Is it necessary to create a ui component(s) for a single call in one page?

Question

I am about to create a Vue.js project and i use the smart/dumb pattern for my ui components. In my dumb components I have already the input, buttons and etc..., but in my smart components I am curios if it is really necessary to create a component if i will use that only in one page. For example. login-form component, then i will use that only in login page. So, ⤵️

My first question, is it really necessary to create a component for that ?

Second question, and when will i gonna create a smart components?

Answer 1

1. Moving code to another components makes code of initial component more readable. Even if you are going to use that new components only once.

2. Usually smart components - are pages that fetch or simply share some data to its children.
