A very minimal implementation of a PassThrough stream It's very fast for objects, strings, and buffers. Supports pipe()ing (including multi-pipe() and backpressure transmission), buffering data until either a data event handler or pipe() is added (so you don't lose the first chunk), and most other cases where PassThrough is a good idea. There is a read() method, but it's much more efficient to consume data from this stream via 'data' events or by calling pipe() into some other stream. Calling read() requires the buffer to be flattened in some cases, which requires copying memory. If you set objectMode: true in the options, then whatever is written will be emitted. Otherwise, it'll do a minimal amount of Buffer copying to ensure proper Streams semantics when read(n) is called. objectMode can only be set at instantiation. Attempting to write something other than a String or Buffer without having set objectMode in the options will throw an error. This is not a through or through2 stream. It doesn't transform the data, it just passes it right through. If you want to transform the data, extend the class, and override the write() method. Once you're done transforming the data however you want, call super.write() with the transform output.
