# clean-pkg-json
Script to remove unnecessary properties from `package.json` on prepublish hook.

## Why?
`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`](https://eslint.org/docs/latest/user-guide/configuring/), [`prettier`](https://prettier.io/docs/en/configuration.html), [`lint-staged`](https://github.com/okonet/lint-staged), [`simple-git-hooks`](https://github.com/toplenboren/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.
## Install
```
npm install --save-dev clean-pkg-json
```
## Usage
Add `clean-pkg-json` to the [`prepack` hook](https://docs.npmjs.com/cli/v8/using-npm/scripts#:~:text=on%20npm%20publish.-,prepack,-Runs%20BEFORE%20a), which runs before `npm publish` and `npm pack`.
```json5
// package.json
{
"name": "my-package",
// ...
"scripts": {
// ...
"prepack": "clean-pkg-json"
}
}
```
