In this guide, we&#8217;ll explore the key strategies for building lightning-fast web applications.<\/p>\n<h2>Core Web Vitals<\/h2>\n<p>Google&#8217;s Core Web Vitals have become the standard for measuring web performance. Focus on these three metrics:<\/p>\n<ul>\n<li><strong>LCP (Largest Contentful Paint)<\/strong> &#8211; Should be under 2.5 seconds<\/li>\n<li><strong>FID (First Input Delay)<\/strong> &#8211; Should be under 100 milliseconds<\/li>\n<li><strong>CLS (Cumulative Layout Shift)<\/strong> &#8211; Should be under 0.1<\/li>\n<\/ul>\n<h2>Optimization Strategies<\/h2>\n<h3>1. Minimize JavaScript<\/h3>\n<p>Every kilobyte of JavaScript you send to the browser needs to be parsed and executed. Use code splitting, tree shaking, and consider whether you really need that npm package.<\/p>\n<pre><code class=\"language-javascript\">\/\/ Instead of importing everything\nimport _ from 'lodash';\n\n\/\/ Import only what you need\nimport debounce from 'lodash\/debounce';\n<\/code><\/pre>\n<h3>2. Optimize Images<\/h3>\n<p>Images often account for most of a page&#8217;s weight. Use modern formats like WebP and AVIF, implement lazy loading, and serve appropriately sized images.<\/p>\n<h3>3. Leverage Caching<\/h3>\n<p>Implement proper cache headers, use service workers for offline support, and consider edge caching for global performance.<\/p>\n<h2>Conclusion<\/h2>\n<p>Performance optimization is an ongoing process. Measure, optimize, and iterate.
