Trail is a minimalistic, composable framework for building HTTP/WebSocketservers, inspired byPlug & [WebSock][websock]. It provides its userswith a small set of abstractions for buildingtrails that can be assembled tohandle a request.

To create a Trail, you can use the syntaxTrail.[fn1;fn2;fn3;...], where eachfunction takes a connection object and an arbitrary context, to produce a newconnection object.

For example:

openTrailopenRouterlet endpoint=  [    use (moduleLogger)Logger.(args~level:Debug());    router      [        socket"/ws" (moduleMy_handler)();        get"/" (funconn ->Conn.send_response`OK {%b|"hello world"|} conn);        scope"/api"          [            get"/version" (funconn ->Conn.send_response`OK {%b|"none"|} conn);          ];      ];  ]
