Excluding dev dependencies from packaged npm package

[hezronkimutai]

I am working on an npm package that depends on dev dependencies. I want to package only the bundled file saved in index.js, a README file, and package.json file.
However, the "npm pack command" packs the required files plus all the dependencies that our npm package uses making the node_modules pretty heavy. Is there a way I can ignore the dev dependencies from being added to the package?
