Meta-package to make browsers and Node use different EventSource polyfills

npm install @sanity/eventsource

import polyfilledEventSource from '@sanity/eventsource'

The polyfill adds support for auth headers, which isn't part of the EventSource spec.

In NodeJS environments it's the implementation from eventsource package. While browsers use event-source-polyfill.

To get the browser implementation, no matter how your bundler or runtime understands package.json exports, you can use the following:

import polyfilledEventSource from '@sanity/eventsource/browser'

To force the Node implementation, use the following:

import polyfilledEventSource from '@sanity/eventsource/node'
