QR Editor System

Overview

The QR Editor System is a sophisticated component that enables organizations to generate, customize, and print QR codes for customer feedback collection. The system integrates with the campaign management module to create site-specific QR codes that link directly to feedback forms.

Architecture Components

1. QR Editor Page Structure

File: CustomerFeedbackQrEditorPage.tsx

The QR Editor page uses React’s lazy loading pattern for optimal performance:

import React, { Suspense, lazy } from 'react';
const CustomerFeedbackQrEditor = lazy(() => import('../../components/customerFeedback/CustomerFeedbackQrEditor'));
 
const CustomerFeedbackQREditorPage = () => {
  return (
    <Suspense fallback={<div />}>
      <CustomerFeedbackQrEditor />
    </Suspense>
  );
};

Key Features:

  • Lazy loading for performance optimization
  • Suspense wrapper for loading states
  • Clean separation of page and component logic

2. QR Code Generator Component

File: CustomerFeedbackQrEditor.tsx

The core QR editor component handles the visual generation and customization of QR codes:

Core Functionality:

  • Dynamic QR code generation using react-qr-code
  • Company name and site name customization
  • Print-to-PDF functionality
  • URL parameter handling for campaign data

Key Implementation Details:

// URL Parameter Extraction
const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
const siteName = urlParams.get('name') || 'Default Site Name';
const companyName = urlParams.get('companyName') || 'Company Name';
const campaignUrl = urlParams.get('campaignURL') || dummyUrl;
 
// Print Media Listener for Chat Box Hiding
const setPrintMediaListener = () => {
  const onChangePrintMedia = (queryListener: any) => {
    const chatBox: HTMLCollection = document.getElementsByClassName('fc-widget-normal');
    if (!(chatBox[0] as HTMLElement)?.style) return;
    (chatBox[0] as HTMLElement).style.display = queryListener.matches && chatBox.length ? 'none' : 'block';
  };
  
  if (window.matchMedia) {
    const mediaQueryList = window.matchMedia('print');
    if (mediaQueryList.addEventListener) {
      mediaQueryList.addEventListener('change', onChangePrintMedia);
      return () => mediaQueryList.removeEventListener('change', onChangePrintMedia);
    }
  }
};

Visual Design Features:

  • Custom QR code container with corner decorations
  • Responsive text areas for company and site names
  • Nimbly branding integration
  • Print-optimized styling

3. QR Code Management Interface

File: CustomerFeedbackQRCodes.tsx

The QR Codes management component provides a comprehensive interface for generating and managing QR codes across multiple sites:

Core Features:

  • Site selection with search functionality
  • Pagination for large site lists
  • QR code generation and download
  • Clipboard copy functionality
  • Real-time loading states

Site Selection Logic:

const getSiteOptions = (sites: Sites) => {
  let siteOptions: Option[] = [];
  for (const key in sites) {
    if (sites.hasOwnProperty(key)) {
      let siteObj = {
        value: sites[key].siteID,
        label: sites[key].name,
      };
      siteOptions.push(siteObj);
    }
  }
  setSiteOptions(siteOptions);
};

QR Code Generation Flow:

const onClickDownloadQR = async (name: string, siteID: string, questionnaireId: string) => {
  setDownloading(true);
  try {
    const result = await generateQRLink({ siteID, questionnaireId });
    const campaignURL = result;
    const query = queryString.stringify({ name, campaignURL, companyName });
    const QREditor = `/admin/customerFeedback/qr-editor?` + query;
    window.open(QREditor, '_blank');
  } catch (error) {
    toast.error(error.message);
  }
  setDownloading(false);
};

File: generateQRLink.ts

The QR link generation utility handles the API communication for creating unique campaign URLs:

export interface GenerateHashedLink {
  siteID: string;
  questionnaireId: string;
}
 
export async function generateQRLink(generateHashedLink: GenerateHashedLink) {
  const { siteID, questionnaireId } = generateHashedLink;
  const authToken = await getToken();
  const options = {
    method: 'GET',
    headers: {
      Authorization: authToken,
      'Content-Type': 'application/json',
    },
  };
 
  const query = queryString.stringify({ siteID, questionnaireID: questionnaireId });
  const downloadQRUrl = `${apiURL}/customer-feedback/links?` + query;
  const response = await fetch(downloadQRUrl, options);
  
  if (response.status === 200) {
    const result = await response.json();
    if (!result.data) {
      return 'No Data';
    }
    return result.data;
  } else {
    if (response.status === 404) {
      throw new Error('No Response Found');
    } else {
      const { message } = await response.json();

