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 at the upcoming Into The Box ColdFusion Conference, where he will discuss 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 through 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 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.

Bio
Giancarlo Gomez
Giancarlo Gomez is a full-stack developer with over 17 years of experience in various languages and technologies, and a passion for continuous learning. He has been a designer, developer, and project lead for several companies stateside. He can say that this path took him across the pond years ago for a piece of software he wrote that required installation and configuration. The internet was much slower back then, and a flight was needed. He is the owner/lead developer of Fuse Developments, Inc., established in 2004, a consulting business specializing in web and mobile development. Additionally, he is the founder of CrossTrackr, Inc., a SaaS platform for the CrossFit community, targeting athletes and gym owners, which provides real-time insight into athletic progress and health metrics.

Interview transcript
Michaela Light: Welcome back to the show. I'm here with Giancarlo Gomez. I think I'm pronouncing your name correctly. Additionally, he's known as JC, which is much easier to pronounce. He is also the co-manager of the South Florida ColdFusion Users Group, which has transitioned to 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 also a web developer, musician, and owner of Fuse Developments. He created CrossTrackr, which is perfect for those who do CrossFit and want to track their progress. 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, perhaps we should 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 are even aware of it.
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 it, the server immediately sends the information to subscribed clients once it knows it has the data to share, in real-time.
Michaela Light is the host of the CF Alive Podcast and has interviewed more than 100 ColdFusion experts. In each interview, she asks "What Would It Take to make CF more alive this year?" The answers still inspire her to continue to write and interview new speakers.
Michaela has been programming in ColdFusion for more than 20 years. She founded TeraTech in 1989. The company specializes in ColdFusion application development, security and optimization. She has also founded the CFUnited Conference and runs the annual State of the CF Union Survey.
