📁 테마 디렉토리나 파일이름 변경시 서버로그에 에러 로그 출력 오류 수정
Fixed an issue where error logs were generated in the server logs when renaming theme directories or filenames.

✔️ 오류 / Error

⨯ ./app/usersui/[username]/_components/themes/index.ts:4:1
Error: Module not found: Can't resolve './themeex/PinaforeTheme'

✔️ lib/watchThemes.ts

      for (const folderName of folders) {
        const folderPath = path.join(themesDir, folderName);
        try { 
... ...
          // ✅ myapp58 
          // -  pinafore는 _Fallback 
          if (folderName === 'pinafore') {
            registryLines += ` pinafore: { component: _Fallback, label: 'pinafore' },\n`;
          } else {
            // ✅ 정적 import 안함, require를 try/catch + eval로 감싸서 번들러가 파일 없어도 에러 안 내게
            registryLines += ` ${folderName}: { component: _load('./${folderName}/${fileBase}', '${exported}'), label: '${folderName}' },\n`;
          }
        } catch { continue; } // 폴더 읽기 실패하면 스킵 / Skip if folder reading fails
      }

      // ✅ myapp58 - write code to index.ts themeName.ts files
      // 디렉토리나 파일 인식 못하면 Pinafore테마로 대체 / If directories or files are not recognized, replace with the Pinafore theme.
      const indexContent = `import { PinaforeTheme as _Fallback } from './pinafore/PinaforeTheme';

function _load(path: string, exportName: string) {
  try {
    const mod = eval('require')(path);
    return mod[exportName] || mod.default || _Fallback;
  } catch {
    return _Fallback;
  }
}

export const themeRegistry = {
${registryLines}} as const;
export type ThemeName = keyof typeof themeRegistry;
export function getThemeComponent(name: ThemeName) {
  return themeRegistry[name]?.component?? _Fallback;
}
`;
      const namesContent = `export const themeNames = ${JSON.stringify(validFolders)} as const;
export type ThemeName = typeof themeNames[number];
`;

✔️ app/usersui/[username]/_components/themes/index.ts – 자동생성 파일 / Automatically generated file

— index.ts파일은 아래와 같은 형식으로생성 됩니다.
The index.ts file is generated in the following format.

import { PinaforeTheme as _Fallback } from './pinafore/PinaforeTheme';

function _load(path: string, exportName: string) {
  try {
    
    const mod = eval('require')(path);
    return mod[exportName] || mod.default || _Fallback;
  } catch {
    return _Fallback;
  }
}

export const themeRegistry = {
 mastodon: { component: _load('./mastodon/MastodonTheme', 'MastodonTheme'), label: 'mastodon' },
 minimal: { component: _load('./minimal/MinimalTheme', 'MinimalTheme'), label: 'minimal' },
 pinafore: { component: _Fallback, label: 'pinafore' },
 themeex: { component: _load('./themeex/Themetheme', 'Theme'), label: 'themeex' },
} as const;
export type ThemeName = keyof typeof themeRegistry;
export function getThemeComponent(name: ThemeName) {
  return themeRegistry[name]?.component?? _Fallback;
}
