react-native-pdf

A react native PDF view component (cross-platform support)

Feature

• read a PDF from url, blob, local file or asset and can cache it.
• display horizontally or vertically
• drag and zoom
• double tap for zoom
• support password protected pdf
• jump to a specific page in the pdf

Supported versions

We use react-native-blob-util to handle file system access in this package, So you should install react-native-pdf and react-native-blob-util

The table below shows the supported versions of React Native and react-native-blob-util for different versions of react-native-pdf.

| React Native | 0.4x - 0.56 | 0.57 | 0.60+ | 0.62+ | 0.62+ | | ------------------------- | --------------- | ------- | -------- | -------- | -------- | | react-native-pdf | 4.x.x - 5.0.x | 5.0.9+ | 6.0.0+ | 6.2.0+ | 6.4.0+ | | react-native-blob-util | | | | | 0.13.7+ |

🚨 Expo: This package is not available in the Expo Go app. Learn how you can use this package in Custom Dev Clients via the out-of-tree Expo Config Plugin. Example: with-pdf.

Installation

# Using npm
npm install react-native-pdf react-native-blob-util --save

# or using yarn:
yarn add react-native-pdf react-native-blob-util

Then follow the instructions for your platform to link react-native-pdf into your project:

iOS installation

React Native 0.60 and above

Run pod install in the ios directory. Linking is not required in React Native 0.60 and above.

React Native 0.59 and below

react-native link react-native-blob-util
react-native link react-native-pdf

Android installation

If you use RN 0.59.0 and above, please add following to your android/app/build.gradle**

android {

+    packagingOptions {
+       pickFirst 'lib/x86/libc++_shared.so'
+       pickFirst 'lib/x86_64/libjsc.so'
+       pickFirst 'lib/arm64-v8a/libjsc.so'
+       pickFirst 'lib/arm64-v8a/libc++_shared.so'
+       pickFirst 'lib/x86_64/libc++_shared.so'
+       pickFirst 'lib/armeabi-v7a/libc++_shared.so'
+     }

   }

React Native 0.59.0 and below

react-native link react-native-blob-util
react-native link react-native-pdf

Windows installation

• Open your solution in Visual Studio 2019 (eg. windows\yourapp.sln)
• Right-click Solution icon in Solution Explorer > Add > Existing Project...
• If running RNW 0.62: add node_modules\react-native-pdf\windows\RCTPdf\RCTPdf.vcxproj
• If running RNW 0.62: add node_modules\react-native-blob-util\windows\ReactNativeBlobUtil\ReactNativeBlobUtil.vcxproj
• Right-click main application project > Add > Reference...
• Select progress-view and in Solution Projects
  • If running 0.62, also select RCTPdf and ReactNativeBlobUtil
• In app pch.h add #include "winrt/RCTPdf.h"
  • If running 0.62, also select #include "winrt/ReactNativeBlobUtil.h"
• In App.cpp add PackageProviders().Append(winrt::progress_view::ReactPackageProvider()); before InitializeComponent();
  • If running RNW 0.62, also add PackageProviders().Append(winrt::RCTPdf::ReactPackageProvider()); and PackageProviders().Append(winrt::ReactNativeBlobUtil::ReactPackageProvider());

Bundling PDFs with the app

To add a test.pdf like in the example add:

<None Include="..\..\test.pdf">
  <DeploymentContent>true</DeploymentContent>
</None>

in the app .vcxproj file, before <None Include="packages.config" />.

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/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

*) requires building React Native from source with this patch

Methods

• 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
