Bundle Analysis - CI/CD Glossary Definition

Bundle analysis breaks down which modules make up your bundle so you can find and trim the heavy ones.

Bundle analysis is inspecting a build output to see which modules contribute to size, usually via a report or interactive visualization. Tools include webpack-bundle-analyzer and rollup-plugin-visualizer.

Analysis reads the stats a bundler emits and attributes bytes to individual modules, often as a tree map. It reveals accidental large dependencies or duplicated packages. In CI, you can generate a report artifact and gate on bundle size budgets.
