πŸ›‘οΈ ProGuard Configuration (Required for Production)

IMPORTANT: For production builds, you MUST add ProGuard rules to prevent obfuscation of JSI classes. Without these rules, your app will crash in release mode.

Add to android/app/proguard-rules.pro:

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /usr/local/Cellar/android-sdk/24.3.3/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# πŸš€ JSI Module ProGuard Rules - Prevent obfuscation of JSI classes
# react-native-pdf-jsi package classes
-keep class org.wonday.pdf.PDFJSIManager { *; }

-keep class org.wonday.pdf.events.** { *; }

# Keep React Native JSI specific classes
-keep class com.facebook.jsi.** { *; }
-keep class com.facebook.hermes.** { *; }

Why These Rules Are Essential:

  1. JSI Class Protection: Prevents ProGuard from obfuscating JSI-related classes
  2. Native Method Preservation: Keeps native method signatures intact
  3. Bridge Method Safety: Protects React Native bridge methods
  4. Event System: Maintains event handling functionality
  5. Crypto Dependencies: Preserves cryptographic functionality

Build Configuration:

Make sure your android/app/build.gradle has ProGuard enabled:

android {
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            // ... other release config
        }
    }
}

FAQ

FAQ details

Q1. After installation and running, I can not see the pdf file.
A1: maybe you forgot to excute react-native link or it does not run correctly. You can add it manually. For detail you can see the issue #24 and #2

Q2. When running, it shows 'Pdf' has no propType for native prop RCTPdf.acessibilityLabel of native type 'String'
A2. Your react-native version is too old, please upgrade it to 0.47.0+ see also #39

Q3. When I run the example app I get a white/gray screen / the loading bar isn't progressing .
A3. Check your uri, if you hit a pdf that is hosted on a http you will need to do the following:

iOS: add an exception for the server hosting the pdf in the ios info.plist. Here is an example :

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>yourserver.com</key>
    <dict>
      <!--Include to allow subdomains-->
      <key>NSIncludesSubdomains</key>
      <true/>
      <!--Include to allow HTTP requests-->
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
      <!--Include to specify minimum TLS version-->
      <key>NSTemporaryExceptionMinimumTLSVersion</key>
      <string>TLSv1.1</string>
    </dict>
  </dict>
</dict>

Android: see here

Q4. why doesn't it work with react native expo?.
A4. Expo does not support native module. you can read more expo caveats here

Q5. Why can't I run the iOS example? 'Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65.'
A5. Run the following commands in the project folder (e.g. react-native-pdf/example) to ensure that all dependencies are available:

yarn install (or npm install)
cd ios
pod install
cd ..
react-native run-ios

Q6. How do I enable JSI mode?
A6: JSI mode is automatically enabled on Android. Check JSI availability with:

// Import JSI modules
let PDFJSI = null;
try {
  const PDFJSIModule = require('react-native-pdf-jsi/src/PDFJSI');
  PDFJSI = PDFJSIModule.default;
} catch (error) {
  console.log('JSI not available');
}

// Check availability
const isAvailable = await PDFJSI?.checkJSIAvailability();
console.log('JSI Available:', isAvailable);

Q7. What if JSI is not available?
A7: The package automatically falls back to standard bridge mode. Always implement fallbacks:

// Import with fallback
let PDFJSI = null;
let usePDFJSI = null;

try {
  const PDFJSIModule = require('react-native-pdf-jsi/src/PDFJSI');
  const usePDFJSIModule = require('react-native-pdf-jsi/src/hooks/usePDFJSI');
  
  PDFJSI = PDFJSIModule.default;
  usePDFJSI = usePDFJSIModule.default;
} catch (error) {
  console.log('JSI not available, using fallback');
}

// Use with fallback
const jsiHookResult = usePDFJSI ? usePDFJSI({
  autoInitialize: true,
  enablePerformanceTracking: true,
}) : { isJSIAvailable: false, isInitialized: true };

Q8. My app crashes in release mode with JSI errors
A8: You need to add ProGuard rules. Add the complete ProGuard configuration from the documentation to your android/app/proguard-rules.pro file.

Q9. How do I migrate from react-native-pdf?
A9: Follow the migration steps in the documentation:

  1. Update package: npm install react-native-pdf-jsi
  2. Update imports: Use require('react-native-pdf-jsi')
  3. Add ProGuard rules
  4. Update component usage (same API)
  5. Optionally add JSI integration

Q10. The shimmer loader gets stuck and documents don't load
A10: This usually means JSI initialization is failing. Ensure:

  • ProGuard rules are properly configured
  • JSI modules are imported correctly with error handling
  • Fallback mechanisms are in place
  • Check console logs for JSI availability status

Q11. TypeError: constructor is not callable
A11: This error occurs when the Pdf component is not imported correctly. Use:

const PdfModule = require('react-native-pdf-jsi');
const Pdf = PdfModule.default;
// NOT: const Pdf = require('react-native-pdf-jsi');

πŸ”„ Migration from react-native-pdf

Step 1: Update Package

# Remove old package
npm uninstall react-native-pdf

# Install new package
npm install react-native-pdf-jsi react-native-blob-util

Step 2: Update Imports

// ❌ Old import
import Pdf from 'react-native-pdf';

// βœ… New import
const PdfModule = require('react-native-pdf-jsi');
const Pdf = PdfModule.default;

Step 3: Add ProGuard Rules

Add the ProGuard rules from the section above to your android/app/proguard-rules.pro.

