How to Implement SSR for Static Site Generation

Implement Server-Side Rendering (SSR) for static site generation. Follow our guide to combine the benefits of SSR and static sites for optimal performance and SEO.

Static site generation (SSG) is a powerful method for creating fast, secure, and scalable websites. By pre-rendering pages at build time, SSG delivers HTML files that can be served quickly to users. Server-Side Rendering (SSR) enhances this process by generating HTML on the server before sending it to the client. Combining SSR with SSG allows you to create dynamic websites that perform like static ones. This article will guide you through the process of implementing SSR for static site generation, providing detailed, actionable insights to help you achieve optimal results.

Understanding Static Site Generation and SSR

Before diving into implementation, it’s essential to understand the concepts of static site generation and server-side rendering and how they complement each other.

Before diving into implementation, it’s essential to understand the concepts of static site generation and server-side rendering and how they complement each other.

What is Static Site Generation?

Static site generation involves building web pages at compile time rather than at runtime. This means that HTML, CSS, and JavaScript files are generated once and served directly to users, eliminating the need for server-side processing on each request.

This approach results in faster load times, improved security, and reduced server costs.

Benefits of Static Site Generation

Static site generation offers several advantages, including enhanced performance, better security, and simplified hosting. Since the content is pre-rendered and served as static files, there’s no need for server-side processing, which reduces the risk of vulnerabilities and improves scalability.

What is Server-Side Rendering?

Server-Side Rendering (SSR) involves generating HTML on the server for each request and sending it to the client. This process allows the browser to display content immediately without waiting for JavaScript to load and execute.

SSR improves the time to first meaningful paint (TTFMP) and enhances SEO by providing fully rendered HTML for search engines to crawl.

Combining SSR with Static Site Generation

Combining SSR with SSG allows you to build static sites that can handle dynamic content. This hybrid approach generates static files at build time and dynamically renders pages on the server when needed.

This combination provides the best of both worlds: the speed and security of static sites with the flexibility and interactivity of dynamic content.

Setting Up Your Development Environment

To implement SSR for static site generation, you need to set up your development environment with the necessary tools and frameworks. The following sections will guide you through the process.

Choosing the Right Framework

Several frameworks support SSR and static site generation, including Next.js for React, Nuxt.js for Vue.js, and Sapper for Svelte. Choose a framework that aligns with your technology stack and development needs. These frameworks provide built-in support for SSR and SSG, making it easier to implement and manage your project.

Installing Dependencies

Once you’ve chosen your framework, install the necessary dependencies. For example, if you’re using Next.js, you’ll need to install Node.js, Next.js, and other related packages. Follow the official documentation for your chosen framework to ensure a smooth setup process.

# Example for Next.js
npm install next react react-dom

Setting Up Your Project

After installing the dependencies, set up your project by creating the necessary files and directories. Follow the framework’s guidelines to structure your project correctly. For Next.js, this involves creating a pages directory to store your page components and a public directory for static assets.

# Example for Next.js
mkdir my-next-app
cd my-next-app
npx create-next-app .

Implementing SSR for Static Site Generation

With your development environment set up, you can start implementing SSR for static site generation. This process involves configuring your server, optimizing your code, and ensuring that your site is both performant and scalable.

Configuring Your Server

Configuring your server to handle SSR is crucial for generating and serving pre-rendered HTML pages. Depending on your framework, this may involve setting up a custom server or using built-in server functions.

Example with Next.js

Next.js provides a built-in server that supports SSR out of the box. To configure your server, create a custom server file (e.g., server.js) and use it to handle requests and render pages.

// Example for Next.js
const express = require('express');
const next = require('next');

const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev });
const handle = app.getRequestHandler();

app.prepare().then(() => {
  const server = express();

  server.get('*', (req, res) => {
    return handle(req, res);
  });

  server.listen(3000, (err) => {
    if (err) throw err;
    console.log('> Ready on http://localhost:3000');
  });
});

Optimizing Your Code for SSR

Optimizing your code for SSR is essential for achieving the best performance and user experience. Ensure that your components are server-renderable, manage state correctly, and avoid browser-specific APIs that may not work on the server.

Component Optimization

When building components for SSR, ensure they can render on the server without relying on client-specific APIs. For example, avoid using window or document directly in your components. Instead, use conditional logic to check if the code is running on the server or client.

