Why use Express, on Vuex with Sequelize?

Question

Express.js

I see everywhere that if the backing is on nodejs, then they do it according to the principle:
Database + orm on Sequelize
AND they access data models through internal server requests via Express like 127.0.0.1:3000/users and determine that, for example, send such a request to the users controller
AND in the users controller is already fetching from the database.
The question is, why raise Express and make tcp requests
If you can make a request from the client for vuex dispatch, for example, the users action and make a selection from the database in it ...

Answer 1

In this case, the client will have access to the database.
