XMLHttpRequest is not defined in Netlify Functions

Issue Summary

XMLHttpRequest is not defined in Netlify Functions

To Reproduce

1. Try to fetch content via Content API JS SDK in netlify function

I think @tryghost/content-api uses axios to send AJAX requests. Axios depends heavily on XMLHttpRequest for its functioning.

Possible alternatives can be https://github.com/developit/redaxios

Technical details:

• Ghost Version: 3.41.4
• Node Version: 12.20.1
• Browser/OS: Irrelevant
• Database: mysql

Looks like the issue is linked to browser: true rollup config option. This will result in axios dependency to be built based on assumption it is used in the browser only - with xhr always used as the adaptor

I have the same issue with ElectronJS. On the main (nodejs) thread. And axios is a dependency of the project.

Any idea?

You can maybe alias the axios module imports to redaxios in your bundler.

For my project, I changed the way I was using the content API to only run on the browser.
