We are going to talk about https://www.asp.net/signalr which is an offering through Microsoft. 1:09 – Guest: It started in 2011 that’s when I got involved, but I wasn’t with Microsoft, yet, at that point. I was working on the technology, though. Effectively you can do real time HTMP but what they did (Damon and David) let’s create a series of abstractions but not we have for Java. They basically cam up this idea let’s do web sockets and then go back to pole / pole / pole. It’s to see what the server and the client can support. Guest talks about https://socket.io, too. 6:45 – Chuck: What we are talking about real time coordination between apps. 6:56 – Guest: Web sockets, 1 million...and 2.6 million messages a second! 7:05 – Chuck: I can set that up like I usually set up web sockets? 7:17 – Guest: There is a client library for each. Effectively you have a concept called a connection. 9:48 – Chuck: How do you handle authentication on the frontend? 9:56 – Guest: We have server side things that we can attribute things. 10:09 – Chuck. 10:12 – Guest: If you authenticate to the site then the site passes the token and it basically sits on top of the same plumbing. 10:38 – Chuck. 10:42 – Guest. 10:54 – Chuck. 10:58 – Guest: We recently just had the https://www.dotnetconf.net. We had an all night, 24-hour thing. 11:48 – Chuck: Here you are, here you go. You hook it all up, JavaScript into your bundle. 12:05 – (The guest talks about how to install.) 13:12 – Chuck: I could come up with my own scheme. 13:25 – Guest: The traditional example is SEND A MESSAGE and then pass you string. Well tomorrow I do that and I just change the code – it’s great b/c I send up a ping and everybody knows what to do what that ping. It’s just a proxy. 14:17 – Chuck: I am trying to envision what you would use this for? If you are worried about it being stale then you refresh. But if you want the collaborative stuff at what point do you ask: Do I need SignalR? 15:00 – Guest: When I do my presentations on SignalR and being transparent I want to send you 1,000 messages but 1 or 2 messages will be dropped. You don’t want to transmit your order data or credit card information. Do you have a hammer and you need a screw?  If you need stock tickers and other applications SignalR would work. Keeping your UI fresh it is a great thing. 19:02 – Chuck: You do that at the Hub? You set up the Hub and it passes everything back and forth. What can you do at the Hub for filtering and/or certain types of events? 19:26 – Guest: I am looking at a slide. What’s the cool thing about SignalR and the API is it’s deceptively simple on purpose. If you want to call out to clients, you can get a message to all of your clients if you select that/those feature(s).  Some other features you have are OTHERS, and Clients.Group. 20:57 – Chuck: Can you set up your own? 20:58 – Guest: I don’t know. 21:12 – Chuck: Clients who belong to more than one group. 21:23 – Guest: Dynamics still give some people heartburn.
