Our paper was published today: https://www.nature.com/articles/s41586-018-0686-x, which means the public launching of our web app for CRISPR design built using dash!
One feature of the website is using a CSS pseudo element on the Dash loading state to enable an animated loading gif. It’s quite easy to implement, for details, refer to my comment over here: https://community.plotly.com/t/mega-dash-loading-states/5687/21
Everything else is fairly vanilla. I think I got relatively lucky that our program runs relatively quickly and takes small input (DNA sequence and a cutsite location) and produces large output that can be visualized in a number of ways. The web app is currently hosted on Heroku’s beefy performance-L dyno ($500/mo) which makes it even snappier.
Happy to hear any thoughts you might have!
