How to implement front on Rest api?

Question

Java

Friends, we all know how to work with tymeleaf and mustache. But when I wrote the rest of the application, implementing the service, dto and controllers, I got into a stupor. The rest returns to the client the DTO in json format. But how then to wrap jecson in some kind of template engine? How to assign a key-value (if it needs to be done at all)? How to do it right according to generally accepted standards?

Answer 1

Now it is customary to write SPA for this using any JS framework (any of Angular / React / Vue)

Answer 2

As a colleague noted, this is done through the js framework. If you want to learn a js framework, then a simple framework is VueJS. You can start with it. Well, of course, knowledge of JavaScript or TypeScript is a must.
