JavaScript adaptation of JojoDiff by Joris Heirbaut. For more information and to see the API, see the JojoDiff project page on SourceForge. The project is written in C++, then cross-compiled through Emscripten so it can be used by any JavaScript client.
JojoDiff is great because it generates linear patch files, which can be applied in a very memory-efficient manner. We're using this in janpatch - a patching library for embedded systems that can run in very little memory. This allows us to bring delta updates to even the smallest devices. Having JojoDiff available as a JavaScript library makes it easier to integrate in our build tools.
Currently the library is only available as CLI application, but it'll be adapted into a proper library at some point in the near future.