// Example for Next.js
import { useEffect, useState } from 'react';

const ExampleComponent = () => {
  const [clientOnly, setClientOnly] = useState(false);

  useEffect(() => {
    setClientOnly(true);
  }, []);

  return (
    <div>
      {clientOnly ? <p>Client-side content</p> : <p>Server-side content</p>}
    </div>
  );
};

export default ExampleComponent;

Managing State in SSR

State management in SSR involves ensuring that both the server and client have access to the same data. Use state management libraries that support SSR, such as Redux or Context API, to manage state across your application.

Example with Redux

If you’re using Redux, set up your store to be initialized on the server and rehydrated on the client. This approach ensures that the server and client share the same state.

// Example for Next.js with Redux
import { createStore } from 'redux';
import { Provider } from 'react-redux';
import App from 'next/app';

const reducer = (state = { count: 0 }, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return { count: state.count + 1 };
    default:
      return state;
  }
};

const makeStore = () => createStore(reducer);

class MyApp extends App {
  static async getInitialProps({ Component, ctx }) {
    const store = makeStore();
    ctx.store = store;

    const pageProps = Component.getInitialProps
      ? await Component.getInitialProps(ctx)
      : {};

    return { pageProps, initialReduxState: store.getState() };
  }

  render() {
    const { Component, pageProps, initialReduxState } = this.props;
    const store = makeStore(initialReduxState);

    return (
      <Provider store={store}>
        <Component {...pageProps} />
      </Provider>
    );
  }
}

export default MyApp;

Fetching Data for SSR

Fetching data efficiently is a crucial part of implementing SSR for static site generation. Ensuring that data is available on the server before rendering the page improves performance and user experience.

Data Fetching Methods

Different frameworks offer various methods for fetching data during server-side rendering. It’s essential to choose the method that best fits your needs and integrates well with your framework.

Next.js Example

Next.js provides getServerSideProps and getStaticProps functions for fetching data during server-side rendering and static generation, respectively.

Using getServerSideProps

getServerSideProps runs on the server side and fetches data for each request, which is useful for dynamic content that changes frequently.

// Example of getServerSideProps
export async function getServerSideProps() {
  const res = await fetch('https://api.example.com/data');
  const data = await res.json();

  return {
    props: { data },
  };
}

const Page = ({ data }) => {
  return (
    <div>
      <h1>Server-Side Rendered Page</h1>
      <pre>{JSON.stringify(data, null, 2)}</pre>
    </div>
  );
};

export default Page;

Using getStaticProps

getStaticProps is used for static generation and runs at build time, making it suitable for content that doesn’t change often.

// Example of getStaticProps
export async function getStaticProps() {
  const res = await fetch('https://api.example.com/data');
  const data = await res.json();

  return {
    props: { data },
  };
}

const Page = ({ data }) => {
  return (
    <div>
      <h1>Statically Generated Page</h1>
      <pre>{JSON.stringify(data, null, 2)}</pre>
    </div>
  );
};

export default Page;

Handling API Rate Limits and Errors

When fetching data from APIs, you may encounter rate limits and errors. It’s important to implement error handling and retry mechanisms to ensure that your application remains robust.

Example Error Handling

Implement error handling in your data fetching functions to manage API errors gracefully.

export async function getServerSideProps() {
  try {
    const res = await fetch('https://api.example.com/data');
    if (!res.ok) {
      throw new Error('Failed to fetch data');
    }
    const data = await res.json();

    return {
      props: { data },
    };
  } catch (error) {
    console.error(error);
    return {
      props: { data: null },
    };
  }
}

Caching API Responses

Caching API responses can improve performance by reducing the number of requests to external services. Use caching strategies to store frequently accessed data and serve it quickly.

Example Caching with Next.js

Implement caching in your data fetching functions to store and retrieve data efficiently.

const cache = new Map();

export async function getServerSideProps() {
  const cacheKey = 'apiData';
  if (cache.has(cacheKey)) {
    return {
      props: { data: cache.get(cacheKey) },
    };
  }

  try {
    const res = await fetch('https://api.example.com/data');
    if (!res.ok) {
      throw new Error('Failed to fetch data');
    }
    const data = await res.json();
    cache.set(cacheKey, data);

    return {
      props: { data },
    };
  } catch (error) {
    console.error(error);
    return {
      props: { data: null },
    };
  }
}

SEO Optimization with SSR and SSG

SEO (Search Engine Optimization) is a critical aspect of web development, and SSR combined with SSG offers significant benefits for improving your site’s visibility in search engine results.

