Client-Side Rendering (CSR)

Jamstack Architecture

Creating a detailed summary on Server-Side Rendering (SSR) in MediaWiki syntax, including all the requested details, would result in an extensive document. Here, I'll provide a structured summary that touches on key points such as main features, code examples, popular third-party libraries, and alternatives, focusing on the context of web development.

Server-Side Rendering refers to the process of rendering web pages on the server instead of in the browser. This approach can significantly improve the performance of web applications, particularly in terms of speed to first paint and search engine optimization (SEO). SSR is often used in frameworks and libraries such as Next.js, Nuxt.js, and Angular Universal.

SSR comes with several notable features that enhance web application performance and user experience: - **Improved SEO**: Since the content is rendered on the server, search engines can crawl the site more effectively. - **Faster Initial Page Load**: Users see the content sooner because the HTML is fully rendered once it arrives from the server. - **Better Performance on Low-Power Devices**: Devices with less processing power don't have to spend as much time rendering complex applications. - **Consistent SEO Performance Across Search Engines**: Ensures content is indexed even by search engines that do not execute JavaScript well.

Next.js is a React framework that provides out-of-the-box support for SSR, making it easier to build performant React applications that benefit from server-side rendering.

The Next.js GitHub repository is a rich resource for developers looking to understand the framework's capabilities, contribute, or need to report an issue. URL: s://github.com/vercel/next.js(https://github.com/vercel/next.js)

Official documentation for Next.js offers a comprehensive guide on how to effectively use the framework, including its SSR features. URL: s://nextjs.org/docs(https://nextjs.org/docs)

The official website for Next.js provides an overview of the framework, including tutorials, case studies, and documentation. URL: s://nextjs.org/(https://nextjs.org/)

Here are 8 code examples that illustrate how SSR can be implemented or utilized in various frameworks:

```jsx import { GetServerSideProps } from 'next'

export const getServerSideProps: GetServerSideProps = async context ⇒ {

 // Fetch data from an API or database
 const data = await fetchData();
 return { props: { data } };

function Page({ data }) {

 return 
{data}
;

export default Page; ```

```jsx import { GetServerSideProps } from 'next'

export const getServerSideProps: GetServerSideProps = async () ⇒ {

 const res = await fetch(`https://api.example.com/data`)
 const data = await res.json()

 return {
   props: {
     data,
   },
 }

function HomePage({ data }) {

 return (
   

     {data.map((item) => (
       
{item.title}
     ))}
   
 )

export default HomePage; ```

```javascript import express from 'express'; import ReactDOMServer from 'react-dom/server'; import App from './App';

const server = express();

server.use('^/$', (req, res, next) ⇒ {

 const app = ReactDOMServer.renderToString();
 res.send(`
   
     
       
${app}
     
   
 `);

server.listen(3000); ```

```typescript // server.ts import 'zone.js/dist/zone-node'; import { ngExpressEngine } from '@nguniversal/express-engine'; import * as express from 'express'; import { AppServerModule } from './src/main.server';

const app = express(); app.engine('html', ngExpressEngine({

 bootstrap: AppServerModule,

app.set('view engine', 'html'); app.set('views', 'dist/browser');

app.get('*', (req, res) ⇒ {

 res.render('index', { req });

app.listen(4000, () ⇒ {

 console.log(`Angular Universal server is listening on port 4000`);

```vue <template>

 

   
{{ title }}
   
{{ content }}
 

<script> export default {

 async asyncData({ params }) {
   const { data } = await axios.get(`https://api.example.com/posts/${params.id}`);
   return { title: data.title, content: data.content };
 }

In scenarios where SSR is not required for every request, static site generation can be a complementary approach. Tools like Next.js and Gatsby provide functionalities to pre-render pages at build time.

Implementing caching mechanisms on the server can significantly improve SSR performance by serving pre-rendered content for frequent requests without the need to render them on each request.

Dynamic imports can be used in server-side rendered applications to split the code and only load what's necessary for rendering the initial view, improving load times.

Integrating SSR with third-party libraries can enhance its capabilities: 1. **Redux**: For managing application state in React apps with SSR. 2. **Apollo**: For integrating GraphQL in SSR applications. 3. **Next-Redux-Wrapper**: For easier integration of Redux with Next.js. 4. **Vue Server Renderer**: For SSR in Vue applications. 5. **Angular Universal**: For SSR with Angular applications.

While SSR offers numerous benefits, there are alternatives and complementary technologies: - **Static Site Generators (SSG)**: Tools like Gatsby (React) and Jekyll (Ruby) pre-render pages at build time. - **Client-Side Rendering (CSR)**: Traditional client-side JavaScript frameworks and libraries, such as React, Vue, and Angular, can be used purely on the client-side. - **Jamstack Architecture**: Combines the best of both worlds with pre-rendering and serverless functions for dynamic content. - **Hybrid Rendering**: Some frameworks, like Next.js, offer both SSR and static generation, allowing developers to choose the best approach for each page.

SSR remains a critical technology for web developers aiming to improve the performance, SEO, and user experience of their applications. By leveraging SSR capabilities within modern web development frameworks and understanding the trade-offs compared to

alternatives, developers can create efficient, fast-loading, and SEO-friendly web applications.
