You can specify the Notifier API key for the project, the minified URL, and the source map file and it will be uploaded to our servers. We will then use that uploaded source map file whenever we receive an error event from that URL. You can also specify which version of your app the file applies to and upload the associated source files if required. You can learn more about this in the Bugsnag’ documentation.
Why would I upload source maps instead of hosting them myself?

It also means that we won’t need to go to your servers to fetch the files every time an error is received (reducing the load on your servers).
In the case you do want to host them yourself, we still support fetching the source maps on the fly if you include the