SEO (Search Engine Optimization) is a critical aspect of web development, and SSR combined with SSG offers significant benefits for improving your site’s visibility in search engine results.

Pre-rendered Content

One of the primary benefits of SSR and SSG is delivering pre-rendered HTML to the browser, which search engines can crawl and index more effectively than client-rendered content.

Meta Tags and Structured Data

Proper use of meta tags and structured data can enhance SEO by providing search engines with detailed information about your content. Ensure that your SSR implementation includes the necessary meta tags for each page.

Example with Next.js

Use the Head component from Next.js to include meta tags and structured data in your pages.

import Head from 'next/head';

const Page = ({ data }) => {
  return (
    <div>
      <Head>
        <title>{data.title}</title>
        <meta name="description" content={data.description} />
        <script type="application/ld+json">
          {JSON.stringify({
            "@context": "http://schema.org",
            "@type": "WebPage",
            "name": data.title,
            "description": data.description,
          })}
        </script>
      </Head>
      <h1>{data.title}</h1>
      <p>{data.description}</p>
    </div>
  );
};

export default Page;

Sitemap and Robots.txt

Generating a sitemap and configuring your robots.txt file correctly can help search engines understand and crawl your site more effectively.

Generating a Sitemap

Create a dynamic sitemap by generating a sitemap.xml file based on your site’s content.

// Example for Next.js
import { SitemapStream, streamToPromise } from 'sitemap';
import { createGzip } from 'zlib';
import { Readable } from 'stream';

export async function getServerSideProps({ res }) {
  const sitemap = new SitemapStream({ hostname: 'https://example.com' });
  const xmlString = await streamToPromise(Readable.from([
    { url: '/', changefreq: 'daily', priority: 1.0 },
    { url: '/about', changefreq: 'monthly', priority: 0.8 },
  ]).pipe(sitemap)).then((data) => data.toString());

  res.setHeader('Content-Type', 'application/xml');
  res.setHeader('Content-Encoding', 'gzip');
  res.write(createGzip().end(xmlString));
  res.end();

  return {
    props: {},
  };
}

Mobile Optimization

Ensuring that your site is mobile-friendly is crucial for SEO, as search engines prioritize mobile-optimized sites. Use responsive design techniques and test your site on various devices to ensure a seamless mobile experience.

Responsive Design

Implement responsive design in your CSS to ensure that your site adapts to different screen sizes and devices.

/* Example responsive CSS */
body {
  font-family: Arial, sans-serif;
  margin: 0;
  padding: 0;
}

.container {
  width: 100%;
  max-width: 1200px;
  margin: 0 auto;
  padding: 20px;
}

@media (max-width: 600px) {
  .container {
    padding: 10px;
  }
}

Enhancing User Experience with SSR and SSG

A significant advantage of combining SSR with SSG is the ability to provide a fast, seamless user experience. Ensuring quick load times and smooth interactions are crucial for retaining users and improving engagement.

Improving Load Times

Fast load times are essential for a good user experience. SSR helps by delivering pre-rendered HTML to the client, which speeds up the time to first meaningful paint (TTFMP). Additionally, SSG ensures that static files are served quickly from the server or CDN.

Lazy Loading

Lazy loading is a technique to defer the loading of non-critical resources until they are needed. This reduces the initial load time and improves performance.

Example with Next.js

Use the next/image component to implement lazy loading for images in Next.js.

import Image from 'next/image';

const Page = () => {
  return (
    <div>
      <h1>Image with Lazy Loading</h1>
      <Image
        src="/path/to/image.jpg"
        alt="Description"
        width={500}
        height={300}
        loading="lazy"
      />
    </div>
  );
};

export default Page;

Enhancing Interactivity

Interactive elements can significantly enhance user experience. SSR can pre-render these elements on the server, ensuring that they are interactive as soon as the page loads.

