Frontend performance optimization is a topic every developer should care about. Good performance not only improves user experience but also significantly boosts conversion rates.
Performance Metrics
First, we need to understand core performance metrics, including First Contentful Paint (FCP), Largest Contentful Paint (LCP), and Cumulative Layout Shift (CLS).
The first step in performance optimization is establishing a measurement system. Without measurement, there’s no optimization.
Optimization Strategies
Common strategies include code splitting, lazy loading, caching strategies, and image optimization. The key is choosing the right approach for your specific scenario.
In practice, performance optimization is an ongoing iterative process that requires continuous monitoring and improvement.