The main questionnaire editor orchestrates the entire form creation and editing workflow:

Core Features:

  • CRUD Operations: Complete create, read, update, delete functionality for questionnaires
  • Question Validation: Real-time validation with error highlighting
  • Department Ownership: Assignment of questionnaires to specific departments
  • Permission Management: Role-based access control for editing capabilities

Key Implementation Details:

// Questionnaire Creation/Update Flow
const handleSavePublish = () => {
  const { auth, profile } = props;
  if (deptOwner === '') return setIsValidDeptOwner(true);
 
  let hasError = false;
  const newCategoryIds: CategoryIdPool = [...categoryIds];
  const newCategories: CategoryPool = { ...categories };
  const newQuestions: QuestionPool = getQuestionWithChecklist();
  const newQuestionsOrder: QuestionSingle[] = [];
 
  // Validation and error checking
  newCategoryIds.forEach((categoryId) => {
    const { questionIds, selectValue } = newCategories[categoryId];
    questionIds.forEach((questionId) => {
      newQuestions[questionId].category = selectValue.value;
      newQuestions[questionId].categoryID = selectValue['__isNew__'] ? '' : selectValue._id || '';
      newQuestionsOrder.push(newQuestions[questionId]);
    });
  });
 
  // Question validation loop
  newQuestionsOrder.forEach((question: QuestionSingle) => {
    const validationParent = validateQuestion(question);
    if (validationParent.error) {
      hasError = true;
      return hasError;
    }
  });
 
  if (hasError) return;
 
  // Create or update questionnaire
  const questionnaire: QuestionnaireCustomerFeedbackRequest = {
    title: title,
    questions: newQuestionsOrder,
    status: 'published',
    dateCreated: now,
    disabled: true,
    dateUpdated: now,
    type: 'default',
    questionnaireIndexID: questionnaireId === 'new' ? '' : questionnaireId,
    modifiedBy: auth.uid,
    mainDepartmentID: deptOwner,
  };
 
  // Dispatch appropriate action
  if (questionnaireId === 'new') {
    dispatch(postQuestionnaires.request(questionnaire));
  } else {
    dispatch(updateQuestionnaires.request(questionnaire));
  }
};

Question Validation System:

const validateQuestion = (question: QuestionSingle) => {
  const tags: { [key: string]: boolean } = {};
  
  // Normalize numeric fields
  question.photoLimit = Number(question.photoLimit) || 0;
  question.photoMinimum = Number(question.photoMinimum) || 0;
  question.videoLimit = Number(question.videoLimit) || 0;
  question.videoMinimum = Number(question.videoMinimum) || 0;
 
  // Handle multiple choice validation
  if (question.type === 'multiple-choice') {
    question.multipleChoices = question.multipleChoices
      ? question.multipleChoices.map((choice: any) => choice.trim())
      : [];
    const emptyChoiceIndex = question.multipleChoices.indexOf('');
  }
 
  // Score weight validation
  if (question.type === 'score') {
    if (!question.hasOwnProperty('scoreWeight')) {
      question.scoreWeight = question.score;
    } else {
      question.scoreWeight = isNaN(Number(question.scoreWeight)) ? 0 : Number(question.scoreWeight);
    }
  }
 
  // Binary question tags handling
  if (question.type === 'binary-with-red-flag' || question.type === 'binary') {
    if (question.tags) {
      Object.entries(question.tags).map(([key, value]) => {
        if (value) tags[key] = value as any;
      });
    }
  }
 
  // Validation checks
  const hasErrors = emptyChoiceIndex > -1 || 
                   !question.content || 
                   !title || 
                   (question.type === QuestionTypes.SCORE && question.scoreWeight === 0);
 
  return { error: hasErrors, question: question, tags: tags };
};

