Why is fieldContext exported when you have useFieldContext?

[cgatian]

Trying to understand why fieldContext is exported in the docs when none of the examples ever use it? Everything is using the hook. 🫤 What am I missing?

I get that it's used to build an useAppForm hook, with createFormHook is that the only use?

The raw fieldContext is exported for one reason: you pass it to createFormHook() to wire up the context system.

// form-context.ts
export const { fieldContext, useFieldContext, formContext, useFormContext } =
  createFormHookContexts()

// form.ts
const { useAppForm } = createFormHook({
  fieldContext, // 👈 This is why it's exported
  formContext,
  fieldComponents: { TextField },
  formComponents: { SubscribeButton },
})

That's it. The pattern is:

1. Create contexts with createFormHookContexts()
2. Pass raw contexts to createFormHook()
3. Use useFieldContext in your custom field components

You'd never call useContext(fieldContext) yourself — useFieldContext does that with proper error handling and typing. The raw context export is just plumbing for the hook factory.

Gotcha. Yeah so its only used for createFormHook.
