In this video, get an introduction to the real-time-web library Socket.io and how this could be used.
- [Instructor] Have you ever wanted to build an application…with real-time messaging…or similar real-time web applications?…Take a look at the socket.io library,…which uses an event-based approach for syncing…and transmitting data in real-time.…So go to this link, socket.io,…and once you're there,…you're actually going to see,…let me just refresh my page.…You're going to see some examples of the code…and what it actually does in your browser.…And basically socket.io is an event-based system…that actually uses events…and then subscribes to these events.…
So whenever someone,…so let's say, for example,…types a message in a chat room,…then everybody that is in that chat room…is actually noticed and updated with that information.…There are a whole bunch of demos on the website,…so if you take a look at the demo section,…you can take a look at the chat here…and actually type your name,…so in my case, manny,…and then enter,…and there's actual people in that room…and you can actually type something.…Hello.…You're live.…
Not love, but live.…
