There are tons of JS stacks that exist right now - Sails, Adonis, etc. - but I feel they all miss having a hugely profitable business using them in production.

There are tons of JS stacks that exist right now - Sails, Adonis, etc. - but I feel they all miss having a hugely profitable business using them in production. Rails had 37signals use it for all their products - along with having DHH too. Right now you have FRAMEWORKS being used in production at big companies, so if you use React, Angular, etc. you know that you're in good company. I think it would be super interesting having a large company roll out a full stack JS framework that they themselves use.
