pkg-conf

Get namespaced config from the closest package.json

Having tool specific config in package.json reduces the amount of metafiles in your repo (there are usually a lot!) and makes the config obvious compared to hidden dotfiles like .eslintrc, which can end up causing confusion. XO, for example, uses the xo namespace in package.json, and ESLint uses eslintConfig. Many more tools supports this, like AVA, Babel, nyc, etc.

Install

$ npm install pkg-conf

Usage

{
	"name": "some-package",
	"version": "1.0.0",
	"unicorn": {
		"rainbow": true
	}
}

const pkgConf = require('pkg-conf');

(async () => {
	const config = await pkgConf('unicorn');

	console.log(config.rainbow);
	//=> true
})();

API

It walks up parent directories until a package.json can be found, reads it, and returns the user specified namespace or an empty object if not found.

pkgConf(namespace, [options])

Returns a Promise for the config.

pkgConf.sync(namespace, [options])

Returns the config.

namespace

Type: string

The package.json namespace you want.

options

Type: Object

cwd

Type: string
Default: process.cwd()

Directory to start looking up for a package.json file.

defaults

Type: Object

Default config.

skipOnFalse

Type: boolean
Default: false

Skip package.json files that have the namespaced config explicitly set to false.

Continues searching upwards until the next package.json file is reached. This can be useful when you need to support the ability for users to have nested package.json files, but only read from the root one, like in the case of electron-builder where you have one package.json file for the app and one top-level for development.

Example usage for the user:

{
	"name": "some-package",
	"version": "1.0.0",
	"unicorn": false
}

pkgConf.filepath(config)

Pass in the config returned from any of the above methods.

Returns the filepath to the package.json file or null when not found.

read-pkg-up - Read the closest package.json file
read-pkg - Read a package.json file
find-up - Find a file by walking up parent directories
