Performance Optimization

Apply these performance optimization principles when developing web applications, themes, and frontend interfaces.

Core Performance Principles

• Prioritize server-side rendering as a first principle, as opposed to client-side JavaScript
• Minimize client-side JavaScript to reduce bundle size and improve Time to Interactive
• Optimize for Core Web Vitals: LCP, FID, and CLS
• Measure performance continuously and establish baselines
• Consider performance impact of every architectural decision

Server-Side Rendering

• Render content server-side whenever possible
• Use streaming rendering for faster Time to First Byte
• Implement proper caching strategies for rendered content
• Avoid blocking resources that delay rendering
• Pre-render static content where applicable
