Croogo adds json-api support just before version 4.0.5. It would be interesting to see how it fares when used as datasource for a SPA application. What better way to test this by dogfooding our own stuff? So I tried writing a very simple react application. The code is now open-sourced.
The landing page is basically hardcoded. It only has 2 basic layouts and do only what I need at the time. This application is now used as in croogo.org website itself. The theme style is based on LazyKit UI Kit. Let me know what you think in the comments. Oh wait. It's not coded yet.
