We have an existing (Apis only) Rails backend, that by default follows the MVC pattern, (at peaks of 700 requests a second). I am tasked with making the same (read-heavy) application in any JavaScript framework. I was advised to follow the MVC structure. So I am considering these 3 ( Sails.js, LoopBack, NestJS). I get that sails is closest to rails, but that's not particularly a priority.
