seneca的一段代码（原创）

var seneca=require('seneca')()

seneca.add({cmd:'wordcount'},function(msg,respond){

var length=0;

if(msg.hasOwnProperty('phrase'))

length=msg.phrase.split(' ').length;

respond(null,{words:length});
});

seneca.act({cmd:'wordcount',phrase:'hello everybody! i love all of you!'},function(err,response){

if(err){

console.log('Error!');
return;
};

console.log(response);

});

seneca.act({cmd:'wordcount'},function(err,response){

if(err){

console.log(err);
return;
};

console.log(response);

});
