Understanding React Rendering: An Overview of Types
Published: 2023-08-03 09:34:01

React rendering transforms React components and elements into an apparent user interface on a web page or mobile application. Facebook created the well-known JavaScript package React, which is used to create dynamic and interactive user interfaces. Creating reusable, component-based user interfaces that quickly update and reflect changes in the application's data is made possible through rendering, an essential component of React's functionality.

The rendering of components in React relies on a virtual DOM. This process prevents direct alteration of the actual DOM; React generates a virtual version in memory instead. Any alterations made to the data or state of the application undergo a "diffing" process by React to detect the necessary changes required to update the virtual DOM. These changes are then applied cost-effectively to the actual DOM, reducing the number of pricey DOM manipulations.


## Types of React Rendering

To fully understand React's rendering process, first, let us know the types: 

### 1. CSR: Client-Side Rendering
The complete React application is loaded as a bundle in the user's browser during client-side rendering. The program dynamically collects data from APIs to populate the content rendered on the client side.

CSR offers a quick and engaging user experience after loading the initial bundle. It might be a wise solution for programs that need constant data updates but don't rely much on SEO. More extensive programs, however, could take slower to load initially, and SEO might be more challenging.

### 2. Server Side Rendering
During server-side rendering, React components are initially rendered on the server side and then sent to the client's browser. The browser receives the produced material, which then turns interactive and retrieves any further dynamic data.

Since search engines can index the pre-rendered information, SSR improves initial load times and offers better SEO. For content-intensive applications and e-commerce websites, in particular, it can increase user engagement and search engine exposure.

### 3. Static Site Generation
The React application is pre-rendered to static HTML during construction in static site generation, a form of server-side rendering. Without running server-side processing, the pre-rendered material is served immediately to users.

SSG provides significant performance and security advantages. There is no server-side processing for each request, so it guarantees quick page loads. SSG can be the best option for hosting costs and user experience reduction for content-focused websites, blogs, and landing pages.

### 4. Incremental Static Regeneration
ISR has improved the creation of static sites. It enables specific pages to be generated periodically or in response to certain events (like adding fresh material). The remaining pages continue to be statically provided.

ISR might be useful for websites with constantly updated information. This approach combines the benefits of static site generation with the ability to update information without rebuilding the entire site.

### 5. Hybrid Rendering
The hybrid rendering technique is a brilliant combination of two renderings, effectively harnessing the advantages of both methods. The most effective way to render web pages is through hybrid rendering, which combines client and server-side rendering. The React application is partially rendered on the server for the initial load and to improve SEO, while other parts are rendered on the client side for interactivity.

A technique called hybrid rendering can offer a good balance between speed, search engine optimization, and interactive user experiences. This approach is beneficial for applications that feature a combination of static content and frequently updated data.

To make educated choices regarding the development methodology that best satisfies their application's requirements, user experience, and commercial objectives, business owners must be aware of the many forms of React rendering. Each rendering type has its unique advantages and considerations, which is why it's crucial to evaluate the application's specific needs before settling on a rendering strategy.


## Conclusion
React rendering is an essential and potent component of the React toolkit, enabling programmers to create dynamic and interactive user interfaces quickly. The rendering method used by React is based on the idea of a virtual DOM, which serves as a bridge between the state of the application and the actual DOM, or the HTML structure of the web page.
