@sealsystems/countingstream counts the stream length in bytes.
$ npm install @sealsystems/countingstream
First you need to add a reference to @sealsystems/countingstream within your application.
const CountingStream = require('@sealsystems/countingstream');
Then, call the constructor function.
const countingstream = new CountingStream();
CountingStream is derived from the Transform stream and can be used like any such stream. To get the number of bytes piped through, call:
const numberOfStreamedBytes = countingstream.getCount(); // -> returns the number of bytes streamed so far
You can reset the counter any time.
It is also possible to set the counter to an arbitrary value.
countingstream.resetCount(42); countingstream.getCount(); // -> returns 42
