File Manager Module

The File Manager module provides authenticated file browsing and file operations for the admin app. It has a backend API for storage operations and a frontend UI for browsing, previewing, uploading, renaming, deleting, duplicating, and editing supported files.

Documentation

Page	Purpose
Backend	API routes, services, storage adapter contract, permissions, and extension points.
Frontend	UI structure, React Query and MobX, cache updates, pages, and widgets.

Main Capabilities

• Browse folders and files.
• Filter, sort, and paginate directory entries.
• Preview file details and text content for supported extensions.
• Stream raw files for preview or download.
• Create folders.
• Upload files with progress and cancellation support.
• Rename, delete, and duplicate entries.
• Search entries.
• Open an image editor for image files.
• Pick files through reusable frontend picker components.
• Insert files into RichText editor through reusable frontend picker components.
• Use local filesystem storage or S3-compatible storage through Adonis Drive.

High-Level Flow

Admin route
  -> FileManager frontend page
  -> React Query API hook
  -> /file-manager backend route
  -> FileManagerController
  -> FileManagerService
  -> StorageService adapter
  -> Adonis Drive fs or s3 disk

Data Contract

Backend responses use Entry objects:

type Entry = FileEntry | FolderEntry;

type FileEntry = {
  type: "file";
  name: string;
  path: string;
  url: string;
  size?: number;
  updatedAt?: string;
};

type FolderEntry = {
  type: "folder";
  name: string;
  path: string;
  updatedAt?: string;
};

The frontend maps DTOs into frontend entities and adds UI-oriented metadata such as parent and extension.

Ownership Rules

• Backend owns storage, validation, authorization, path safety, and API response shape.
• Frontend owns navigation, selection, view settings, operation progress, and user interactions.
• React Query owns server state in the frontend.
• MobX stores own local UI and operation state in the frontend.
• Storage adapters must implement storage_service_interface.ts; callers should depend on that interface, not a concrete disk implementation.
• The active storage adapter is selected by DRIVE_DISK.

Common Change Guide

Change	Start Here
Add or change an API route	backend/app/base_modules/FileManager/routes.ts and controller/file_manager_controller.ts
Change path validation or naming rules	services/path_service.ts
Change list filtering, sorting, or pagination	services/entry_list_service.ts and frontend query payloads
Add or change a storage backend	services/storage_service/storage_service_interface.ts, create_storage_service.ts, and Backend storage docs
Add a frontend operation	apps/admin/src/core/FileManager/data/queries/ and relevant store/widget
Add file type icons	apps/admin/public/media/files/ and shared/file/fileTypeImportMap.ts
Add preview support	Backend file_preview_service.ts and frontend view/ui/FilePreview/

Planned Work

• Add more non-filesystem storage adapters such as:
  • Google Cloud Storage
  • Supabase Storage
  • Digital Ocean Spaces
  • Cloudflare R2
• Add testing notes once module-level backend and frontend tests are established.
• Add libs for rendering large lists.
