data-* props

The component further forwards all data- attributes to the underlying input component.

errors

This object is a key-value map. The renderError prop will be called for each entry with the key and the value. The return value will be rendered inside an ErrorMessage component underneath the input.

The LocalizedTextField supports some errors out of the box. Return undefined from renderError for these and the default errors will be shown instead. This prevents consumers from having to reimplement the same error messages for known errors while still keeping the flexibility of showing custom error messages for them.

When the key is known, and when the value is truthy, and when renderError returned undefined for that error entry, then the LocalizedTextField will render an appropriate error automatically.

Known error keys are:

• missing: tells the user that this field is required

Static methods

LocalizedTextField.toFieldErrors

Use this function to convert the Formik errors object type to our custom field errors type. This is primarily useful when using TypeScript.

type FormValues = {
  myField: string;
};

<LocalizedTextField
  // ...
  name="my-field"
  errors={LocalizedTextField.toFieldErrors<FormValues>(formik.errors).myField}
/>;
