How to load
@bugsnag/js using the CDN
For browser-only error reporting, we provide a hosted option on our CDN. This means you can get started with BugSnag with a simple
To load BugSnag from the CDN, add the following script tags to the
<head/> of your page:
<script src="//d2wy8f7a9ursnm.cloudfront.net/v7/bugsnag.min.js"></script> <script>Bugsnag.start('YOUR_API_KEY')</script>
The first line loads the BugSnag library from the CDN and the second configures it with your API key. You can alternatively supply a configuration object as documented in configuration options.

Automatically accepting new versions of dependencies in your software is convenient, but has tradeoffs. Whilst we make every effort to be conservative and cautious with our minor/patch releases, unforeseen issues and incompatibilities can arise.
For these reasons, the safest approach involves manually updating the version, testing it in a development/staging environment and only then shipping to production.
To use the non-minified version, substitute
bugsnag.js in your script tag.
The minified version ships with source maps, so there are very few use cases where you would want the non-minified version (for example, debugging an issue in a browser that doesn’t support source maps).
