npm-install-package-info

This Node module returns the name and version of an NPM package of any source npm install can handle (including Git-Host, Github, Tarball files/URLs, scoped packages etc.). It synchronously performs a dry-run of npm install and grabs the info from stdout.

Install

npm install --save npm-install-package-info

Usage

const packageInfo = require('npm-install-package-info')

packageInfo('debug') // { name: 'debug', version: '4.1.1' }
packageInfo('debug@^2') // { name: 'debug', version: '2.6.9' }
packageInfo('github:jvolker/Openframe-Processing') // { name: 'openframe-processing', version: '0.2.0' }
packageInfo('/Users/Erik/Documents/MyProject') // accordingly

On error

Returns null on error. For example if the package can't be found.

Suppress error messages

To disable error messages there is a second optional parameter:

packageInfo('/Users/Erik/Documents/MyProject', true)

Tested

Manually tested with the following NPM versions:

• 6.9.0
• 5.6.0
• 3.10.10

Why?

npm view doesn't support the same amount of sources.
