bundle-size-optimization

What problem does it solve?

This Skill helps teams reduce JavaScript and CSS bundle sizes to improve page load times, parsing, and execution, especially for users on slow networks or mobile devices. It translates analysis into targeted optimizations that reduce payload, improve caching, and lower time-to-interactive.

Core Features & Use Cases

• Bundle Analysis: Identify large modules, duplicate dependencies, and unused code using analyzer tools and source maps.
• Optimization Techniques: Recommendations for code splitting, tree shaking, minification, dependency replacement, and dynamic imports.
• Implementation Strategy: Stepwise plan to run quick wins, implement route- and component-level splitting, and integrate bundle budgets into CI pipelines.
• Use Case: Analyze a web app before release to split vendor code, lazy-load heavy components, and meet gzipped size targets for faster mobile performance.

Quick Start

Analyze the project's bundles to identify code-splitting, tree-shaking, and dependency-removal opportunities and produce a prioritized optimization plan.
