lwc-performance

What problem does it solve?

Unoptimized Lightning Web Components (LWCs) can suffer from excessive renders, unnecessary data fetches, heavy DOM, and slow initial load times, leading to a poor user experience.

Core Features & Use Cases

• Wire caching and selective data fetching to reduce server trips and improve responsiveness.
• Lazy loading and dynamic imports to load heavy components only when needed.
• Rendering optimizations, guarded lifecycle hooks, and efficient DOM handling to minimize work and improve perceived performance.
• Real-world use case: optimize a dashboard page with multiple LWCs displaying related data while maintaining snappy UX.

Quick Start

Start by auditing an LWC page for redundant renders and progressively apply wire caching, lazy loading, and renderedCallback guards.
