package.json is primarily for declaring an npm package and describing how it can be consumed.
However, it can often get bloated with development concerns such as devDependencies and configuration like eslintConfig, prettier, lint-staged, simple-git-hooks, etc.
Use clean-pkg-json in a prepublish hook to remove unnecessary properties from package.json. Useful in micropackages where every byte matters.
npm install --save-dev clean-pkg-json
Add clean-pkg-json to the prepack hook, which runs before npm publish and npm pack.
// package.json
{
"name": "my-package",
// ...
"scripts": {
// ...
"prepack": "clean-pkg-json"
}
