The node_modules directory is notorious for gobbling up disk space in JavaScript projects. If left unchecked, it can quickly balloon in size, consuming valuable storage. Here are seven strategies to keep it lean and free up disk space:
1. Embrace npm ci for Clean Installs:
- When setting up a project from an existing
package-lock.json, usenpm ci. It removes the existingnode_modulesand installs dependencies afresh, ensuring no lingering, unnecessary packages occupy space.
2. Prune Redundant Packages:
- Over time, you might accumulate packages that are no longer in use. After removing a package from
package.json, runnpm pruneto ensure it and its orphaned dependencies are purged fromnode_modules.
3. Limit Global Installations:
- While global installations can be convenient for CLI tools, be judicious. Only install packages globally that you use across projects to avoid multiple space-consuming installations.
4. Visualize and Audit with npm list:
- Use
npm listto get an overview of your dependencies. Spotting and removing unnecessary large packages can free up significant space.
5. Deduplicate with npm dedupe:
- Redundant or duplicated packages can bloat
node_modules. Runnpm dedupeto consolidate and reduce the directory's size by eliminating these redundancies.
6. Exclude from Version Control:
- Committing
node_modulesto version control not only bloats the repository but also your local clone. Always use a.gitignorefile to keepnode_modulesout of version control.
7. Regularly Update and Clean Cache:
- Keeping dependencies updated can sometimes reduce their size due to optimizations. Additionally, clear the npm cache periodically using
npm cache clean --forceto free up space taken by outdated or unused packages.
Conclusion:
The node_modules directory, while essential, doesn't have to be a disk space hog. By implementing these strategies, you can maintain a lean project environment, ensuring efficient use of storage and a smoother development experience.

I discovered npkill a while back and use it regularly now. Very easy to reclaim disk space. Especially for projects that you only visit infrequently.
