Hey @tomadelaney ,
Great questions here! Most of the time I would consider a ‘recommended approach’ more about opinion that can greatly vary from developer to developer based on comfort level, the stack being used in a current build, etc. Understandably examples, official libraries, and documentation can play a large part in decisions to use one tool or library over another. While the following resources both utilize and reference a Rails app, these are the most relevant docs we provide around this development topic at the moment:
Overview: Authenticate a server-side rendered embedded app using Rails and Turbolinks
Sample server-side rendered Rails app converted using Turbolinks.
Beyond that, do keep an eye out for replies or related posts from others in the community that may have additional insights or suggestions. Happy developing and hope this offers a starting point - Cheers!
