hooks.ts

Overview

The hooks.ts file defines a custom React hook, useClickDrawer, that manages the state and behavior related to displaying a modal drawer with document reference information. Specifically, it handles the visibility of a modal, the currently selected document chunk, and the associated document ID. This hook leverages another custom hook, useSetModalState, to control modal visibility and integrates React's useState and useCallback for state management and event handling.

This file is designed to be used in React components that require a modal drawer interface for displaying or interacting with chunks of referenced documents, facilitating user interactions such as clicking a button to open the modal with specific document content.

Detailed Description

useClickDrawer Hook

Purpose

Manages modal drawer visibility and state related to the document chunk selected by the user.

Function Signature

const useClickDrawer = () => {
  // returns an object with modal control and state properties
};

Returned Object Properties

Parameters

This hook takes no parameters.

Internals and Implementation Details

• State Management:

  • visible, showModal, and hideModal are destructured from useSetModalState(), a custom hook presumably handling modal visibility state.

  • selectedChunk is a state variable holding the currently selected document chunk of type IReferenceChunk.

  • documentId is a state variable holding the string identifier of the document associated with the selected chunk.

• Callback Function:

  • clickDocumentButton is memoized with useCallback to prevent unnecessary re-renders.

  • When invoked (e.g., on a button click), it:

    • Triggers the modal to show by calling showModal().

    • Sets the currently selected chunk using setSelectedChunk(chunk).

    • Sets the current document ID with setDocumentId(documentId).

This design cleanly separates concerns by using a custom modal state hook and providing a concise API for components to open the modal with specific document data.

Usage Example

import React from 'react';
import { useClickDrawer } from '@/hooks/hooks';
import { IReferenceChunk } from '@/interfaces/database/chat';

const DocumentListItem = ({ documentId, chunk }: { documentId: string; chunk: IReferenceChunk }) => {
  const {
    clickDocumentButton,
    visible,
    hideModal,
    selectedChunk,
  } = useClickDrawer();

  return (
    <>
      <button onClick={() => clickDocumentButton(documentId, chunk)}>
        Show Document Chunk
      </button>

      {visible && (
        <Modal onClose={hideModal}>
          <h2>Document ID: {documentId}</h2>
          <p>{selectedChunk.content}</p>
        </Modal>
      )}
    </>
  );
};

In this example, clicking the button calls clickDocumentButton to open the modal with the selected chunk and document ID.

Interaction with Other System Parts

• useSetModalState (imported from @/hooks/common-hooks):

  This hook is responsible for the core modal state management (visibility toggling). useClickDrawer extends this functionality by integrating document chunk and ID state management on top.

• IReferenceChunk Interface (imported from @/interfaces/database/chat):

  Represents the structure of a document chunk. The hook uses this interface for typing the selected chunk state.

• React Components:

  This hook is intended to be used by React components that require modal drawers displaying document reference chunks, facilitating user interactions like selecting and viewing document content.

Summary

• Provides a simple API for opening a modal drawer with a selected document chunk.

• Integrates modal visibility state with document-specific state.

• Uses React hooks (useState and useCallback) to manage internal state and performance.

• Depends on external modal state hook (useSetModalState) and document chunk interface (IReferenceChunk).