Hydration

Hydration is the process of attaching event listeners to the pre-rendered HTML, making it interactive. Ensure that your components are designed to hydrate correctly.

Example with React and Next.js

Ensure your components are ready for hydration by managing state correctly and using React hooks.

import { useState, useEffect } from 'react';

const InteractiveComponent = () => {
  const [count, setCount] = useState(0);

  useEffect(() => {
    console.log('Component hydrated');
  }, []);

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>Increment</button>
    </div>
  );
};

export default InteractiveComponent;

Handling Dynamic Content

Dynamic content that changes frequently can still be optimized with SSR. By fetching data on the server and rendering it before sending it to the client, you ensure that users receive up-to-date information without delays.

Example with Next.js and API Fetching

Fetch dynamic data on the server and render it in your components.

export async function getServerSideProps() {
  const res = await fetch('https://api.example.com/dynamic-data');
  const data = await res.json();

  return {
    props: { data },
  };
}

const DynamicPage = ({ data }) => {
  return (
    <div>
      <h1>Dynamic Data</h1>
      <pre>{JSON.stringify(data, null, 2)}</pre>
    </div>
  );
};

export default DynamicPage;

Deploying SSR and SSG Applications

Deploying applications that use SSR and SSG involves specific considerations to ensure they run efficiently in a production environment.

Choosing the Right Hosting Platform

Selecting a hosting platform that supports SSR and SSG is crucial for optimal performance. Platforms like Vercel, Netlify, and AWS offer excellent support for these technologies.

Deploying on Vercel

Vercel provides seamless integration with Next.js, making it an ideal choice for deploying SSR and SSG applications.

# Deploying Next.js on Vercel
vercel

Configuring Caching and CDN

Configuring caching and using a Content Delivery Network (CDN) can significantly improve the performance of your deployed application. CDNs distribute your static files across multiple locations, ensuring that users can access them quickly from the nearest server.

Configuring Caching Headers

Set caching headers to control how long static assets and pages are cached by the client and CDN.

// Example in Next.js
export async function getServerSideProps(context) {
  context.res.setHeader('Cache-Control', 'public, s-maxage=10, stale-while-revalidate=59');
  const res = await fetch('https://api.example.com/data');
  const data = await res.json();

  return {
    props: { data },
  };
}

const Page = ({ data }) => {
  return (
    <div>
      <h1>Page with Caching</h1>
      <pre>{JSON.stringify(data, null, 2)}</pre>
    </div>
  );
};

export default Page;

Continuous Integration and Deployment (CI/CD)

Implementing CI/CD pipelines ensures that your application is automatically tested and deployed whenever you make changes. This approach helps maintain high-quality code and reduces the risk of deploying broken features.

Setting Up a CI/CD Pipeline

Use services like GitHub Actions, CircleCI, or Travis CI to set up automated testing and deployment for your application.

Example with GitHub Actions

Create a GitHub Actions workflow file to automate testing and deployment.

# .github/workflows/ci.yml
name: CI

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - name: Install dependencies
        run: npm install
      - name: Run tests
        run: npm test
      - name: Deploy to Vercel
        run: vercel --prod
        env:
          VERCEL_TOKEN: ${{ secrets.VERCEL_TOKEN }}

Monitoring and Maintaining SSR and SSG Applications

Once your application is deployed, continuous monitoring and maintenance are essential to ensure it runs smoothly and efficiently.

Performance Monitoring

Use performance monitoring tools to track the load times, responsiveness, and overall performance of your application. Services like Google Analytics, New Relic, and Datadog can provide valuable insights.

Implementing Performance Monitoring

Set up performance monitoring in your application to track critical metrics.

// Example with Google Analytics
import { useEffect } from 'react';
import { useRouter } from 'next/router';

const usePageView = () => {
  const router = useRouter();

  useEffect(() => {
    const handleRouteChange = (url) => {
      window.gtag('config', 'GA_TRACKING_ID', {
        page_path: url,
      });
    };

    router.events.on('routeChangeComplete', handleRouteChange);

    return () => {
      router.events.off('routeChangeComplete', handleRouteChange);
    };
  }, [router.events]);
};

const MyApp = ({ Component, pageProps }) => {
  usePageView();

  return <Component {...pageProps} />;
};

export default MyApp;

Error Tracking

Error tracking tools help identify and fix issues in your application. Use services like Sentry or Rollbar to track errors and exceptions in both server-side and client-side code.

