Socket.io alternative [closed]
A few days ago Socket.io 1.0 was released (previous version was 0.9). The official website http://socket.io seems to being updated too (as well as Socket.io's Github wiki page). I visited a new version of the website just yesterday and it was 200 OK.
As for your question - well, this is really opinion-based, and in my opinion Socket.io provides all you need to build cross-browser real-time applications, so I would recommend using it. Socket.io is good because:
- It has a variety of transports between client and server: WebSockets, XHR long polling, JSONP, Flashsockets, etc. (Important note: since version 1.0 Socket.io is able to change transport on a fly without messages loss)
- It has rooms support
- It has auto-reconnect support
- It has simple and convenient API
- It has simple integration with Express and Koa
- It has large community
- It is fully cross-browser
Though if you want to know more about alternatives, take a look at SockJS. This is a framework similar to Socket.io. But since I have never used it I can't tell how good it is.
Good luck and sorry for my English :)
