What are react-native-pdf's main functionalities?
Load PDF from URL
This feature allows you to load a PDF document from a URL and display it within your React Native application. The code sample demonstrates how to load a PDF from a remote URL and handle events such as loading completion, page changes, and errors.
import React from 'react';
import { View, StyleSheet } from 'react-native';
import Pdf from 'react-native-pdf';
const PdfExample = () => {
const source = { uri: 'http://www.pdf995.com/samples/pdf.pdf', cache: true };
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);
}}
style={styles.pdf}
/>
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'flex-start',
alignItems: 'center',
marginTop: 25,
},
pdf: {
flex: 1,
width: '100%',
height: '100%',
},
});
export default PdfExample;
Load PDF from local file
This feature allows you to load a PDF document from a local file and display it within your React Native application. The code sample demonstrates how to load a PDF from a local file path and handle events such as loading completion, page changes, and errors.
import React from 'react';
import { View, StyleSheet } from 'react-native';
import Pdf from 'react-native-pdf';
const PdfExample = () => {
const source = require('./path/to/local/file.pdf');
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);
}}
style={styles.pdf}
/>
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'flex-start',
alignItems: 'center',
marginTop: 25,
},
pdf: {
flex: 1,
width: '100%',
height: '100%',
},
});
export default PdfExample;
Zoom and scroll
This feature allows users to zoom in and out of the PDF document and scroll through its pages. The code sample demonstrates how to enable zooming and scrolling functionalities in the PDF viewer.
import React from 'react';
import { View, StyleSheet } from 'react-native';
import Pdf from 'react-native-pdf';
const PdfExample = () => {
const source = { uri: 'http://www.pdf995.com/samples/pdf.pdf', cache: true };
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);
}}
style={styles.pdf}
scale={1.0}
minScale={1.0}
maxScale={3.0}
horizontal={false}
/>
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'flex-start',
alignItems: 'center',
marginTop: 25,

Installation
We use rn-fetch-blob
to handle file system access in this package,
So you should install react-native-pdf and rn-fetch-blob
npm install rn-fetch-blob --save
npm install react-native-pdf --save
react-native link rn-fetch-blob
react-native link react-native-pdf
FAQ
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 screen / the loading bar isn't progressing on IOS.
A3. Check your uri, if you hit a pdf that is hosted on a http
you will need to 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>
Q4. why doesn't it work with react native expo?.
A4. Expo does not support native module. you can read more expo caveats here
