React Bundle Optimizer

A comprehensive toolkit for optimizing React application bundles. This package provides tools and utilities to reduce bundle size, improve loading performance, and identify optimization opportunities.

Features

- 🔍 Bundle Analysis: Identify large chunks, unused code, and duplicate dependencies
- ⚡ Import Optimization: Transform and optimize React imports
- 🚀 Code Splitting: Automatic detection and configuration of code splitting opportunities
- 🧩 Component Optimization: Tools for optimizing React components and hooks
- 📊 Performance Reports: Generate detailed bundle analysis reports

Installation

``bash
npm install react-bundle-optimizer

or

yarn add react-bundle-optimizer
`

Usage

$3

Add the Babel plugin to your .babelrc or babel.config.js:

`javascript
{
"plugins": [
["react-bundle-optimizer/babel", {
"optimizeImports": true,
"optimizeHooks": true,
"detectLazyLoad": true
}]
]
}
`

$3

Add the Webpack plugin to your webpack.config.js:

`javascript
const { ReactBundleOptimizerPlugin } = require('react-bundle-optimizer');

module.exports = {
// ... other config
plugins: [
new ReactBundleOptimizerPlugin({
analyze: true,
splitChunks: true,
removeUnused: true
})
]
};
`

$3

Use the BundleAnalyzer to generate reports:

`javascript
const { BundleAnalyzer } = require('react-bundle-optimizer');

const analyzer = new BundleAnalyzer(webpackStats);
const analysis = analyzer.analyze();
const report = analyzer.generateReport();
`

$3

Use the provided helper functions for component optimization:

`javascript
import { optimizedMemo, lazyWithPreload } from 'react-bundle-optimizer';

// Optimize a component with memo
const OptimizedComponent = optimizedMemo(MyComponent);

// Lazy load with preload capability
const LazyComponent = lazyWithPreload(() => import('./HeavyComponent'));
``
