🚀 How to Share Components Between Sites: A Complete Advanced Guide 🌐

Sharing components across sites or projects is one of the most crucial strategies for modern web development. Whether you're a solo developer or part of a large team, efficient sharing of components leads to:

✅ Code reusability and consistency.

✅ Faster development across projects.

✅ Improved maintainability and scalability.

✅ Seamless collaboration between distributed teams.

In this ultimate guide, we'll explore high-level techniques, tools, workflows, and advanced examples to master the art of sharing components between projects and websites.

🔍 What Do We Mean by "Shared Components"?

Shared components refer to modular pieces of code, often UI components (e.g., buttons, cards, forms), that can be reused across multiple sites. A shared component must be:

  • Independent (no tight coupling with any specific project).
  • Reusable (can fit into multiple projects with minor changes).
  • Maintainable (easy to update and version).

🚀 Why Share Components? Benefits at Scale

Before diving into techniques, let’s explore the key advantages of sharing components:

1. 📦 Efficiency

  • Teams no longer rewrite the same components across different sites.
  • Rapid prototyping and faster time-to-market.

2. 🎨 Consistency in Design

  • Shared components enforce design systems across platforms.
  • Examples: Material-UI, Bootstrap, or custom design libraries.

3. 🔧 Maintainability

  • Updates to shared components reflect everywhere.
  • Centralized fixes prevent repetitive bug resolutions.

4. 🌍 Scalability

  • Projects can scale easily without bloating codebases.
  • Shared repositories can be version-controlled and optimized.

🛠️ Techniques to Share Components Between Sites: The Advanced Guide

Here are the most advanced and effective ways to share components:

1️⃣ Build a Component Library 📦

A component library acts as the single source of truth for shared components. It is a packaged set of components that other projects can install.

Steps to Build an Advanced Component Library

  1. Setup a Monorepo (Optional but Recommended):

    • Use tools like Nx, Lerna, or Yarn Workspaces.
    • A monorepo allows you to manage shared components alongside multiple projects.

  2. Create Modular Components:

    • Use frameworks like React, Vue, or Angular.
    • Write components with TypeScript for better developer experience.

  3. Optimize Bundling:

    • Use Rollup, Webpack, or Vite to bundle components.
    • Generate multiple builds:
      • ES Modules (esm) for modern apps.
      • UMD for legacy applications.

  4. Version and Publish the Library:

    • Use semantic versioning (v1.0.0) to prevent breaking changes.
    • Publish on:
      • npm for public libraries.
      • Verdaccio or GitHub Packages for private libraries.

Advanced Example:

React Component Library with TypeScript:

  1. Initialize the Project: 
npx create-react-library my-library --typescript
Enter fullscreen mode Exit fullscreen mode
  1. Create a Button Component: 
// src/Button/Button.tsx
import React from "react";

export interface ButtonProps {
  label: string;
  onClick?: () => void;
}

export const Button: React.FC<ButtonProps> = ({ label, onClick }) => (
  <button onClick={onClick} style={{ background: "blue", color: "white" }}>
    {label}
  </button>
);
Enter fullscreen mode Exit fullscreen mode
  1. Publish the Library: 
npm login  
npm publish
Enter fullscreen mode Exit fullscreen mode
  1. Install in Another Project: 
npm install my-library
Enter fullscreen mode Exit fullscreen mode

2️⃣ Host Components on a CDN for Global Access 🌐

Instead of publishing components as a package, bundle them and host them on a Content Delivery Network (CDN).

How it Works:

  1. Bundle Components into a single file.
  2. Upload the File to a CDN like AWS S3, Cloudflare, or Vercel Edge Storage.
  3. Access the Component via a <script> tag or dynamic import.

Advanced CDN Example:

Bundling a React Component for CDN:

  1. Bundle Using Rollup: 
npm install --save-dev rollup @rollup/plugin-node-resolve @rollup/plugin-commonjs
Enter fullscreen mode Exit fullscreen mode 
// rollup.config.js
import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';

export default {
  input: "src/Button.js",
  output: {
    file: "dist/button.bundle.js",
    format: "iife",
    name: "SharedButton",
  },
  plugins: [resolve(), commonjs()],
};
Enter fullscreen mode Exit fullscreen mode
  1. Host button.bundle.js on AWS S3: 
https://cdn.mywebsite.com/button.bundle.js
Enter fullscreen mode Exit fullscreen mode
  1. Use in a Project: 
<script src="https://cdn.mywebsite.com/button.bundle.js"></script>
<script>
  const button = SharedButton.Button();
  document.body.append(button);
</script>
Enter fullscreen mode Exit fullscreen mode

3️⃣ Micro-Frontends for Shared Component Deployment 🧩

Micro-frontend architecture allows teams to build independent apps that share components dynamically at runtime.

Advanced Tools for Micro-Frontends:

  1. Webpack Module Federation
  2. Single-SPA Framework
  3. Piral

4️⃣ Use Git Submodules for Code Reuse 📂

A lightweight solution for sharing components is using Git submodules.

  1. Add Shared Components as Submodules: 
git submodule add https://github.com/my-components shared/
Enter fullscreen mode Exit fullscreen mode
  1. Pull Updates in Projects: 
git submodule update --remote
Enter fullscreen mode Exit fullscreen mode

🔧 Advanced Best Practices for Shared Components

  1. Version Control: Use Semantic Versioning to manage updates.
  2. Tree Shaking: Ensure components are optimized for minimal bundle size.
  3. TypeScript: Add type safety for better API contracts.
  4. Documentation: Use tools like Storybook to showcase reusable components.
  5. Testing: Unit test each component with Jest, React Testing Library, or Cypress.

📊 Performance Optimization Tips for Shared Components

  • ✅ Lazy Loading: Import components dynamically.
  • ✅ Code Splitting: Split components into chunks using Webpack.
  • ✅ Minification: Use terser plugins to minimize code size.
  • ✅ CSS-in-JS: Use tools like Styled-Components or Emotion.

🎨 How to Maintain a Component Library in the Long Run

  1. Automate CI/CD Pipelines: Use tools like GitHub Actions to automate builds, testing, and publishing.
  2. Document Component APIs: Use Markdown + Storybook for better DX (Developer Experience).
  3. Ensure Backward Compatibility: Avoid breaking changes by introducing feature flags.

🎯 Conclusion

Sharing components is critical to building maintainable, scalable, and efficient projects. Whether you opt for component libraries, CDN hosting, or micro-frontends, the key is to:

  1. Keep components modular.
  2. Use best practices like tree-shaking and lazy loading.
  3. Document everything for seamless adoption across teams.
