58-98: Remove residual@types/mime-typesand confirm no legacy imports
- Delete the
"@types/mime-types": "^3.0.1"entry from your package.json.- Re-run a glob-based search (e.g.
rg -n '\bmime-types\b' -C2 -g '*.js' -g '*.ts' -g '*.jsx' -g '*.tsx') to ensure no remainingmime-typesimports/usages.

package.json (1)
122-122: Remove leftover @types/mime-types.
This type package is for the old dependency and can be dropped to avoid confusion.Apply this diff:
- "@types/mime-types": "^3.0.1",src/main/presenter/filePresenter/mime.ts (3)
110-141: Update log strings and stale comment; compute basename once.
Logs still reference “mime.lookup” and comment mentions “file-type”. Minor cleanup and a tiny perf/readability tweak.Apply this diff:
export const detectMimeType = async (filePath: string): Promise<string> => { try { - const mimeType = lookup(filePath) - console.log(`[getMimeType] mime.lookup result for ${path.basename(filePath)}:`, mimeType) + const baseName = path.basename(filePath) + const mimeType = lookup(filePath) + console.log(`[getMimeType] lookup result for ${baseName}:`, mimeType) if (mimeType) { - console.log('Detected by mime.lookup:', mimeType) + console.log('Detected by lookup:', mimeType) return mimeType } // 3. If neither works, try the text heuristic - console.log(`[getMimeType] Trying text heuristic for ${path.basename(filePath)}`) + console.log(`[getMimeType] Trying text heuristic for ${baseName}`) const isText = await isLikelyTextFile(filePath) - console.log(`[getMimeType] isLikelyTextFile result for ${path.basename(filePath)}: ${isText}`) + console.log(`[getMimeType] isLikelyTextFile result for ${baseName}: ${isText}`) return isText ? 'text/plain' : 'application/octet-stream' } catch (error) { - console.error(`[getMimeType] Error before text check for ${path.basename(filePath)}:`, error) - // If file-type or mime.lookup caused an error, still try basic text check + console.error(`[getMimeType] Error before text check for ${path.basename(filePath)}:`, error) + // If lookup caused an error, still try basic text check // or fall back to octet-stream directly depending on desired robustness. // For now, let's try the text check even on error. try { - console.log(`[getMimeType] Trying text heuristic for ${path.basename(filePath)} after error`) + console.log(`[getMimeType] Trying text heuristic for ${path.basename(filePath)} after error`) const isText = await isLikelyTextFile(filePath) console.log( - `[getMimeType] isLikelyTextFile result for ${path.basename(filePath)} after error: ${isText}` + `[getMimeType] isLikelyTextFile result for ${path.basename(filePath)} after error: ${isText}` ) return isText ? 'text/plain' : 'application/octet-stream' } catch (textCheckError) { - console.error(`Error during text check for ${filePath}:`, textCheckError) + console.error(`Error during text check for ${path.basename(filePath)}:`, textCheckError) return 'application/octet-stream' // Final fallback on error } } }
12-13: Prefer explicit Node built-in specifiers.
Not required, but using node:fs/promises and node:path can be clearer in ESM contexts.-import fs from 'fs/promises' -import path from 'path' +import fs from 'node:fs/promises' +import path from 'node:path'
110-141: Consider structured logging (electron-log) per guidelines.
Console logs lack levels/timestamps/structure required by your logging guidance.If you already have a logger, swap console.* with logger.* and include context (file, function, basename).
src/main/presenter/filePresenter/FileValidationService.ts (2)
145-150: Extension resolution OK; optionally collect all known extensions.
Current approach adds only the default extension per MIME. If you want broader coverage (e.g., markdown: md and markdown), consider augmenting via a mapping or library support for multiple extensions.
156-183: Align error logging with project logging standards.
Use your structured logger instead of console.error to include level, timestamp, and context.

79-79: Dependency switch to es-mime-types looks good.
No issues spotted with adding the new dependency.src/main/presenter/filePresenter/mime.ts (1)
14-14: Switch to es-mime-types import is correct.
The named import aligns with the intended usage.src/main/presenter/filePresenter/FileValidationService.ts (1)
4-4: Importing extension from es-mime-types is appropriate.
Reads clean and consistent with the migration.
