How to combine multiple transform streams into one in nodejs
I have the following piece of code
function func1(){
return makeReadbleStream1()
.pipe(transformA)
.pipe(transformB)
.pipe(transformC)
.pipe(X);
}
function func2(){
return makeReadbleStream2()
.pipe(transformA)
.pipe(transformB)
.pipe(transformC)
.pipe(Y);
}
Function 1 and 2 share common logic for passing transforms A, B, and C. Based on the DRY principle, I find it better to extract the logic into mixedTransformABC function. However, it doesn't seem to me an obvious way to implement this function based on transformA, B, and C so that I can refactor the code like below.
function func1(){
return makeReadbleStream1()
.pipe(combinedTranformABC)
.pipe(X);
}
function func2(){
return makeReadbleStream2()
.pipe(combinedTranformABC)
.pipe(Y);
}
Any idea?
