Recently I’ve been using Turbo frames and streams more and wanted to really understand how they work. To do that I set out to rebuild a very simple To-Do application (peak originality!), using Turbo but without Rails or turbo-rails gem. I did that using Sinatra1. As you’ll see, it was really simple. So simple I wondered if it’s worth a blog post. But then I realised that is kind of interesting in itself. At first I wanted to go really bare bones and started writing a pure rack application directly in config.ru file but quickly realised I’m basically recreating a very bad alternative to Sinatra so I moved to it instead. ↩
