Giancarlo Gomez talks about “Brief Introduction To Websockets” in this episode of ColdFusion Alive Podcast, with host Michaela Light.
Giancarlo is one of the speakers for the upcoming Into The Box ColdFusion Conference, where he will talk about WebSockets in CFML.
In his ITB talk, he plans to get into some CF Websockets code. Reviews a couple of concept apps and how to build them using WebSockets. Creates a live dashboard, a collaborating form, a little game and maybe the good old chat. Discuss some tips and tricks to help keep them up and running thru several failure points.
“With WebSockets, when the client connects, it creates a bi-directional connection that the server not only knows that the client is there, but the client also knows that the server is connected and he can send data back and forth. Now when something triggers on the server, through that connection, that message can be sent in real time to not only one, but multiple connected clients that are set to receive that data.” – Giancarlo Gomez

Interview transcript
Michaela Light: Welcome back to the show. I'm here with Giancarlo Gomez- I think I'm pronouncing your name right there? Also he's known as JC, which is a lot easier to pronounce. And he is the co-manager of the South Florida ColdFusion Users Group, which actually is now a virtual user group. Anyone in the world can join in there; it's through Meetup. And he is not only a dad and a husband, but … Web developer, musician, he owns Fuse Developments, and he created CrossTrackr, in case you do CrossFit and want to track how well you're doing. So welcome, JC.
Giancarlo G: Hello, Michael, thank you. Thank you for having me.
Michaela Light: So I know you're speaking at the upcoming Into The Box Conference and you're talking about WebSockets and … Tell us a bit about that. First of all, maybe we'd better back up a bit. What the heck is a “WebSocket,” in case people have never used it? I mean, I know it's been in ColdFusion for a few versions now, but that doesn't mean people even know it exists.
Giancarlo G: A WebSocket is the ability to send real-time information back and forth between the server and the connected client, with very little to almost no lag. Rather than the user having to poll the server or look for information from the server, the server immediately, once it knows it has information that it can send to subscribed clients, it will do it in real time.
