The backend not only provides a simple REST API, but it also provides WebRTC signaling and a real-time graphical communications and presence protocol.&lt;p&gt;Haskell makes it so easy to write correct concurrent code it&amp;#x27;s not even funny. GHC&amp;#x27;s magnificent IO manager means I can handle 1000s of connections on one amazon instance. Can&amp;#x27;t understand why you wouldn&amp;#x27;t be using Haskell for server-side web development.&lt;p&gt;No other popular server-side language supports concurrency (see STM, MVar&amp;#x27;s, and Chans), transparent futures&amp;#x2F;promises for I&amp;#x2F;O (the entire IO monad in GHC is non-blocking), support for multiple processors (Just add +RTS -N&amp;lt;n&amp;gt; to make your program scale to n processors), and a blazing fast HTTP server (warp).</text><parent_chain><item><author>dexwiz</author><text>Can someone explain to me why Haskell will ever be viable as  a fullstack language? I have done a few toy projects in Haskell, and it has taught me some great functional programming concepts that I now apply to other languages.

Full Stack would be app server up. So runs a server (some sort of process&amp;#x2F;thread&amp;#x2F;worker management), server scripting is in the same language (can auth, process requests, interact with a DB, etc), and build the view (simple JSON&amp;#x2F;blob response, build html, etc). I exclude client side form this, since most of the X for client-side projects end up transpiling into JS.</text></item></parent_chain></comment><story><title>State of the Haskell Ecosystem – February 2016</title><url>http://www.haskellforall.com/2016/02/state-of-haskell-ecosystem-february.html?m=1</url></story>
