file-manager-hooks.ts

Overview

This file contains a set of React hooks designed to interact with a file management system in a web application. These hooks encapsulate the logic for fetching, manipulating, and managing files and folders via asynchronous API calls, primarily using the React Query library for server state management and caching.

The hooks abstract complex operations such as:

This modular approach enables reusable, declarative interaction with the file management backend services while integrating smoothly with UI components.

Detailed Explanation of Exports

1. useGetFolderId

export const useGetFolderId = () => string;

const folderId = useGetFolderId();
console.log(`Current folder ID is: ${folderId}`);

2. IListResult Interface

export interface IListResult {
  searchString: string;
  handleInputChange: React.ChangeEventHandler<HTMLInputElement>;
  pagination: PaginationProps;
  setPagination: (pagination: { page: number; pageSize: number }) => void;
  loading: boolean;
}

3. useFetchPureFileList

export const useFetchPureFileList: () => {
  loading: boolean;
  fetchList: (parentId: string) => Promise<any>;
};

const { loading, fetchList } = useFetchPureFileList();
const files = await fetchList('folder123');

4. useFetchFileList

export const useFetchFileList: () => ResponseType<any> & IListResult;

const {
  data,
  searchString,
  handleInputChange,
  pagination,
  setPagination,
  loading,
} = useFetchFileList();

// Use in UI to display files and handle search & pagination

5. useDeleteFile

export const useDeleteFile: () => {
  data: any;
  loading: boolean;
  deleteFile: (params: { fileIds: string[]; parentId: string }) => Promise<number>;
};

const { deleteFile, loading } = useDeleteFile();
await deleteFile({ fileIds: ['file1'], parentId: 'folder1' });

6. useDownloadFile

export const useDownloadFile: () => {
  data: any;
  loading: boolean;
  downloadFile: (params: { id: string; filename?: string }) => Promise<void>;
};

const { downloadFile } = useDownloadFile();
downloadFile({ id: 'file123', filename: 'document.pdf' });

7. useRenameFile

export const useRenameFile: () => {
  data: any;
  loading: boolean;
  renameFile: (params: { fileId: string; name: string }) => Promise<number>;
};

const { renameFile } = useRenameFile();
renameFile({ fileId: 'file1', name: 'newName.txt' });

8. useFetchParentFolderList

export const useFetchParentFolderList: () => IFolder[];

const parents = useFetchParentFolderList();
console.log(parents);

9. useCreateFolder

export const useCreateFolder: () => {
  data: any;
  loading: boolean;
  createFolder: (params: { parentId: string; name: string }) => Promise<number>;
};

const { createFolder } = useCreateFolder();
createFolder({ parentId: 'folder1', name: 'New Folder' });

10. useUploadFile

export const useUploadFile: () => {
  data: any;
  loading: boolean;
  uploadFile: (params: { fileList: UploadFile[]; parentId: string }) => Promise<number | void>;
};

const { uploadFile } = useUploadFile();
uploadFile({ fileList: filesArray, parentId: 'folder1' });

11. useConnectToKnowledge

export const useConnectToKnowledge: () => {
  data: any;
  loading: boolean;
  connectFileToKnowledge: (params: IConnectRequestBody) => Promise<number>;
};

const { connectFileToKnowledge } = useConnectToKnowledge();
connectFileToKnowledge({ fileId: 'file1', knowledgeId: 'knowledge123' });

12. useMoveFile

export interface IMoveFileBody {
  src_file_ids: string[];
  dest_file_id: string;
}

export const useMoveFile: () => {
  data: any;
  loading: boolean;
  moveFile: (params: IMoveFileBody) => Promise<number>;
};

const { moveFile } = useMoveFile();
moveFile({ src_file_ids: ['file1'], dest_file_id: 'folder2' });
