Is there a lot of business logic on the front-end?

Question

Frontend

Is there a lot of business logic on the front-end? Which projects have a lot of logic on the front? Or is backing the whole logic behind a larger degree of wrapping for data from the back?:

Answer 1

It depends a lot on the project. On some ordinary sites, like blogs or online stores, there may be no logic at all or the bare minimum at the front. On the other hand, there are full-fledged web applications, where there is quite a lot of logic at the front. Especially when the stateless backend approach is used, the state is kept by the client, and accordingly, the client is responsible for the business logic.

Answer 2

Is there a lot of business logic on the front-end?

As a general rule, less is more.
In small ones, or those where information security is not required
Typically, the task of the front is to provide display and control of the interface.

Answer 3

It's called - "thin client" and "thick client"
For example, see Wrike - they have complex software that lives in the browser. Pulling for the sake of every little thing from the business logic from the backend is not comme il faut.

Answer 4

Well, in Figma, the editor is completely at the front, only information about the markup is stored on the server, and in the git.
