How do I split the Syncfusion bundles into individual libraries?
When developing React applications with Syncfusion UI components, performance optimization is key. One effective way to enhance performance is by splitting the Syncfusion bundles into individual libraries. This can be achieved using Webpack, and this article will guide you through the process.
Create a React App
Begin by creating a React app following the steps outlined in the Syncfusion documentation for creating a React Webpack app. This typically involves setting up a new React project, installing necessary dependencies, integrating Syncfusion components, and configuring your Webpack settings.
Install the Bundle Analyzer
To visualize the bundles using the bundle analyzer and facilitate splitting, install the Webpack bundle analyzer and the fs module. Run the following npm command in your terminal:
npm i fs webpack-bundle-analyzer --save
Configure Webpack for Splitting Bundles
In the webpack.config.js file, add the following configuration to enable splitting Syncfusion bundles into individual libraries:
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
const fs = require('fs');
const syncfusionModules = fs.readdirSync('./node_modules/@syncfusion/');
module.exports = {
// … other webpack configurations
optimization: {
splitChunks: {
cacheGroups: {
vendors: {
test: /[\\/]node_modules[\\/](?!@syncfusion[\\/])/, // exclude syncfusion packages
name: 'vendor',
chunks: 'all',
},
},
},
},
};
syncfusionModules.forEach(moduleName => {
module.exports.optimization.splitChunks.cacheGroups[moduleName] = {
test: new RegExp(`[\\\\/]node_modules[\\\\/]@syncfusion[\\\\/]${moduleName}[\\\\/]`),
name: moduleName, // Use the folder name as the bundle file name
chunks: 'all',
};
});
This configuration tells Webpack to use the splitChunks optimization to separate Syncfusion libraries from other vendor libraries. The BundleAnalyzerPlugin can be used to visualize bundle sizes and optimize large dependencies.
Build Bundles
Now run the below command to split the Syncfusion packages.
npm run build
After the build process completes, you can see the Syncfusion bundles split into individual libraries, which can lead to improved load times and overall performance of your React application.
Visualizing the Split Bundles
You can use the BundleAnalyzerPlugin to visualize the split bundles and confirm that the Syncfusion libraries are indeed separated from the main bundle.
Conclusion
By following the steps outlined above, developers can optimize their React applications by splitting Syncfusion bundles into individual libraries. This can lead to a more efficient and performant application.
