My ukelonn web application[1] has gone through several iterations:
1. A JSF application using PrimeFaces[2] (started in July 2016 and
abandoned in December 2016)
2. A Vaadin application[3] (on master from December 2016 abandoned in August
2018)
3. A react.js application, with a REST API written using jersey[4],
initially (ie from August 2018 to July 2019) styled with Material
Design Lite (MDL)[5], but currently styled with bootstrap 4[6]
In Vaadin I was using an extension called TouchKit[7] to get a mobile
app'ish look on the application. However TouchKit was kind of, sort of,
abandoned when moving to Vaadin 8. I tried getting the open sourced
version of TouchKit[8] working, providing some Pull Requests to the
project.
But I never got the Vaadin8 version working[9], and sometime in the spring
of 2018 gave up on TouchKit and started moving towards making ukelonn a
react.js application, backed a REST API.
And that approach proved to be so much conceptually simpler and so much
easier to maintain, that I will never be going back again, I think.
(I may switch react.js with something else, like Vue.js or Svelte.js,
but for now react/redux with sagas seems like the simplest to program
and debug)
If anyone are interest I can try to outline the architecture of the
react.js solution (can't do the same for the older versions,
unfortunately, because I can't quite remember how they were put
together...:-) ).
