# 페이지네이션

> UserPaginator와 제네릭 paginator 유틸리티를 사용하여 TypeScript에서 X API 응답을 페이지네이션하세요. 모든 list 엔드포인트에서 수동 fetchNext 루프 또는 비동기 반복을 사용할 수 있습니다.

SDK는 페이지네이션 응답을 반환하는 모든 엔드포인트와 함께 사용할 수 있는 제네릭 paginator 유틸리티를 제공합니다. 메서드는 일반 응답을 반환하며, 이를 paginator로 감쌉니다.

### 기본 페이지네이션

<CodeGroup dropdown>
  ```typescript title="quick-start.ts" lines wrap icon="square-js" theme={null} theme={null}
  import { Client, UserPaginator, PaginatedResponse, Schemas } from '@xdevplatform/xdk';

  const client: Client = new Client({ bearerToken: 'your-bearer-token' });

  // Wrap any list endpoint with proper typing
  const followers: UserPaginator = new UserPaginator(
    async (token?: string): Promise<PaginatedResponse<Schemas.User>> => {
      const res = await client.users.getFollowers('<userId>', {
        maxResults: 100,
        paginationToken: token,
        userFields: ['id','name','username'],
      });
      return { 
        data: res.data ?? [], 
        meta: res.meta, 
        includes: res.includes, 
        errors: res.errors 
      };
    }
  );
  ```

  ```javascript title="quick-start.js" lines wrap icon="square-js" theme={null} theme={null}
  import { Client } from '@xdevplatform/xdk';
  import { UserPaginator } from '@xdevplatform/xdk';

  const client = new Client({ bearerToken: 'your-bearer-token' });

  const followers = new UserPaginator(async (token) => {
    const res = await client.users.getFollowers('<userId>', {
      maxResults: 100,
      paginationToken: token,
      userFields: ['id','name','username'],
    });
    return { data: res.data ?? [], meta: res.meta, includes: res.includes, errors: res.errors };
  });
  ```
</CodeGroup>

### 수동 페이징

<CodeGroup>
  ```typescript manual.ts theme={null} theme={null}
  import { UserPaginator, Schemas } from '@xdevplatform/xdk';

  await followers.fetchNext();          // first page
  while (!followers.done) {
    await followers.fetchNext();        // subsequent pages
  }

  const userCount: number = followers.users.length;  // all fetched users
  const firstUser: Schemas.User | undefined = followers.users[0];
  const nextToken: string | undefined = followers.meta?.nextToken;
  ```

  ```javascript manual.js theme={null} theme={null}
  await followers.fetchNext();
  while (!followers.done) await followers.fetchNext();
  console.log(followers.items.length);
  ```
</CodeGroup>

### 비동기 반복

<CodeGroup>
  ```typescript async.ts theme={null} theme={null}
  import { Schemas } from '@xdevplatform/xdk';

  for await (const user of followers) {
    const typedUser: Schemas.User = user;
    console.log(typedUser.username);  // fully typed access
  }
  ```

  ```javascript async.js theme={null} theme={null}
  for await (const user of followers) {
    console.log(user.username);
  }
  ```
</CodeGroup>

### 새 인스턴스로서의 다음 페이지

<CodeGroup>
  ```typescript next.ts theme={null} theme={null}
  import { UserPaginator } from '@xdevplatform/xdk';

  await followers.fetchNext();
  if (!followers.done) {
    const page2: UserPaginator = await followers.next(); // independent paginator starting at next page
    await page2.fetchNext();
    console.log(page2.users.length);  // items from second page
  }
  ```

  ```javascript next.js theme={null} theme={null}
  await followers.fetchNext();
  if (!followers.done) {
    const page2 = await followers.next();
    await page2.fetchNext();
  }
  ```
</CodeGroup>

### 오류 처리 및 속도 제한

<CodeGroup>
  ```typescript title="errors.ts" lines wrap icon="square-js" theme={null} theme={null}
  import { UserPaginator, Schemas } from '@xdevplatform/xdk';

  try {
    for await (const item of followers) {
      const user: Schemas.User = item;
      // process user...
    }
  } catch (err: unknown) {
    if (followers.rateLimited) {
      console.error('Rate limited, backoff required');
      // backoff / retry later
    } else {
      console.error('Pagination error:', err);
      throw err;
    }
  }
  ```

  ```javascript errors.js theme={null} theme={null}
  try {
    for await (const item of followers) {
      // ...
    }
  } catch (err) {
    if (followers.rateLimited) {
      // backoff / retry later
    } else {
      throw err;
    }
  }
  ```
