A quick overview of the node.js streams interface with basic examples.
This is based on @brycebaril's presentation, Node.js Streams2 Demystified
Streams are a first-class construct in Node.js for handling data.
Think of them as as lazy evaluation applied to data.
Provided that you already have a file or stream segmenter generating your .m3u8 playlist and .ts segment files (such as the ffmpeg 'hls' muxer), this little node server will serve up those files to an HLS compatible client (e.g. Safari). If you're using node for your streaming app already, this obviates the need to serve the HLS stream from a separate web server.
