Version-changed NPM

version-changed

Checks if the version in package.json has changed since the last commit.

Node version

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.
