licensewatch v2.0.1

LicenseWatch

What is this?

This module reads the node_modules directory of a given path and fetches all licenses from reading each module's package.json and aggregates their counts into a hashmap object of licenses.

Implementation

Current implementation is with an Observable pattern so consumers need to add listeners to events the module emits.

Previous version of this module includes a Promises-based implementation and complete code coverage.

Installation

yarn add licensewatch

Usage

const LicenseWatch = require('licensewatch')
const licenses = new LicenseWatch('node_modules/**/package.json')

licenses.fetch()
let licensesCount = 0

licenses.on('files', (files) => {
  console.log('files processed' + ' - ' + files.length + ' - ' + files[0])
})

licenses.on('license', () => {
  licensesCount++
})

licenses.on('licenses', (licenses) => {
  console.log(licenses.length)
})

licenses.on('licensesSummary', (licenses) => {
  console.log(licenses)
})

licenses.on('error', (error) => {
  console.log('errors mate, from down under')
  console.log(error)
})
