React is a popular JavaScript library for building user interfaces and it has gained a lot of popularity in recent years as it let you build things in your way instead of following a set of rules like other JavaScript frameworks do and it also allows for greater flexibility in development. and ease of use.

However, as the application grows in size and complexity. It becomes hectic to manage and maintain it.
And this is where React design patterns come into play.

What is the design pattern in react?

A design pattern is a reusable solution to a common problem. In React, they are proven methods to solve common problems experienced by React developers.

Looking to build scalable and maintainable applications with React?

In this blog, we'll explore the top react design patterns that can help you achieve your goal. These popular React designs have been tried and tested, and are known for their effectiveness in building modern web applications.

1. Render Props
   Render props is a design pattern that involves passing a function as a prop to a component, which can then use that function to render its output. This allows for greater flexibility and reusability of components, as the rendering logic is separated from the component itself.

   For example, instead of hard-coding a button component with a specific label, you can use a render prop to dynamically render the label based on the context of the application. This makes the component more flexible and reusable.

2. Higher-Order-Components (HOC)
   The design pattern of higher-order components involves adding extra functionality to components by wrapping it with another component.
   This promotes code reusability and helps to maintain the primary focus of the components

   For example, We can use a Higher Order Function to add authentication or logging capabilities to a component without modifying the original components' code. This makes the component more reusable and easier to maintain.

   Let us see and simple example of HOC

    function multiplyBy(factor) {
     return function(number)
     {
       return number * factor;
     }
    }
    const double = multiplyBy(5);
    console.log(double(5)
    );
   

In the above code snippet, Higher order functions in JavaScript are demonstrated to create new functions with identical functionality but distinct value. The multiplyBy functions generate a new function that multiplies a number bt a specified factor.

3. Container Components Pattern
The main purpose of container components is to transmit data to the presentational components they encapsulate. Typically, container components do not render any additional components except for the presentational components that rely on their data.

The Presentational and Container Component Pattern is based on the idea that components can be better managed if they are separated into two categories - Presentational Components and Container Components.

This pattern aids in creating more maintainable and scalable applications by dividing responsibilities.

1. Compound Components
   Compounds components are a design pattern that involves grouping related components to create a higher-level component. This allows you to create complex UIs by composing smaller components together.

To be more precise we can also say When multiple components work together to have a shared state and handle logic together, they are called compound components.

Think of compound components like the <select> and <option> elements in HTML. Apart they don’t do too much, but together they allow you to create the complete experience.  — Kent C. Dodds

For example, we can use compound components for creating a form that consists of input fields, labels, and buttons. By doing so, it is more convenient to reuse the form throughout the application while keeping the form's logic in a single location.

Conclusion
Again, we wrap everything up by showing that these
React design patterns are essential for building scalable and maintainable applications. By using these best practices, you can build high-quality apps that are easy to maintain and extend. Whether you're building a small application or a large enterprise app, these design patterns will help you build better software.

In this article, we discussed various React design patterns such as render props, higher-order components, container-component patterns, and compound components. Employing these design patterns in our React development we can take our React development to the next level and build amazing applications.

Till then Happy Learning 😊😊
