A React component library for rendering and interacting with PDF documents

Core Idea:

React PDF Viewer is a component-based library that provides a customizable PDF viewing experience in React applications, leveraging the PDF.js library to handle rendering and processing of PDF documents.

Key Principles:

1. Component-Based Architecture:
   • Built entirely with React hooks and components, allowing for modular integration
2. Extensibility:
   • Core functionality can be enhanced through plugins and customization options
3. Worker-Based Processing:
   • Utilizes web workers via PDF.js to handle resource-intensive tasks without blocking the UI thread

Why It Matters:

• Enhanced User Experience:
  • Provides intuitive document viewing capabilities directly within web applications
• Developer Flexibility:
  • Offers extensive customization options for tailoring the viewer to specific application needs
• Performance Optimization:
  • Separates rendering and processing tasks to maintain responsive interfaces even with large documents

How to Implement:

1. Install Required Packages:
   • Install PDF.js library: npm install pdfjs-dist@3.4.120
   • Install core package: npm install @react-pdf-viewer/core@3.12.0
2. Set Up Worker:
   • Configure the Worker component with the appropriate worker URL
   • Ensure worker version matches PDF.js version
3. Implement Viewer Component:
   • Import viewer and styles
   • Configure with document source and container dimensions

Example:

• Scenario:
  • Creating a basic PDF viewer in a React application
• Application:

import { Worker, Viewer } from '@react-pdf-viewer/core';
import '@react-pdf-viewer/core/lib/styles/index.css';

const PdfViewerComponent = () => (
  <div style={{ height: '750px', border: '1px solid rgba(0, 0, 0, 0.3)' }}>
    <Worker workerUrl="https://unpkg.com/pdfjs-dist@3.4.120/build/pdf.worker.min.js">
      <Viewer fileUrl="/path/to/document.pdf" />
    </Worker>
  </div>
);

• Result:
  • A fully functional PDF viewer displaying the document with default controls and behaviors
