Overview:

This project is a React Server Side Rendering (SSR) Boilerplate. It provides a setup for building fully featured, server-rendered React applications. It includes server-side rendering with code splitting, server-side data fetching, React Router, conditional loading of polyfills, React Helmet for dynamic manipulation of the document head, a development server with hot reloading styles, Jest and react-testing-library for testing, CSS Modules, Sass, autoprefixer, support for runtime environment variables, Node.js clusters for improved performance under load in production, Prettier and ESLint for code formatting and linting, and Docker support for production deployment.

Features:

• Server-side rendering with code splitting: Utilizes the React Loadable package for code splitting during server-side rendering.
• Server-side data fetching and client-side hydration: Fetches data on the server-side and hydrates the client-side React application.
• React Router: Supports routing in the React application.
• Conditionally load polyfills: Loads polyfills only for outdated browsers to reduce bundle size.
• React Helmet: Allows dynamic manipulation of the document head.
• Dev server with hot reloading styles: Provides a development server with hot reloading for styles during development.
• Jest and react-testing-library: Includes testing tools for writing tests for the React application.
• CSS Modules, Sass, and autoprefixer: Supports CSS Modules, Sass preprocessor, and autoprefixer for CSS styling.
• Runtime environment variables: Supports handling environment variables at runtime.
• Node.js clusters for improved performance: Utilizes Node.js clusters to improve performance under load in production.
• Prettier and ESLint run on commit: Applies code formatting using Prettier and linting using ESLint before committing code.
• Docker-ized for production: Provides support for building and deploying the application using Docker.

Installation:

To install the React Server Side Rendering Boilerplate, follow these steps:

1. Clone the repository: git clone [repository-url]
2. Install dependencies: npm install
3. For development, start the development server: npm start
4. For testing, run Jest in watch mode: npm test
5. For production, bundle the JS and start the Express server: npm run build && npm run start:prod
6. To build and start a local Docker image in production mode (for debugging): npm run docker

Summary:

The React Server Side Rendering Boilerplate provides a comprehensive setup for building server-rendered React applications. It includes features like code splitting, server-side data fetching, routing, polyfill loading, dynamic manipulation of the document head, development server with hot reloading, testing tools, CSS styling options, environment variable support, performance optimization, code formatting, and Docker deployment. This boilerplate simplifies the process of transitioning to server-side rendering in React applications and provides a solid foundation for building fully featured React apps.
