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 binary as part of your build pipeline to handle this.

$ node-prune /path/to/node_modules

In one instance, I saw a reduction from 400MB to 11MB in the node_modules directory size.
