We have tools (Basically CRUD operations in multiple lists across sites/site collections. Handles large amount of data and has lots of business functionalities/logic) that were built using jQuery and Datatables.js. We are planning to rebuild in 2013. Visual Studio/ server side coding is not allowed.
Difficult to get Node.JS/NPM/CLI on DEV environment. we have tried a PoC in Angular 4 using SystemJs-Manual mapping concept. But not sure how bundling and future upgrade will be if CLI/NPM is not used.