Question Addition Logic:

const handleAddQuestion = (categoryId: string) => {
  const newCategories: CategoryPool = { ...categories };
  const newQuestions: QuestionPool = { ...questions };
  const newEditingQuestions: EditingQuestionPool = { ...editingQuestions };
 
  const clonedQuestionsIds: string[] = newCategories[categoryId].questionIds.slice();
  const newQuestionsLength: number = Object.keys(newQuestions).length;
  const prevQuestionType: QuestionTypes | null = QuestionTypes.BINARY;
 
  // Create new question with default values
  const newQuestion = new Question(
    prevQuestionType, '', '', 0, 0, 0, 0, [], [], [], undefined, 
    [], '', [], [], '', 0, 0, true, '', '', undefined, undefined,
    undefined, undefined, undefined, '', '', '', null, undefined,
    new ConditionalQuestion({}), [], [], 0, 0, [], undefined, 
    undefined, [], undefined, undefined, undefined, undefined, 
    undefined, undefined
  );
 
  // Handle flag labels for binary questions
  if (newQuestion.type === 'binary-with-red-flag') {
    if (categoryLabelFlags[newQuestion.type]?.[categoryId]) {
      newQuestion.flagLabel = cloneDeep(categoryLabelFlags[newQuestion.type][categoryId]);
    } else if (flagLabel[newQuestion.type]) {
      newQuestion.flagLabel = cloneDeep(flagLabel[newQuestion.type]);
    }
  }
 
  // Update state
  newEditingQuestions[`question-${newQuestionsLength}`] = true;
  clonedQuestionsIds.push(`question-${newQuestionsLength}`);
  newQuestions[`question-${newQuestionsLength}`] = {
    ...newQuestion,
    id: `question-${newQuestionsLength}`,
  };
 
  // Dispatch updates
  dispatch(action.setCategories({
    ...categories,
    [categoryId]: { ...categories[categoryId], questionIds: clonedQuestionsIds },
  }));
  dispatch(action.setQuestions(newQuestions));
  dispatch(action.setEditingQuestions(newEditingQuestions));
 
  // Auto-scroll to new question
  setTimeout(() => {
    const target = document.getElementById(`head-question-${newQuestionsLength}`);
    if (target) {
      target.scrollIntoView({ behavior: 'smooth', block: 'center', inline: 'nearest' });
    }
  }, 500);
};

Drag and Drop Implementation:

const handleDragEnd = (result: DropResult) => {
  const { source, destination } = result;
 
  if (!isEditable || !destination) return;
 
  if (source.droppableId === destination.droppableId) {
    // Reorder within same category
    const items = handleReorderList(getList(source.droppableId), source.index, destination.index);
    dispatch(action.setCategories({
      ...categories,
      [destination.droppableId]: { 
        ...categories[destination.droppableId], 
        questionIds: items 
      },
    }));
  } else {
    // Move between categories
    const result = handleMoveBetweenLists(
      getList(source.droppableId),
      getList(destination.droppableId),
      source,
      destination,
    );
 
    dispatch(action.setCategories({
      ...categories,
      [source.droppableId]: {
        ...categories[destination.droppableId],
        questionIds: result[source.droppableId],
      },
      [destination.droppableId]: {
        ...categories[destination.droppableId],
        questionIds: result[destination.droppableId],
      },
    }));
  }
};

3. Redux State Management

Campaign Features Deep Dive

Campaign Status Management

The system supports three campaign states:

  1. Active: Campaign is live and collecting responses
  2. Inactive: Campaign is disabled but has no responses
  3. Inactive with Responses: Campaign is disabled but has historical data

Status Visual Indicators:

  • Slider Toggle: Interactive status switching
  • Color Coding: Green for active, gray for inactive
  • Response Count: Display of total responses received

Permission System

The campaign management system implements granular permissions:

  • View Permission: Basic campaign viewing capabilities
  • Edit Permission: Status management and campaign modification
  • Create Permission: New campaign creation access
  • Feature Flags: Module-level feature enablement

Mobile Optimization

  • Touch-optimized Cards: Large touch targets for mobile devices
  • Responsive Layout: Adaptive design for different screen sizes
  • Mobile-specific Actions: Tap-to-view functionality
  • Floating Action Button: Quick campaign creation access

Bulk Operations

The bulk upload system supports:

  • Excel Template Generation: Dynamic template creation
  • Validation Rules: File format and size validation
  • Error Reporting: Detailed failure analysis
  • Batch Processing: Multiple campaign creation in single operation
