10 Ways to Reduce Bundle Size in React JS & Improve Performance

Is your React app slow, heavy, or taking too long to load?
In this video, we break down 10 practical ways to reduce bundle size in a React JS application and significantly improve frontend performance.

You’ll learn how modern React apps optimize JavaScript bundles using code splitting, route-based lazy loading, tree shaking, dependency optimization, and production builds. These techniques help reduce JavaScript payload size, speed up initial page load, and improve real-world performance metrics like First Contentful Paint (FCP) and Largest Contentful Paint (LCP).

This video is perfect for frontend developers, React developers, and web developers who want to build faster, production-ready React applications without over-engineering.

What You’ll Learn:
How React bundle size affects performance
Code splitting and lazy loading in React
Route-based lazy loading with React Router
Tree shaking and ES module best practices
How unused dependencies increase bundle size
