連續兩個以上的流？

Question

我無法在一行中獲取兩個流以在node.js中工作。請參閱以下代碼：

var Stream = require('stream'); 

var stream1 = new Stream; 
stream1.readable = true; 

var stream2 = new Stream; 
stream2.readable = stream2.writable = true; 

var stream3 = new Stream; 
stream3.readable = stream3.writeable = true; 

var i = 0; 

stream2.write = function(data){this.emit('data', data)}; 
stream3.write = function(data){this.emit('data', data)}; 

setInterval((function() { 
stream1.emit('data', String(i++)); 
}), 100); 

//works: 
stream1.pipe(stream2).pipe(process.stdout); 

//does not work - why??? 
//stream1.pipe(stream2).pipe(stream3).pipe(process.stdout); 

如何獲得連續兩個流工作？

Answer 1

你會覺得很愚蠢的，它是一個錯字錯誤：

stream2.readable = stream2.writable = true; 
stream3.readable = stream3.writeable = true; 

看到區別了，在stream3.writable額外e。

Answer 2

嘗試async（或從nmpjs.com） - 最流行的Node.js模塊，用於通過示例和wiki處理異步JavaScript。
