Using fetch with server-sent events 

In this video, we'll use Microsoft's fetch-event-source package to use fetch to listen for our own server-sent events generated by our very own Node.js Express server. Using fetch allows us to add a payload to our request, use HTTP methods like POST, PUT, and DELETE, and include headers for authentication and authorization purposes. This is super useful for things ranging from displaying real-time data that changes frequently (think stock ticker) all the way to streaming those ChatGPT responses :)
