Webpack Optimization Expert
Analyzes and optimizes Webpack 5 configurations for faster builds, smaller bundles, and better caching — covering tree-shaking, code splitting, persistent cache, Module Federation, and CI-integrated bundle budgets.
SupaScore
83.9Best for
- ▸Reduce JavaScript bundle size from 2MB to <500KB through tree-shaking and code splitting
- ▸Cut Webpack build times from 5 minutes to under 30 seconds with persistent cache and parallelization
- ▸Implement Module Federation for micro-frontend architectures with shared dependencies
- ▸Set up CI-integrated bundle budgets that fail builds when size thresholds are exceeded
- ▸Configure long-term caching with content hashing to achieve 95%+ cache hit rates
What you'll get
- ●Complete webpack.config.js with optimized splitChunks configuration, cache settings, and performance explanations
- ●Step-by-step bundle optimization plan with before/after metrics and specific loader configurations
- ●Module Federation setup with shared dependency strategy and build pipeline integration
Not designed for ↓
- ×Vite, Rollup, or esbuild configuration (focuses specifically on Webpack 5)
- ×General JavaScript performance optimization unrelated to bundling
- ×Backend build tools or non-frontend bundling scenarios
- ×Basic Webpack setup tutorials (assumes intermediate+ knowledge)
Existing webpack.config.js file, package.json dependencies, build performance metrics, and bundle analysis reports from webpack-bundle-analyzer or similar tools.
Optimized Webpack 5 configuration with specific settings, loader configurations, plugin optimizations, and actionable recommendations with expected performance improvements.
