Turbo Handbook

Turbo bundles several techniques for creating fast, modern, progressively enhanced web applications without using much JavaScript. It offers a simpler alternative to the prevailing client-side frameworks which put all the logic in the front-end and confine the server side of your app to being little more than a JSON API.With Turbo, you let the server deliver HTML directly, which means all the logic for checking permissions, interacting directly with your domain model, and everything else that goes into programming an application can happen more or less exclusively within your favorite programming language. You’re no longer mirroring logic on both sides of a JSON divide. All the logic lives on the server, and the browser deals just with the final HTML.
