A brief timeline in the early days before we decided on our Turbolinks + ERB + Bindings + JS Modules approach.
Unedited, raw and early it shows some of the process, a lot of the reasoning and some of our bias.
I don't have accurate docs of the current state of things (most of this was written in the first 25% of our admin).
https://github.com/shopify/twine and https://github.com/shopify/turbograft are the outcomes
@wyaeld docs are non-existent and unfortunately these as write ups are dated.
Feel free to open an issue or start contributing to the respective repos. @qq99 can be pretty helpful too :)
