The ThritySeven is the application same with ThirtySix. But the development tools are different, ThirtySix is based on Java with the Spring framework(spring-mvc, spring-data-jpa, spring-security etc), and its front-end are just using jQuery, Bootstrap without any framework. In this version, we'll use another programming language to develop back-end, and using some framework for developing front-end, so below.
We will use the Node.js(v8.x.x) for RESTful API, and use Sequelize to access database.
We will develop two version of front-end, one is using the Angular(ThirtySeven-Angular-Smile), and second is using React(ThirtySeven-React-Smile).
