Story file template

import React from 'react';
import type { Meta, StoryObj } from '@storybook/react';

const meta: Meta<COMPONENT_PROPS> = { // TODO: Replace COMPONENT_PROPS with the component props type
  title: 'Components/COMPONENT_EXPORT_NAME', // TODO: Replace COMPONENT_EXPORT_NAME with component export name
  component: COMPONENT, // TODO: Replace with the actual component import
  argTypes: {} // TODO: Setup arg types,
  args: {}, // TODO: Pass in default args
};

export default meta;
type Story = StoryObj<COMPONENT_PROPS>; // TODO: Replace COMPONENT_PROPS with the component props type

export const Default: Story = {};