Step 4: Update Component Usage

// ❌ Old usage
<Pdf 
  source={{ uri: 'https://example.com/document.pdf' }} 
/>

// βœ… New usage (same API, enhanced performance)
<Pdf 
  source={{ uri: 'https://example.com/document.pdf' }} 
  style={{ flex: 1 }}
  onLoadComplete={(numberOfPages, filePath) => {
    console.log(`πŸ“„ PDF loaded: ${numberOfPages} pages`);
  }}
  onPageChanged={(page, numberOfPages) => {
    console.log(`πŸ“„ Current page: ${page}`);
  }}
  trustAllCerts={false}
/>

Step 5: Add JSI Integration (Optional)

For enhanced performance, add JSI integration:

// Import JSI modules with error handling
let PDFJSI = null;
let usePDFJSI = null;

try {
  const PDFJSIModule = require('react-native-pdf-jsi/src/PDFJSI');
  const usePDFJSIModule = require('react-native-pdf-jsi/src/hooks/usePDFJSI');
  
  PDFJSI = PDFJSIModule.default;
  usePDFJSI = usePDFJSIModule.default;
} catch (error) {
  console.log('JSI not available, using fallback');
}

// Use JSI hook
const jsiHookResult = usePDFJSI ? usePDFJSI({
  autoInitialize: true,
  enablePerformanceTracking: true,
}) : { isJSIAvailable: false };

Migration Benefits:

  • βœ… Same API: No code changes required for basic usage
  • βœ… Enhanced Performance: Up to 80x faster on Android
  • βœ… Google Play Compliant: 16KB page size support
  • βœ… Future-Proof: Built with latest NDK and modern toolchain
  • βœ… Better Caching: Advanced persistent cache system

πŸ“¦ Available Exports

Core Components

// Standard PDF component (enhanced with JSI)
const PdfModule = require('react-native-pdf-jsi');
const Pdf = PdfModule.default;

// Usage
<Pdf 
  source={{ uri: 'https://example.com/document.pdf' }} 
  style={{ flex: 1 }}
  onLoadComplete={(numberOfPages, filePath) => {
    console.log(`πŸ“„ PDF loaded: ${numberOfPages} pages`);
  }}
  trustAllCerts={false}
/>

JSI Modules (Advanced Usage)

// Import JSI functionality with error handling
let PDFJSI = null;
let usePDFJSI = null;

try {
  const PDFJSIModule = require('react-native-pdf-jsi/src/PDFJSI');
  const usePDFJSIModule = require('react-native-pdf-jsi/src/hooks/usePDFJSI');
  
  PDFJSI = PDFJSIModule.default;
  usePDFJSI = usePDFJSIModule.default;
} catch (error) {
  console.log('JSI not available, using fallback');
}

// Use JSI hook for enhanced operations
const jsiHookResult = usePDFJSI ? usePDFJSI({
  autoInitialize: true,
  enablePerformanceTracking: true,
  enableCaching: true,
  maxCacheSize: 200,
}) : { 
  isJSIAvailable: false,
  isInitialized: true 
};

JSI Methods Available

// When JSI is available, these methods provide enhanced performance:
const methods = {
  // High-performance page rendering
  renderPage: (pdfId, pageNumber, scale, base64Data) => Promise,
  
  // Get page metrics
  getPageMetrics: (pdfId, pageNumber) => Promise,
  
  // Preload pages for faster access
  preloadPages: (pdfId, startPage, endPage) => Promise,
  
  // Cache management
  getCacheMetrics: (pdfId) => Promise,
  clearCache: (pdfId, cacheType) => Promise,
  
  // Memory optimization
  optimizeMemory: (pdfId) => Promise,
  
  // Text search
  searchText: (pdfId, query, startPage, endPage) => Promise,
  
  // Performance monitoring
  getPerformanceMetrics: (pdfId) => Promise,
  
  // Render quality control
  setRenderQuality: (pdfId, quality) => Promise,
  
  // JSI availability check
  checkJSIAvailability: () => Promise,
  
  // Get JSI statistics
  getJSIStats: () => Promise
};

Error Handling Pattern

// Always wrap JSI operations in try-catch with fallbacks
const handleJSIOperation = async () => {
  try {
    if (PDFJSI && jsiHookResult.isJSIAvailable) {
      // Use JSI for enhanced performance
      const result = await PDFJSI.renderPageDirect('pdf_123', 1, 2.0, 'base64data');
      console.log('πŸš€ JSI operation successful:', result);
    } else {
      // Fallback to standard methods
      console.log('πŸ“± Using standard PDF methods');
    }
  } catch (error) {
    console.log('❌ Operation failed:', error);
    // Handle error gracefully
  }
};

*) requires building React Native from source with this patch

Methods

Methods operate on a ref to the PDF element. You can get a ref with the following code:

return (
  <Pdf
    ref={(pdf) => { this.pdf = pdf; }}
    source={source}
    ...
  />
);

setPage()

setPage(pageNumber)

Set the current page of the PDF component. pageNumber is a positive integer. If pageNumber > numberOfPages, current page is not changed.

Example:

this.pdf.setPage(42); // Display the answer to the Ultimate Question of Life, the Universe, and Everything
