These are the stream modules I usually use in my projects: through2, from2, end-of-stream, pump and duplexify. Some of them handle some weird edge-cases, which would really not be that much fun to implement manually each time. Here is also a nice collection of stream utilities: https://github.com/maxogden/mississippi
because `require('stream').Through` pretty much does everything through2 does... new Transform({ objectMode: true, transform(chunk, enc, cb) {}, flush(cb) {} }); Is there something through2 inherently does that this doesn't? The internals provide... I mean, you can either inherit from the template streams, or you can use streams that actually serve a purpose.. Readable handles backpressure by default, not sure why you'd want from2 or through2 ... end-of-stream comes down to knowing when to listen for 'end' (readable/through) and 'finish' (writable). pump actually seems to serve a purpose... as does the likes of split2, and others... but the most basic readable/transform/writable bases are covered in the box, and it's really better to use them than bring in potentially a bunch of extra dependencies.
