Tools for UI Decomposition in Micro Frontends

1. Introduction

Micro frontends allow developers to break up monolithic frontend applications into smaller, more manageable pieces. UI decomposition is crucial for achieving this modularity. In this lesson, we will explore various tools that can assist in UI decomposition.

2. Key Concepts

• Micro Frontends: An architectural style where a single application is composed of multiple smaller applications.
• UI Decomposition: The process of dividing UI components into smaller, reusable units.
• Independent Deployment: The ability to deploy each micro frontend independently without affecting others.

3. Decomposition Tools

There are several tools and frameworks available for effective UI decomposition in micro frontends:

            // webpack.config.js
            module.exports = {
                // other configurations
                plugins: [
                    new ModuleFederationPlugin({
                        name: 'app1',
                        filename: 'remoteEntry.js',
                        exposes: {
                            './Button': './src/Button',
                        },
                        shared: {
                            react: { singleton: true },
                            'react-dom': { singleton: true },
                        },
                    }),
                ],
            };
            

            // main.js
            import { registerApplication, start } from 'single-spa';

            registerApplication(
                'app1',
                () => import('./app1/main.js'),
                location => location.pathname.startsWith('/app1')
            );

            start();
            

            // To create a component
            bit add src/components/Button.js --name button
            bit tag button 1.0.0
            bit export your-org.components
            

4. Best Practices

• Keep components small and focused on a single responsibility.
• Use consistent naming conventions for components across the application.
• Avoid tight coupling between micro frontends to ensure independent deployments.
• Document the contracts for shared components clearly.
• Implement robust versioning strategies for shared components.
