连续两个以上的流？

Question

我无法在一行中获取两个流以在node.js中工作。请参阅以下代码：

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); 

如何获得连续两个流工作？

Answer 1

你会觉得很愚蠢的，它是一个错字错误：

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

看到区别了，在stream3.writable额外e。

Answer 2

尝试async（或从nmpjs.com） - 最流行的Node.js模块，用于通过示例和wiki处理异步JavaScript。
