The avconv utility can be made to work in 'the Unix way' by specifying stdin and/or stdout instead of filenames for the input and output respectively. See: http://libav.org/avconv.html#pipe
Example:
cat input.ts | avconv -i pipe:0 -f mp4 -movflags frag_keyframe pipe:1 | cat > output.mp4
Using node's require('child_process').spawn(), we can pipe streams of video data through avconv's stdin and stdout and thus Stream All The Things.
var fs = require('fs');
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.

When hosting a project on GitHub, it's likely you'll want to use GitHub Pages to host a public web site with examples, instructions, etc. If you're not using a continuous integration service like Travis, keeping your gh-pages site up to date requires continuous wrangling.
The steps below outline how to use Travis CI with GitHub Releases and GitHub Pages to create a "1-button" deployment workflow. After testing and running a release build, Travis will upload your release assets to GitHub. It will also push a new version of your public facing site to GitHub Pages.
Let's assume you are hosting a JavaScript project that will offer a single JavaScript file as a release asset. It's likely you'll organize your files like this.
