기본 스토리 구조

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

복합 컴포넌트 스토리 (Composition)

import type { Meta, StoryObj } from "@storybook/react";
import { Sidebar } from "./Sidebar";

  render: () => (
    <Sidebar defaultCollapsed={false}>
      <Sidebar.Header title="Dashboard">
        <Sidebar.CollapseButton iconOnly />
      </Sidebar.Header>

      <Sidebar.Content>
        <Sidebar.Section label="메인">

폼 컴포넌트 스토리

import type { Meta, StoryObj } from "@storybook/react";
import { Input } from "./Input";

const meta: Meta<typeof Input> = {
  title: "Atoms/Input",
  component: Input,
  tags: ["autodocs"],
  argTypes: {
    type: {
      control: "select",
      options: ["text", "email", "password", "number"],
    },
    disabled: { control: "boolean" },
    error: { control: "text" },
  },
};

export default meta;
type Story = StoryObj<typeof Input>;

export const Default: Story = {
  args: {
    placeholder: "입력하세요",
  },
};

export const WithLabel: Story = {
  render: () => (
    <div className="space-y-2">
      <label htmlFor="email" className="text-sm font-medium">
        이메일
      </label>
      <Input id="email" type="email" placeholder="email@example.com" />

    </div>
  ),
};

export const Password: Story = {
  args: {
    type: "password",
    placeholder: "비밀번호",
  },

인터랙티브 스토리

import { useState } from "react";

export const Controlled: Story = {
  render: function ControlledStory() {
    const [value, setValue] = useState("");

    return (
      <div className="space-y-4">
        <Input value={value} onChange={(e) => setValue(e.target.value)} placeholder="입력하세요" />
        <p className="text-sm text-gray-500">입력값: {value || "(없음)"}</p>
      </div>
    );
  },
};

export const WithValidation: Story = {
  render: function ValidationStory() {
    const [value, setValue] = useState("");
    const [error, setError] = useState("");

    const validate = (v: string) => {
      if (!v) setError("필수 입력입니다");
      else if (v.length < 3) setError("3자 이상 입력하세요");
      else setError("");
    };

    return (
      <div className="space-y-2">
        <Input
          value={value}
          onChange={(e) => {
            setValue(e.target.value);
            validate(e.target.value);
          }}
          aria-invalid={!!error}
        />
        {error && <p className="text-sm text-red-500">{error}</p>}
      </div>
    );
  },
};

스토리 체크리스트

• 모든 variants가 스토리로 존재
• 모든 sizes가 스토리로 존재
• disabled/loading 상태 스토리
• 에러 상태 스토리 (폼 컴포넌트)
• 인터랙티브 예제 (필요시)
• autodocs 태그 추가
• argTypes 정의 (controls)
