Unleashing the Power of Web Components in React Native Expo using Module Federation

Are you tired of building identical components for both web and mobile applications? Do you want to take advantage of the power of web components in your React Native Expo project? Look no further! In this article, we’ll explore the wonders of using web components in React Native Expo using module federation, and how you can effortlessly share code between your web and mobile applications.

What are Web Components?

Web components are a set of web technologies that allow you to create custom HTML elements that can be reused across different projects and platforms. They consist of three main parts:

• <template>: defines the markup structure of the component
• <script>: defines the behavior and logic of the component
• <style>: defines the visual styling of the component

By using web components, you can create a library of reusable UI elements that can be easily shared across different projects and platforms.

What is Module Federation?

Module federation is a technique that allows you to share code between different projects and platforms by importing and exporting modules. In the context of React Native Expo, module federation enables you to share web components between your web and mobile applications.

By using module federation, you can:

• Share code between web and mobile applications
• Reuse web components in your React Native Expo project
• Reduce code duplication and improve maintainability

Setting up Module Federation in React Native Expo

To set up module federation in React Native Expo, you’ll need to follow these steps:

1. Create a new React Native Expo project using the following command:

   expo init my-app

2. Install the required dependencies, including webpack and webpack-merge, using the following command:

   npm install webpack webpack-merge

3. Create a new file called webpack.config.js in the root of your project, and add the following code:

         module.exports = {
           mode: 'development',
           devtool: 'inline-source-map',
           module: {
             rules: [
               {
                 test: /\.js$/,
                 exclude: /node_modules/,
                 use: {
                   loader: 'babel-loader',
                   options: {
                     presets: ['@babel/preset-react']
                   }
                 }
               }
             ]
           }
         };
       

4. Create a new file called federated.module.js in the root of your project, and add the following code:

         import { createFederatedModule } from 'webpack/federated';
   
         export default createFederatedModule({
           name: 'my-app',
           library: {
             type: 'var',
             name: '_myApp'
           },
           filename: 'my-app.js',
           exposes: {
             './Button': './src/components/Button'
           }
         });
       

Creating a Web Component

Now that we’ve set up module federation, let’s create a simple web component that we can share between our web and mobile applications.

Create a new file called Button.js in the src/components directory, and add the following code:

import { html, LitElement, property, customElement } from 'lit-element';

@customElement('my-button')
class Button extends LitElement {
  @property({ type: String }) label = '';

  render() {
    return html`
      <button>
        ${this.label}
      </button>
    `;
  }
}

export default Button;

This code defines a simple web component called my-button that takes a label property and renders a button element.

Using the Web Component in React Native Expo

Now that we’ve created our web component, let’s use it in our React Native Expo project.

Create a new file called App.js in the root of your project, and add the following code:

import React from 'react';
import { View, StatusBar } from 'react-native';
import { Button } from './src/components';

const App = () => {
  return (
    <View>
      <StatusBar barStyle="dark-content" />
      <Button label="Click me!" />
    </View>
  );
};

export default App;

This code imports the Button web component and uses it in the App component.

Running the Application

To run the application, navigate to the root of your project and execute the following command:

npx expo start

This will start the Expo development server, and you can view the application in your web browser by navigating to http://localhost:19006.
