Recently, I got a chance to work on performance optimization for a website. I applied a mix of frontend techniques, and we were able to achieve around 20–25% improvement in overall performance. Some of the key things we worked on: • Code splitting • Converting heavy PNG images to SVG/WebP • Lazy loading components • Setting timed cache clearing • Using useCallback and useMemo wisely • Reducing unnecessary re-renders • Removing unused libraries • Asset compression and optimization • Improving API response handling • Debouncing expensive calls • Using React DevTools to identify wasted renders • Running Lighthouse and Web Vitals checks The main takeaway: Performance never comes from one single change — it’s the result of multiple optimizations working together. If I missed any performance techniques, please comment and add them — would love to learn from the community as well. #frontend #reactjs #javascript #webperformance #webdev #optimization #developers #coding #reactdeveloper
Nice list Piyush Shukla! You could also add preloading critical assets & reducing long tasks—it helps improve TTI and CLS.
Try using the Why Did You Render (WDYR) tool. Its great for catching unnecessary re-renders in React.
Hello Piyush Shukla Great list of performance optimization techniques!! I would love to add 1. Adding pagination for a large list of data sets. 2. Shifting large global state, with multiple mini-states, from Context API to external state management libraries such as react-redux, Recoil, zustand, etc
