[nextjs]SNS Server-20(myapp30)

👉🏻 myapp30에서는 내가 작성한 글 삭제시 내 글을 받은 서버의 글도 삭제하는 기능을 추가했습니다.
In myapp30, I added a feature that deletes the post on the server that received it whenever I delete my own post.

👉🏻 전체 코드는 깃허브에서 확인 할 수 있습니다.
You can find the full code on GitHub.

📁 코드수정 / Code Modification

 ✔️app/api/posts/route.ts

-- posts만 삭제하고 연방에 Delete 안 보내는 문제 수정
Fixed an issue where only 'posts' were deleted without sending a 'Delete' request to the federation.

1) inbox_posts는 안 지움 + likes, announces 카운트도 안 지움
`inbox_posts` are not deleted, and `likes` and `announces` counts are not cleared either.

2) import { sendDelete } 맨 위에 추가 - 서명 포함된 함수 사용
Add `import { sendDelete }` at the top – use the function that includes the signature.

3) DELETE에서 fetch 직접 호출 -> sendDelete(f.inbox, id, username)로 교체
Replaced direct `fetch` call in `DELETE` with `sendDelete(f.inbox, id, username)`.

4) POST도 for...of await -> Promise.allSettled 병렬로 변경 (속도 향상)
Changed POST requests from `for...of await` to `Promise.allSettled` for parallel execution (improved speed).

✔️app/lib/ap.ts

— 전체 코드 리팩토링 , sendDelete함수 추가
Refactored the entire codebase and added the sendDelete function.

export async function sendDelete(toInbox: string, postId: string, username: string) {
  const actorId = `https://${DOMAIN}/users/${username}`;

  // postId가 이미 전체 URL이면 그대로, UUID면 만들어주기 
  // If postId is already a full URL, use it; if it's a UUID, construct it! 
  const objectId = postId.startsWith('http') 
    ? postId 
    : `${actorId}/statuses/${postId}`; 

  const doc = {
    '@context': 'https://www.w3.org/ns/activitystreams',
    id: `${actorId}#delete/${crypto.randomUUID()}`,
    type: 'Delete',
    actor: actorId,
    object: objectId,
    published: new Date().toISOString(),
    to: ['https://www.w3.org/ns/activitystreams#Public']
  };
  console.log(`🗑 [${username}] Delete -> ${toInbox} (${postId})`);
  const { res, text } = await signAndSend(toInbox, doc, username);
  console.log(`📬 Delete: ${res.status}`, text);
  return { ok: res.ok, status: res.status, text, deleteDoc: doc };
}
