SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Dynamic import reduces the initial JavaScript payload by loading non-essential modules on demand, speeding initial render and improving perceived performance.

Core Features & Use Cases

  • Lazy-load components with React.lazy or import() to split code into smaller bundles.
  • Use Suspense to provide fallback UI while modules load.
  • Evaluate and identify which components to defer based on user interactions to optimize startup time.

Quick Start

Demonstrate lazy loading of a non-critical component using dynamic import() to shrink the initial bundle.

Frequently Asked Questions about dynamic-import

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I lazy load non-critical React components to speed up startup?▼

Lazy loading non-critical React components speeds startup by using React.lazy and dynamic import() to split code into smaller bundles. This reduces the initial JavaScript payload and shifts loading to user interaction.

What's the best way to provide fallback UI while lazy loading modules?▼

Provide fallback UI during lazy loading by wrapping dynamic import() components in React Suspense. Suspense renders placeholder content while the deferred module loads, improving perceived performance.

Can I use dynamic import for code splitting with server-side rendering (SSR)?▼

Dynamic import supports SSR considerations by evaluating dependency boundaries to prevent unintended loads. It analyzes module boundaries to ensure lazy loading integrates safely with server-side rendering workflows.

How does code splitting with dynamic import reduce initial bundle size?▼

Code splitting via dynamic import reduces initial bundle size by loading non-essential modules on demand. This defers non-critical JavaScript payloads until specific features require execution.

When should I not use lazy loading for JavaScript modules?▼

Avoid lazy loading for critical modules needed immediately on startup. If deferred loading causes unintended dependency loads or delays essential user interactions, keep those modules in the initial bundle.
