Can this skill prevent large PRs from breaking performance?

Yes, it includes patterns for CI/CD integration that use performance budgets to automatically block pull requests if a bundle exceeds its defined size limit.

Is this skill compatible with Next.js?

Yes, it includes specific configurations for Next.js, including modularized imports in next.config.ts and dynamic routing optimization patterns.

How does this skill help with icon bloat?

It implements a build-time manifest generator that imports only specifically used icons instead of importing an entire library, which can reduce icon-related bundle size by up to 90%.

How do I monitor bundle size changes over time?

The skill provides a workflow for using @next/bundle-analyzer and the size-limit package to track metrics and compare them across different builds.

Does it work with Lucide Icons?

Yes, it specifically provides configuration for modularizing Lucide imports to ensure individual icons are loaded without the entire package.

分析と監視

Optimizes web application bundle sizes using strategic icon manifests, tree-shaking, and automated performance monitoring.

概要

This skill provides a comprehensive framework for reducing JavaScript bundle bloat, specifically highlighting a proven strategy that achieved a 90% reduction in bundle size. It guides developers through implementing automated icon manifests, configuring tree-shaking for libraries like Lucide, managing dynamic imports for heavy components, and enforcing performance budgets using size-limit tools. This is particularly useful for Next.js and React projects where third-party dependency growth has negatively impacted Core Web Vitals and initial load times.
