I posted the source code from my presentation at
https://github.com/hallettj/redux/tree/demo/redux-in-electron.
I started with a stock TodoMVC demo webapp written using React and Redux, and I modified it to run in Electron and to persist state to the filesystem. To see the changes that I made, use git diff:
$ git diff master..demo/redux-in-electron
To run the example, check out the source and run these commands from the project root:
$ git checkout demo/redux-in-electron
$ cd examples/todomvc
$ npm install
$ npm electron
