Thanks @teddy-gustiaux and @garethmcc!!
I am still somewhat confused, but now I understand that I was looking at old articles. It is unfortunate that a google search for “Serverless Websockets” brings up all the older blog posts! Possibly, someone from the Serverless team could add a callout that this guide is outdated and link to the newer ones you have provided here?
I probably should have looked through the issues, but I didn’t even bother because I figured the repo was archived so people couldn’t ask questions anyway. In my opinion that closed issue deprecation notice is nowhere near as __ as it should be. It should be front and center at the top of the README in bold letters the way it is in countless other deprecated READMEs.
If you leave the repo the way it is currently, you will most likely get simpletons like me asking questions here because they are super confused.
