In this episode, Lucas and Luna dive into one of the most overlooked performance bottlenecks in modern web development: JavaScript bundling. They explore how common bundler configurations—from Webpack to Vite—can inadvertently bloat your bundles, leading to slower load times and a worse user experience. Using real-world examples, they break down the concept of tree-shaking and explain why it often fails with side-effectful code. They also discuss code-splitting strategies, the pitfalls of monolithic vendor bundles, and how to audit your own bundle composition using tools like source-map-explorer. By the end, you'll have a concrete checklist to reduce your JavaScript payload by 30% or more. #JavaScript #WebDevelopment #Bundling #Webpack #Vite #Performance #TreeShaking #CodeSplitting #BundleSize #SourceMapExplorer #Technology #FexingoBusiness #BusinessPodcast #Frontend #Backend #ModernWebStack #Optimization #LoadTime Keep every episode free: buymeacoffee.com/fexingo
