So I have extensively used hyperapp (1 and 2) for hybrid mobile applications that run the cab of big rigs. We actually won best in show this year at Freight Waves for our two apps.<p>These are medium/larger apps, with lots of functionality, need to hook into native device features (done with ionic capacitor, and custom plugins), and need to be fast, robust, and flexible. Hyperapp has allowed all of those things.<p>Hyperapp can and will work, with larger applications, but hyperapp does not have super strict "guide rails" like other more popular frameworks do, so its up to you to design, and implement a clean code base. It ships with minimum overhead, and you can either roll features you need, or see if someone in the community has created them.<p>I have worked with angular (1,2,4,6) and react for quite a few projects, and I actually work faster, and end up with a better end product using hyperapp. Its an amazing little framework. Sure, not having stricter guide rails you can write very poor apps in hyperapp, it will let you do stuff poorly, but if you play to its strengths, and get comfortable with it, it really shines.
