Static Site Generation Best Practices: Building High-Performance, Maintainable Modern Websites

Introduction

In modern frontend development, Static Site Generation (SSG) has become an important choice for building high-performance websites. Compared to traditional Server-Side Rendering (SSR) and Client-Side Rendering (CSR), SSG offers better performance, security, and maintainability.

This article provides a complete guide to static site generation best practices, from technology selection to performance optimization, helping you build fast, maintainable modern websites.

What is Static Site Generation?

Core Concepts

Static Site Generation is a technology that pre-renders pages at build time, generating pure static HTML files that don’t rely on server-side real-time rendering.

Advantages of SSG

• Excellent Performance: Static files load quickly, no server-side processing required
• Secure and Reliable: No server-side execution environment, reducing security risks
• Simple Deployment: Can be deployed to any static file hosting service
• SEO Friendly: Complete HTML content is beneficial for search engine indexing
• Scalable: Can easily handle high traffic

Comparison with Other Rendering Methods

Rendering Method	Advantages	Disadvantages	Suitable Scenarios
SSG	Excellent performance, secure, simple deployment	Longer build time	Websites with infrequent content changes
SSR	Real-time data, fast first screen	High server load, high cost	Websites with frequent content changes
CSR	Good development experience, rich interactions	Slow first screen load, poor SEO	Interaction-intensive applications
ISR	Combines advantages of SSG and SSR	Complex implementation, complex caching strategy	Static websites that need real-time data

  • Image compression
• Resource Compression:
  • HTML compression
  • CSS compression
  • JavaScript compression

2. Loading Optimization

• Preloading: Use <link rel="preload"> to preload critical resources
• Preconnect: Use <link rel="preconnect"> to preconnect to important domains
• Font Optimization:
  • Font subsetting
  • Font preloading
  • Reasonable font loading strategy
• CSS Optimization:
  • Critical CSS inlining
  • Avoid CSS blocking

3. Runtime Optimization

• Reduce Reflows and Repaints: Optimize DOM operations
• Use Intersection Observer: Implement efficient lazy loading
• Caching Strategy:
  • Browser caching
  • CDN caching
  • Reasonable cache invalidation strategy
• Reduce JavaScript:
  • Minimize JavaScript bundle size
  • Defer loading non-critical JavaScript
