Retrieves the (flat) list of package dependencies from the package manager lock file.
Currently, we support these package managers:

• npm using (NpmExtractor).

First, install the library with:

npm i @h4ad/dependency-extractor

Then, you need to read and parse the package-lock.json:

import { NpmExtractor } from '@h4ad/dependency-extractor';
import { readFileSync } from 'fs';

const extractor = new NpmExtractor();
const packageLock = readFileSync('package-lock.json').toString('utf-8');

const dependencyContainer = extractor.parse(packageLock);

Then, you can use the information collected from your dependencies with:

const allDependencies = dependencyContainer.getAllDependencies();
const productionDependencies = dependencyContainer.getProductionDependencies();
const developmentDependencies = dependencyContainer.getDevelopmentDependencies();
const peerDependencies = dependencyContainer.getPeerDependencies();
const optionalDependencies = dependencyContainer.getOptionalDependencies();

const firstDependency = allDependencies[0];

console.log(firstDependency.name);
console.log(firstDependency.version);
console.log(firstDependency.isProduction);
console.log(firstDependency.isDevelopment);
console.log(firstDependency.isOptional);
console.log(firstDependency.isPeer);

This library was based on npm-dependencies-extractor.
