@aduth/is-dependency

A utility to quickly determine if the given package(s) are dependencies within the current working directory.

This implementation optimizes speed over accuracy, synchronously returning true if the package is defined as a dependency in the current directory's package.json, regardless of whether it's actually installed.

Installation

Install using npm:

npm install @aduth/is-dependency

Usage

Pass a name or array of names of dependencies and receive a boolean value in return.

import { isDependency } from '@aduth/is-dependency';

isDependency('@aduth/is-dependency');
// true

API

isDependency

Returns true if the given package name or array of names are all defined as dependency's in the current working directory's relative package.json.

Optionally, pass an object of options to control the behavior.

export type Options = {
	/**
	 * Fields to check in `package.json`.
	 */
	fields: string[];
};

export function isDependency(
	nameOrNames: string | string[],
	options?: Partial<Options> | undefined
): boolean;