Setting Up Error Tracking

Integrate error tracking into your application to catch and resolve issues quickly.

// Example with Sentry
import * as Sentry from '@sentry/node';
import { Integrations } from '@sentry/tracing';

Sentry.init({
  dsn: 'YOUR_SENTRY_DSN',
  integrations: [new Integrations.BrowserTracing()],
  tracesSampleRate: 1.0,
});

Regular Updates and Maintenance

Keep your dependencies up-to-date and regularly review your codebase to ensure it remains secure and efficient. Use automated tools to notify you of outdated or vulnerable dependencies.

Automated Dependency Updates

Set up tools like Dependabot to automatically update dependencies in your project.

# .github/dependabot.yml
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "daily"

Security Considerations for SSR and SSG

Security is a critical aspect of web development, especially when dealing with dynamic content and user interactions. Implementing SSR for SSG introduces several security considerations that must be addressed to protect your application and its users.

Security is a critical aspect of web development, especially when dealing with dynamic content and user interactions. Implementing SSR for SSG introduces several security considerations that must be addressed to protect your application and its users.

Data Sanitization and Validation

One of the primary concerns when dealing with SSR is ensuring that any data rendered on the server is safe and does not introduce vulnerabilities such as Cross-Site Scripting (XSS) attacks. Proper data sanitization and validation are essential.

Sanitizing Data

Sanitize any user input or external data before rendering it on the server. Use libraries like DOMPurify for sanitizing HTML to prevent XSS attacks.

import DOMPurify from 'dompurify';

const safeHTML = DOMPurify.sanitize('<script>alert("XSS");</script>'); // This will remove the script tag

Validating Data

Validate data to ensure it meets expected formats and constraints before processing it on the server. This step helps prevent injection attacks and other malicious activities.

const validateInput = (input) => {
  const isValid = /^[a-zA-Z0-9]+$/.test(input);
  if (!isValid) {
    throw new Error('Invalid input');
  }
  return input;
};

Authentication and Authorization

Handling authentication and authorization securely is crucial for protecting sensitive user data and ensuring that only authorized users can access certain features or resources.

Implementing Authentication

Use secure authentication mechanisms such as JWT (JSON Web Tokens) or OAuth to manage user sessions. Ensure that tokens are stored securely and transmitted over HTTPS.

import jwt from 'jsonwebtoken';

const token = jwt.sign({ userId: user.id }, process.env.JWT_SECRET, { expiresIn: '1h' });

Managing Authorization

Implement role-based access control (RBAC) to manage permissions and restrict access to certain resources based on user roles.

const authorize = (user, role) => {
  if (!user.roles.includes(role)) {
    throw new Error('Unauthorized');
  }
};

Secure API Communication

Ensure that communication between your server and external APIs or microservices is secure. Use HTTPS to encrypt data in transit and authenticate API requests to prevent unauthorized access.

Configuring HTTPS

Configure your server to use HTTPS and obtain an SSL certificate from a trusted certificate authority (CA).

import https from 'https';
import fs from 'fs';

const options = {
  key: fs.readFileSync('path/to/private-key.pem'),
  cert: fs.readFileSync('path/to/certificate.pem'),
};

https.createServer(options, app).listen(443, () => {
  console.log('Server is running on https://localhost:443');
});

Implementing Content Security Policy (CSP)

A Content Security Policy (CSP) helps prevent various types of attacks, including XSS and data injection attacks, by specifying which sources of content are allowed to be loaded by the browser.

Setting Up CSP Headers

Configure your server to include CSP headers in the HTTP response.

app.use((req, res, next) => {
  res.setHeader(
    'Content-Security-Policy',
    "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; object-src 'none'; style-src 'self' 'unsafe-inline';"
  );
  next();
});

Performance Optimization Strategies

Ensuring that your SSR and SSG application performs well is essential for providing a positive user experience. Implementing performance optimization strategies can help achieve this goal.

Minimizing JavaScript and CSS

Minimizing the size of JavaScript and CSS files can significantly improve load times. Use tools like Webpack to bundle and minify these assets.

