Join Alex Banks for an in-depth discussion in this video Build speaker form, part of Building a Polling App with Socket IO and React.js.
- The process for joining our speaker is going to look…pretty similar to the process for joining audience members.…The main difference is that when a speaker joins,…technically they are starting the presentation…and they will need to supply the presentation's title.…So let's start by programming our listener…for a start event meaning a speaker has joined…on the server.…I'm going to go ahead and open up the app server…JS file and the first thing I need to do is add a variable…to hold information about our speaker.…So I'm going to come down here on line seven…and drop my cursor at the end of this line…and hit enter and add a speaker.…
And because there's only one speaker, we're going to create…this variable as an object as oppose to an array.…So now when a speaker joins the presentation,…we are going to call that a start.…So down here after line 16 where we wire up…all the socket listeners in the connection of a handler,…we're going to need to add a socket for starting.…So I want to scroll down here to below…the join socket listener and on line 42 I'll drop…
