inspectpack

Inspectpack is an inspection tool for Webpack frontend JavaScript bundles, providing detailed analysis of module sizes, duplicates, and optimization opportunities. Current stable version is 4.7.1 (released 2024). It is maintained by Formidable Labs and can be used both as a Webpack plugin (DuplicatesPlugin) and as an offline CLI tool. Key differentiators: it is the engine behind webpack-dashboard, offers actionable reports for trimming wasted bytes, and supports both plugin and CLI usage with commands like duplicates, versions, and sizes. It has TypeScript types shipped and requires Node >=6.
