HLS streaming from node

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.

// loosely based on https://gist.github.com/bnerd/2011232
// requires node.js >= v0.10.0
// assumes that HLS segmenter filename base is 'out'
// and that the HLS playlist and .ts files are in the current directory

The Client-Side Rendering Problem

The Client-Side Rendering Problem

The core problem with UI rendering boils down to these two questions:

  1. How do you know when something has changed?
  2. How do you most optimally update the UI with those changes?

What has changed?

There are several implementations that can tell you what has been changed, some of which are:
