I'm gonna write a tutorial, too. It will be on the subject of how to build a house using only a plot of land, a blueprint, and the services of Smithco General Contracting.
If it had been posted to Hacker News with a title like "Getting Started With CometChat and Vue," it would have been more clear. Posted to Hacker News under the title "Build a Vue Chat App" made me think it contained instructions on how one might build a chat app or perhaps a war story about someone who tried to build a chat app on Vue but ran into some interesting technical problems.
The tutorial itself actually looks pretty good. I appreciate the GitHub repo with clear "how to run this" instructions at the top and big, explanatory screenshots underneath.
