How to find length of a stream in NodeJS?

I have a function call uploadStream(compressedStream) in my code where I am passing compressedStream as a parameter to the function but before that I need to determine the length of the compressedStream. Does anyone know how can I do that in NodeJS?

Answer

you can get length by getting stream chunks length on the “data” event

compressedStream.on('data', (chunk) => {
   console.log('Got %d characters of string data:', chunk.length);
});
