Consistent update notifications for packages

Usage no npm install needed!

<script type="module">
  import zeitCheckUpdates from 'https://cdn.skypack.dev/@zeit/check-updates';



This package makes it very easy to implement update notifications into ZEIT packages:

Firstly, install the package:

npm install @zeit/check-updates

Next, initialize it:

const pkg = require('./package')
const updateNotifier = require('@zeit/check-updates')

updateNotifier(pkg, 'Project Name')

You can even pass a millisecond interval for the cache (a day by default):

updateNotifier(pkg, 'Project Name', 80000)


  1. Fork this repository to your own GitHub account and then clone it to your local device
  2. Link the package to the global module directory: npm link
  3. Within the module you want to test your local development instance of the package, just link it: npm link @zeit/check-updates. Instead of the default one from npm, node will now use your clone.
