use-rename-document.ts

Overview

The use-rename-document.ts file defines a custom React hook named useRenameDocument designed to manage the renaming process of a document within an application. It encapsulates the state and behaviors needed to display a rename modal dialog, handle user input for renaming, and persist the new document name via an asynchronous API request.

This hook provides a clean and reusable interface to integrate document renaming functionality into React components, abstracting away modal state management and server communication.

Detailed Explanation

useRenameDocument Hook

Purpose

useRenameDocument is a custom React hook that:

• Manages the visibility state of a rename modal dialog.

• Stores the currently selected document record (to rename).

• Handles the asynchronous saving of a new document name.

• Exposes methods and state for components to implement rename UI and logic.

Imports Used

• useSetModalState: Custom hook managing modal visibility state (visible, showModal, hideModal).

• useSaveDocumentName: Custom hook that provides a method to asynchronously save the document name, also exposes loading state.

• IDocumentInfo: TypeScript interface describing the structure of a document record.

• React hooks: useState for local state, useCallback for memoizing callbacks.

Hook Signature

export const useRenameDocument: () => {
  renameLoading: boolean;
  onRenameOk: (name: string) => Promise<void>;
  renameVisible: boolean;
  hideRenameModal: () => void;
  showRenameModal: (row: IDocumentInfo) => void;
  initialName?: string;
};

Internal State and Variables

• record: IDocumentInfo | undefined - Stores the current document being renamed.

• saveName and loading - From useSaveDocumentName, used to save the document name and track request status.

• Modal state (renameVisible, showRenameModal, hideRenameModal) - from useSetModalState.

Methods

• onRenameOk(name: string): Promise<void>

  • Triggered when the user confirms the rename action.

  • Checks if a valid document id exists.

  • Calls saveName with { documentId, name }.

  • If the save operation returns 0 (assumed success), it hides the rename modal.

  • Parameters:

    • name - New name for the document.

  • Returns: Promise resolving when the rename operation completes.

  • Usage example:

    await onRenameOk('New Document Title');
    

• handleShow(row: IDocumentInfo): void

  • Used to open the rename modal and set the current document record.

  • Sets record to the document passed in, then displays the modal.

  • Parameters:

    • row - The document information to rename.

  • Usage example:

    showRenameModal(documentRecord);
    

Returned Object

The hook returns an object containing:

• renameLoading: boolean — Indicates if the rename save request is in progress.

• onRenameOk: (name: string) => Promise<void> — Function to trigger rename save.

• renameVisible: boolean — Modal visibility flag.

• hideRenameModal: () => void — Function to hide the rename modal.

• showRenameModal: (row: IDocumentInfo) => void — Function to show the rename modal with a document context.

• initialName?: string — The current name of the document, useful for initializing form inputs.

Type Alias

export type UseRenameDocumentShowType = Pick<
  ReturnType<typeof useRenameDocument>,
  'showRenameModal'
>;

• Defines a type that picks only the showRenameModal method from the hook's return type.

• Useful for typing props or parameters when only the modal show function is needed.

Important Implementation Details

• Modal State Management:
  The hook delegates modal visibility management to the useSetModalState hook, ensuring separation of concerns and reusability.

• Asynchronous Save Logic:
  The rename confirmation method onRenameOk uses async/await to handle asynchronous server calls. It only closes the modal if the save operation returns 0, indicating success (likely a backend status code).

• State Memoization:
  Both onRenameOk and handleShow are memoized with useCallback to avoid unnecessary re-renders or function re-creations when used in React components.

• Safe Access:
  The hook safely checks for the presence of record?.id before attempting to save, preventing runtime errors if no document is selected.

Interaction with Other Parts of the System

• Hooks Dependency:

  • useSetModalState: Provides modal behavior abstraction, possibly used across multiple components or modals in the app.

  • useSaveDocumentName: Handles API communication for document renaming, abstracting request details and loading state.

• Interface Dependency:

  • IDocumentInfo: Defines the shape of document data, ensuring type safety when managing documents.

• Usage Context:

  • Typically used in components responsible for document management or editing, where users can trigger rename actions.

  • Integrates with UI elements such as modals, input forms, and buttons to show rename dialogs and submit new names.

Usage Example

import React from 'react';
import { useRenameDocument } from './use-rename-document';

const DocumentList = ({ documents }) => {
  const { renameVisible, renameLoading, onRenameOk, hideRenameModal, showRenameModal, initialName } = useRenameDocument();

  return (
    <>
      {documents.map(doc => (
        <div key={doc.id}>
          <span>{doc.name}</span>
          <button onClick={() => showRenameModal(doc)}>Rename</button>
        </div>
      ))}

      {renameVisible && (
        <RenameModal
          initialName={initialName}
          loading={renameLoading}
          onOk={onRenameOk}
          onCancel={hideRenameModal}
        />
      )}
    </>
  );
};

Summary

use-rename-document.ts is a concise utility hook providing a standardized and reactive way to rename documents in a React application. It cleanly integrates modal visibility management, asynchronous API calls, and per-document state handling, enabling components to easily implement rename functionality with minimal boilerplate.
