Optimizing frontend applications requires careful attention to performance bottlenecks. Let’s dive into a few strategies for making sure your app is fast and efficient.
Reduce bundle sizes by minifying CSS and JavaScript. Consider tree-shaking to eliminate unused code. Smaller files mean fewer bytes over the wire and quicker load times.
Leverage browser and CDN caching to avoid redundant requests. Use Cache-Control headers to define caching policies. For static assets, implement long-term caching with hashed filenames to ensure cache validity when content updates.
Defer loading non-critical images until they enter the viewport. Use the loading="lazy" attribute on tags to improve initial page speed and reduce blocking. For more advanced cases, consider Intersection Observer API for custom control.
Minimize the number of requests with batching or use GraphQL to query exactly what you need. Enable compression like Gzip or Brotli for responses. Use HTTP/2 multiplexing for parallel requests to reduce latency.
Combining these strategies helps achieve significant performance gains.