Using Webpack for Minification

Configure Webpack to minify JavaScript and CSS files during the build process.

const TerserPlugin = require('terser-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
  mode: 'production',
  optimization: {
    minimize: true,
    minimizer: [new TerserPlugin()],
  },
  plugins: [new MiniCssExtractPlugin()],
};

Code Splitting

Code splitting involves breaking down your JavaScript bundles into smaller chunks that can be loaded on demand, reducing the initial load time.

Implementing Code Splitting with Webpack

Configure Webpack to split code into smaller chunks.

module.exports = {
  optimization: {
    splitChunks: {
      chunks: 'all',
    },
  },
};

Lazy Loading Images and Components

Lazy loading helps defer the loading of non-critical resources until they are needed, improving the initial load time and overall performance.

Implementing Lazy Loading for Images

Use the loading="lazy" attribute in HTML to defer loading of images.

<img src="path/to/image.jpg" alt="Description" loading="lazy" />

Lazy Loading Components in React

Use dynamic imports to lazy load React components.

import React, { Suspense, lazy } from 'react';

const LazyComponent = lazy(() => import('./LazyComponent'));

const App = () => (
  <Suspense fallback={<div>Loading...</div>}>
    <LazyComponent />
  </Suspense>
);

export default App;

Optimizing Server Response Time

Improving server response time is crucial for fast page loads. Optimize your server configuration and database queries to reduce latency.

Database Query Optimization

Ensure that your database queries are efficient and indexed properly to minimize response times.

// Example query optimization with indexing
db.collection.createIndex({ field: 1 });
const results = db.collection.find({ field: 'value' });

Utilizing a Content Delivery Network (CDN)

A CDN can distribute your static files across multiple locations worldwide, ensuring that users can access them quickly from the nearest server.

Configuring CDN with Next.js

Use a CDN to serve static assets in a Next.js application.

// next.config.js
module.exports = {
  images: {
    domains: ['your-cdn-domain.com'],
  },
};

The landscape of web development is constantly evolving, and staying ahead of the latest trends can help you maintain a competitive edge. Here are some emerging trends in SSR and SSG that are shaping the future of web development.

Edge Computing

Edge computing involves processing data closer to the user, reducing latency and improving performance. Integrating SSR with edge computing can further enhance the speed and responsiveness of your web applications.

Edge Computing with Vercel

Vercel’s edge functions allow you to run serverless functions at the edge, providing low-latency SSR.

// Example edge function with Vercel
export default async (req, res) => {
  const data = await fetch('https://api.example.com/data').then((response) => response.json());
  res.status(200).json(data);
};

Serverless Architectures

Serverless architectures enable you to build and deploy applications without managing servers, providing scalability and cost efficiency. Combining SSR with serverless functions can streamline your deployment process.

Using Serverless with AWS Lambda

Deploy SSR applications using AWS Lambda to take advantage of serverless architecture.

// Example AWS Lambda function
exports.handler = async (event) => {
  const data = await fetch('https://api.example.com/data').then((response) => response.json());
  return {
    statusCode: 200,
    body: JSON.stringify(data),
  };
};

Progressive Web Apps (PWAs)

Progressive Web Apps (PWAs) provide a native app-like experience on the web. Combining SSR with PWAs can enhance performance, offline capabilities, and user engagement.

Implementing PWA with Next.js

Configure your Next.js application to be a PWA.

// next.config.js
const withPWA = require('next-pwa');

module.exports = withPWA({
  pwa: {
    dest: 'public',
  },
});

WebAssembly (Wasm)

WebAssembly (Wasm) enables high-performance applications on the web by allowing code written in multiple languages to run in the browser. Integrating Wasm with SSR can provide a significant performance boost for computationally intensive tasks.

Using WebAssembly with JavaScript

Compile and use WebAssembly in a JavaScript application.

// Example of using WebAssembly
fetch('module.wasm')
  .then((response) => response.arrayBuffer())
  .then((bytes) => WebAssembly.instantiate(bytes))
  .then((results) => {
    const { instance } = results;
    console.log(instance.exports.add(1, 2));
  });

Conclusion

Implementing Server-Side Rendering (SSR) for Static Site Generation (SSG) offers a powerful way to create fast, scalable, and dynamic web applications.
