Cauldron is a web server implemented as a library, it's easy to embed intoother applications and fairly easy to implement DSLs on it, an exampleof a DSL using cauldron isurna.

defmoduleFoodouseCauldron# respond to a GET / request with "Hello, World!"defhandle("GET",%URI{path:"/"},req)doreq|>Request.reply(200,"Hello, World!")endend# open the cauldron on port 8080Cauldron.startFoo,port:8080

Because I don't like how cowboy handles things and there are no other pureElixir webservers around that I know of.

Right now cauldron is faster than node.js and slower than cowboy, there' stillspace for speed improvements but it's not a high priority right now.

The slowness comes from protocol dispatching in Elixir, protocol consolidationwill fix that.

Also we don't use an hand-crafted decoder like cowboy does but use:erlang.decode_packet.
