Analyze npm dependencies to identify which ones are causing bloat and slowing down install times.
Cost of modules is a Node.js command-line tool that analyzes the size of npm dependencies in a project. It helps developers identify which packages are taking up the most space in node_modules, enabling them to optimize for faster install times and reduce bloat. The tool addresses the challenge of measuring dependency sizes in npm 3's flat installation structure.
Node.js developers and npm package maintainers who want to optimize their project's install speed and reduce dependency bloat. It's particularly useful for those publishing public packages where user experience matters.
Developers choose Cost of modules because it provides clear, actionable insights into dependency sizes that aren't easily visible with modern npm. Its focus on install speed optimization and future roadmap for pre-publish checks make it a valuable tool for maintaining efficient packages.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Displays dependencies sorted from largest to smallest, making it easy to identify bloat, as shown in the screenshot.
Optimizes for faster npm installs by targeting heavy dependencies, directly addressing setup speed as part of user experience.
Includes devDependencies with the --include-dev flag, useful for improving collaborator experience during setup.
Supports both npm and yarn via command-line flags, allowing analysis across different workflows.
The README admits future features like file size checks and historical comparisons are not yet implemented, limiting its utility as a pre-publish checklist.
Lacks APIs or plugins for integration into build processes, requiring manual execution each time analysis is needed.
Only measures disk space of node_modules, ignoring bundle size which is critical for frontend performance optimization.
