Best way to use Pinia store to store values from a form?

[inhibitions]

Let's say I have a form:

<form>
  <section>
    ...
    <input type="text" />
     <Component A />
  </section>
  <section>
    ...
    <input type="number" />
     <Component B />
  </section>
  <section>
    ...
     <Component C />
  </section>
  <div>
    <button>Submit</button>
  </div>
</form>

I decided to put each <section> into a separate component, so now it looks more like this:

<form> 
  <SectionA />
  <SectionB />
  <SectionC />
  <div>
    <button>Submit</button>
  </div>
</form>

Let's say there are 3 levels of nesting in <SectionA /> and 4 levels of nesting in <SectionB />.

Now, I will need a way to collect all the values from each <section> and combine them so I can send them to the API on submit. I can do either of the following:

• Create a Pinia store solely dedicated to holding the form values
• All components inside each <section> component will emit the data back up to the <section> component
• Each <section> component will emit the data to the <form> parent component
• The <form> component will be the only one directly interacting with the Pinia store

OR

• Create a Pinia store solely dedicated to holding the form values
• All components inside each <section> component will directly call the appropriate mutator functions inside the Pinia store whenever a value changes. For example, for the "Birthday" field, it will call the setAge() mutator inside the Pinia store when the user enters a value in that field
• The <section> component will do the same -- directly call the mutator functions inside the Pinia store

I'm leaning towards the second approach as it feels less cumbersome and the data flow would be easier to follow. If I need to emit new data, I don't have to pass through several ancestors.

I suppose an advantage of the first approach is that there is only one place where we're calling the mutator functions? Somehow making it easier to debug? But I'm feeling that this just adds an unnecessary layer of abstraction/difficulty 🤔
