tuple-stream2:将多个可读对象流对齐为一个流

元组流2 将多个对齐为一个流。 对象相等性由可选的比较器函数确定。 每个元组在内部进行缓冲，然后在每个传入流具有属性后刷新。 因此，有序流可能消耗更少的内存。 例子 var through = require ( "through2" ) var TupleStream = require ( "tuple-stream2" ) // an object map of streams, but could also be an array var stooges = { before : through . obj ( ) , after : through . obj ( ) } stooges . before . write ( { id : 1 , name : "Moe" } ) stooges . before . write ( { id : 2 , name
