# Prune The Excess From node_modules The `node_modules` directory, which is part of every JavaScript project, is infamously heavy. It is a massive directory of all your project's dependencies and those dependencies' dependencies. The size of `node_modules` can become a problem on CI build servers with limited disk space. You can significantly reduce the size of `node_modules` by pruning away all the excess files that aren't needed during builds like markdown files, typescript source files, etc. Include the [`node-prune`](https://github.com/tj/node-prune) binary as part of your build pipeline to handle this. ```bash $ node-prune /path/to/node_modules ``` In one instance, I saw a reduction from 400MB to 11MB in the `node_modules` directory size.
