Frontend page loading speed can be optimized through various methods. Here are some common optimization strategies:

• Reduce HTTP Requests:

  • File Consolidation: Combine multiple CSS and JavaScript files into a single file to reduce the number of requests.
  • Sprite Images: Combine multiple small icons into one image file to reduce image requests.

• Optimize Images:

  • Image Compression: Use tools like ImageOptim or TinyPNG to reduce image file sizes.
  • Choose Appropriate Image Formats: Use modern formats like WebP, which are typically smaller than JPEG or PNG.
  • Lazy Loading: Only load images within the user’s viewport to reduce initial data load.

• Use CDN:

  • Deploy static resources on CDN to reduce data transmission distance and speed up loading.

• Code Splitting:

  • Use tools like Webpack for code splitting to load resources on demand.

• Leverage Caching:

  • Utilize browser caching by setting appropriate HTTP cache headers to reduce repeated resource downloads.

• Minimize Repaints and Reflows:

  • Optimize CSS selectors to reduce complexity.
  • Avoid using complex CSS properties in DOM operations.

• Load JavaScript Asynchronously:

  • Use async or defer attributes to load JavaScript files asynchronously and avoid blocking rendering.

• Preload and Preconnect:

  • Use <link rel="preload"> to preload critical resources.
  • Use <link rel="preconnect"> to preconnect to important external domains.

• Server-Side Rendering (SSR):

  • Generate HTML on the server side to reduce client-side rendering time.

• Optimize CSS and JavaScript:

  • Remove unused code and comments.
  • Use Tree Shaking techniques to eliminate unused code.

• Implement HTTP/2:

  • Enable HTTP/2, which supports multiplexing and reduces the number of TCP connections.

• Optimize Font Loading:

  • Use the font-display property to control font loading behavior and prevent invisible text during font loading.

• Optimize Third-Party Scripts:

  • Review and optimize the use of third-party scripts to reduce unnecessary script loading.

Through these methods, you can significantly improve frontend page loading speed and enhance user experience.
