user-centric and streamlined application, enhancing customization and user engagement.

3 Advanced React Design Patterns

Are you seeking progress in your React application? If so, contemplate these 3 sophisticated React design patterns as a transformative influence on your project.

1. Render Props Pattern

The Render Props pattern holds the premier position among advanced React.js design patterns. It is a methodology employed by React.js to distribute code and functionality that other components can utilize for the distinctive creation and presentation of elements.

In summary, this pattern acts as a useful instrument that can be distributed to various sections of your application to cultivate new functionality. Additionally, the render props pattern guarantees the uniformity of specific user interface elements across your entire application.

2. State Reducer Pattern

This approach is employed in React applications to handle alterations in state using a predefined set of rules. In a State Reducer pattern, the term ‘state’ encompasses a behavioral design pattern and features a function known as a ‘reducer,’ which oversees the state based on various actions.

So, there’s no need for explicit instructions every time a change occurs; rather, the reducer directs your application on the required actions. Additionally, a state reducer pattern ensures the orderly organization of updated data.

Thus, the state reducer pattern streamlines the testing process, alters the state without impacting other segments of the application, and reduces unwarranted re-renders, resulting in accelerated development.

3. Redux Pattern

The Redux pattern is a potent React.js design pattern that centralizes all information regarding changes in the application in a singular repository. It resembles a book that contains crucial app information, which is accessible throughout various sections of your React application.

This design provides an organized approach to manage and modify the application-wide state, aiding in creating a predictable and manageable data flow. Furthermore, Redux patterns establish a foreseeable sequence of events and oversee the application state in a centralized source. It is apt when the project becomes extensive and more intricate.

Advantages of Using React js Design Patterns
