Join Alex Banks for an in-depth discussion in this video Emitting a join event, part of Building a Polling App with Socket IO and React.js.
- So once we have collected the audience member's name,…we're going to need to send it back to the server.…We're going to do this by emitting a join event…on the socket and passing the audience member's name…all the way back to the server.…So we're going to be using several files to do this.…I'm going to start by opening up our app-server.…So this is the file that we should…eventually collect the user's name in.…Now all data that communicates between the client…and the server actually goes through our app-component.…So I'm going to go down to our components…and open up the app.…So this is where we wire up the listeners…for any events that socket io is going to throw,…and we're also going to add an emit function to this…so that we can send data back to the server.…
Now we're concerned with the audience now,…so in the app we have a RouteHandler,…and that RouteHandler is specifically going to be…our Audience component right now.…So the Audience component also uses this join form…here on line 11,…and this is where all of the magic starts.…
