## 📖 Usage
### Basic Usage
```js
import React from 'react';
import { StyleSheet, Dimensions, View } from 'react-native';
import Pdf from 'react-native-pdf-enhanced';
export default class PDFExample extends React.Component {
render() {
const source = { uri: 'http://samples.leanpub.com/thereactnativebook-sample.pdf', cache: true };
//const source = require('./test.pdf'); // ios only
//const source = {uri:'bundle-assets://test.pdf' };

//const source = {uri:"data:application/pdf;base64,JVBERi0xLjcKJc..."};
//const source = {uri:"content://com.example.blobs/xxxxxxxx-...?offset=0&size=xxx"};
//const source = {uri:"blob:xxxxxxxx-...?offset=0&size=xxx"};
return (
<View style={styles.container}>
<Pdf
source={source}
onLoadComplete={(numberOfPages,filePath) => {
console.log(`Number of pages: ${numberOfPages}`);
}}
onPageChanged={(page,numberOfPages) => {
console.log(`Current page: ${page}`);
}}
onError={(error) => {
console.log(error);
}}
onPressLink={(uri) => {
console.log(`Link pressed: ${uri}`);
}}
style={styles.pdf}/>
</View>
)
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'flex-start',
alignItems: 'center',
marginTop: 25,
},
pdf: {
flex:1,
width:Dimensions.get('window').width,
height:Dimensions.get('window').height,
}
});
```
### 🚀 JSI Enhanced Usage
#### Using Enhanced PDF View Component
```js
import React from 'react';
import { View } from 'react-native';
import { EnhancedPdfView } from 'react-native-pdf-enhanced';
export default function EnhancedPDFExample() {
return (
<View style={{ flex: 1 }}>
<EnhancedPdfView
source={{ uri: 'http://example.com/document.pdf' }}
onLoadComplete={(pages) => {
console.log(`🚀 Loaded ${pages} pages with JSI acceleration`);
}}
style={{ flex: 1 }}
/>
</View>
);
}
```
#### Using React Hooks for JSI Operations
```js
import React, { useEffect } from 'react';
import { View, Button } from 'react-native';
import { usePDFJSI } from 'react-native-pdf-enhanced';
export default function JSIHookExample() {
const {
isJSIAvailable,
renderPage,
preloadPages,
getPerformanceMetrics,
getPerformanceHistory
} = usePDFJSI({
autoInitialize: true,
enablePerformanceTracking: true
});
const handleJSIOperations = async () => {
try {
// High-performance page rendering
const result = await renderPage('pdf_123', 1, 2.0, 'base64data');
console.log('🚀 JSI Render result:', result);
// Preload pages for faster access
const preloadSuccess = await preloadPages('pdf_123', 1, 5);
console.log('🚀 Preload success:', preloadSuccess);
// Get performance metrics
const metrics = await getPerformanceMetrics('pdf_123');
console.log('🚀 Performance metrics:', metrics);
} catch (error) {
console.log('JSI operations failed:', error);
}
};
return (
<View style={{ flex: 1, padding: 20 }}>
<Button
title={`JSI Available: ${isJSIAvailable ? '✅' : '❌'}`}
onPress={handleJSIOperations}
/>
</View>
);
}
```
#### Advanced JSI Operations
```js
import React, { useRef, useEffect } from 'react';
import { View } from 'react-native';
import Pdf from 'react-native-pdf-enhanced';
export default function AdvancedJSIExample() {
const pdfRef = useRef(null);
useEffect(() => {
// Check JSI availability and performance
if (pdfRef.current) {
pdfRef.current.getJSIStats().then(stats => {
console.log('🚀 JSI Stats:', stats);
console.log('Performance Level:', stats.performanceLevel);
console.log('Direct Memory Access:', stats.directMemoryAccess);
});
}
}, []);
const handleAdvancedOperations = async () => {
if (pdfRef.current) {
try {
// Batch operations for better performance
const operations = [
{ type: 'renderPage', page: 1, scale: 1.5 },
{ type: 'preloadPages', start: 2, end: 5 },
{ type: 'getMetrics', page: 1 }
];
// Execute operations
for (const op of operations) {
switch (op.type) {
case 'renderPage':
await pdfRef.current.renderPageWithJSI(op.page, op.scale);
break;
case 'preloadPages':
await pdfRef.current.preloadPagesWithJSI(op.start, op.end);
break;
case 'getMetrics':
const metrics = await pdfRef.current.getJSIPerformanceMetrics();
console.log('📊 Performance:', metrics);
break;
}
}
} catch (error) {
console.log('Advanced operations failed:', error);
}
}
};
return (
<View style={{ flex: 1 }}>
<Pdf
ref={pdfRef}
source={{ uri: 'http://example.com/document.pdf' }}
onLoadComplete={(pages) => {
console.log(`Loaded ${pages} pages`);
handleAdvancedOperations();
}}
style={{ flex: 1 }}
/>
</View>

}
```
## 🚨 Expo Support
This package is not available in the [Expo Go](https://expo.dev/client) app. Learn how you can use this package in [Custom Dev Clients](https://docs.expo.dev/development/getting-started/) via the out-of-tree [Expo Config Plugin](https://github.com/expo/config-plugins/tree/master/packages/react-native-pdf). Example: [`with-pdf`](https://github.com/expo/examples/tree/master/with-pdf).
### FAQ
<details>
<summary>FAQ details</summary>
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`](https://github.com/wonday/react-native-pdf/issues/24) and [`#2`](https://github.com/wonday/react-native-pdf/issues/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`](https://github.com/wonday/react-native-pdf/issues/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`](https://stackoverflow.com/questions/54818098/cleartext-http-traffic-not-permitted)
Q4. why doesn't it work with react native expo?.
A4. Expo does not support native module. you can read more expo caveats [`here`](https://facebook.github.io/react-native/docs/getting-started.html#caveats)
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:
```js
const stats = await pdfRef.current.getJSIStats();
console.log('JSI Available:', stats.jsiEnabled);
```
**Q7. What if JSI is not available?**
A7: The package automatically falls back to standard bridge mode. You can check availability and handle accordingly:
```js
if (stats.jsiEnabled) {
// Use JSI methods
await pdfRef.current.renderPageWithJSI(1, 2.0);
} else {
// Use standard methods
pdfRef.current.setPage(1);
}
```

### Methods
* [setPage](#setPage)
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
```
