errorMap: ValidationErrorMap<UnwrapFormValidateOrFn<TOnMount>, UnwrapFormValidateOrFn<TOnChange>, UnwrapFormAsyncValidateOrFn<TOnChangeAsync>, UnwrapFormValidateOrFn<TOnBlur>, UnwrapFormAsyncValidateOrFn<TOnBlurAsync>, UnwrapFormValidateOrFn<TOnSubmit>, UnwrapFormAsyncValidateOrFn<TOnSubmitAsync>, UnwrapFormValidateOrFn<TOnDynamic>, UnwrapFormAsyncValidateOrFn<TOnDynamicAsync>, UnwrapFormAsyncValidateOrFn<TOnServer>>;
```

Defined in: [packages/form-core/src/FormApi.ts:567](https://github.com/TanStack/form/blob/main/packages/form-core/src/FormApi.ts#L567)

The error map for the form itself.

***

### fieldMetaBase

```ts
fieldMetaBase: Partial<Record<DeepKeys<TFormData>, AnyFieldMetaBase>>;
```

Defined in: [packages/form-core/src/FormApi.ts:586](https://github.com/TanStack/form/blob/main/packages/form-core/src/FormApi.ts#L586)

A record of field metadata for each field in the form, not including the derived properties, like `errors` and such

### isSubmitSuccessful

```ts
isSubmitSuccessful: boolean;
```

Defined in: [packages/form-core/src/FormApi.ts:619](https://github.com/TanStack/form/blob/main/packages/form-core/src/FormApi.ts#L619)

A boolean indicating if the last submission was successful.

***

### isSubmitted

```ts
isSubmitted: boolean;
```

Defined in: [packages/form-core/src/FormApi.ts:607](https://github.com/TanStack/form/blob/main/packages/form-core/src/FormApi.ts#L607)

***

### isSubmitting

```ts
isSubmitting: boolean;
```

Defined in: [packages/form-core/src/FormApi.ts:599](https://github.com/TanStack/form/blob/main/packages/form-core/src/FormApi.ts#L599)

A boolean indicating if the form is currently in the process of being submitted after `handleSubmit` is called.

Goes back to `false` when submission completes for one of the following reasons:
- the validation step returned errors.
- the `onSubmit` function has completed.

Note: if you're running async operations in your `onSubmit` function make sure to await them to ensure `isSubmitting` is set to `false` only when the async operation completes.

This is useful for displaying loading indicators or disabling form inputs during submission.
