Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including version-changed with all npm packages installed. Try it out:

var versionChanged = require("version-changed")

Node version Build Status JavaScript Style Guide

Install

$ npm i version-changed -S|-D|-g

Usage

In code:

const versionChanged = require('version-changed')
versionChanged((err, changed) => {
  if (err) throw err
  console.log('version changed', changed)
})

On command line:

$ version-changed && ./dosomething

When used in package.json it's more handy to shortcut with ||. For this reason you can use version-unchanged.

The prebuild script below will run prebuildify if the version has changed, but will not fail if the version didn't change.

{
  "scripts": {
    "prebuild": "version-unchanged || prebuildify --napi"
  }
}

API

versionChanged(err, cb)

Calls back with (err, changed) where changed is true if the version in package.json at the current commit has changed compared to the previous commit, otherwise false.

CLI

version-changed

Exits with 0 if the version has changed. Use this together with &&.

version-unchanged

Exits with 0 if the version is unchanged. Use this together with ||.

Kudos

This code was extracted from prebuild-ci. Kudos to @juliangruber. :heart:
