I have been using a slight variant of this for full page rendering of react apps and its working great. Almost entirely replacing eex templates and relying solely on server side rendered + hydrated react on the client. This pattern is a bit against the grain, and rather than attempting to avoid javascript within Phoenix front-ends, it embraces it!
I have not really built much using eex templates, and generally find myself reaching for react when building decently complex UIs in Phoenix apps. I do have a javascript background, more specifically Meteor, so I suppose it is just what I am more familiar with.
I think for people coming from node, or react backgrounds, this pattern would help ease them into using phoenix on the back-end, and maybe help grow the community!
