What does "bundle" mean in programming?
bundle is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A single file (or small set of files) that combines many JavaScript modules into one, so the browser makes fewer network requests. Bundlers (webpack, Vite, esbuild) analyze import statements, combine files, and apply optimizations like tree shaking (removing unused code) and code splitting.
Example
"The production bundle is 240KB gzipped. We need to analyze it and split the vendor libraries into a separate chunk."
