[nextjs]SNS Server-38(myapp48) – freelifemakers.org

👉🏻 myapp48에서는 로컬 SNS페이지에서 글쓰기 폼을 추가합니다.
In myapp48, a post creation form is added to the local social media page.

👉🏻 작성한 글이 public / unlisted / private로 구분해서 저장되도록 데이터베이스 테이블을 수정합니다.
Modify the database table so that written posts are saved with a classification of public, unlisted, or private.

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

📁 데이터베이스 테이블 수정
Modify database table

— 아래의 SQL문을 Sqlite에서 한줄씩 실행합니다.
Execute the SQL statements below in SQLite one line at a time.

-- 1. posts에 visibility + 필요한 컬럼 추가
Add visibility and necessary columns to the `posts` table.

ALTER TABLE posts ADD COLUMN visibility TEXT DEFAULT 'public' CHECK(visibility IN ('public','unlisted','private','direct'));
ALTER TABLE posts ADD COLUMN original_id TEXT;
ALTER TABLE posts ADD COLUMN sensitive INTEGER DEFAULT 0;

-- 2. inbox_posts에 visibility + type + sensitive 추가 (리모트 글 구분)
Added `visibility`, `type`, and `sensitive` to `inbox_posts` (to distinguish remote posts).

ALTER TABLE inbox_posts ADD COLUMN visibility TEXT DEFAULT 'public' CHECK(visibility IN ('public','unlisted','private','direct'));
ALTER TABLE inbox_posts ADD COLUMN type TEXT DEFAULT 'Note';
ALTER TABLE inbox_posts ADD COLUMN sensitive INTEGER DEFAULT 0;

-- 3. outbox에도 visibility 추가 (배달할때 to/cc 구분용)
Added visibility to the outbox as well (to distinguish between 'To' and 'CC' during delivery).

ALTER TABLE outbox ADD COLUMN visibility TEXT DEFAULT 'public';

-- 4. 인덱스 보강 (타임라인 속도)
Index Reinforcement (Timeline Speed)

CREATE INDEX IF NOT EXISTS idx_posts_visibility ON posts(visibility);
CREATE INDEX IF NOT EXISTS idx_inbox_visibility ON inbox_posts(visibility);
CREATE INDEX IF NOT EXISTS idx_outbox_visibility ON outbox(visibility);

📁 파일 추가 / Add file – visibility

✔️ lib/visibility.ts

— 쿠키에 있는 값으로 session테이블의 유저를 검색하고 SNS페이지의 글을 public’ | ‘unlisted’ | ‘private’ 별로 필터링 하는 기능입니다.
This feature searches for a user in the session table using a value from a cookie and filters posts on the SNS page based on visibility settings: ‘public’, ‘unlisted’, or ‘private’.

— 자세한 코드내용은 깃허브 코드를 참조 하세요
Please refer to the GitHub repository for detailed code.

export type Visibility = 'public' | 'unlisted' | 'private' | 'direct';

export function getViewerFromRequest(req: Request): string | null { ... }
export function isFollower(viewer: string, author: string): boolean { ... }
