# react-native-pdf [![npm](https://img.shields.io/npm/v/react-native-pdf.svg?style=flat-square)](https://www.npmjs.com/package/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`](https://github.com/RonRadtke/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](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). ### Installation ```bash # 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

iOS details

**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** ```bash react-native link react-native-blob-util react-native link react-native-pdf ```

### Android installation

Android details

**If you use RN 0.59.0 and above**, please add following to your android/app/build.gradle** ```diff 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** ```bash react-native link react-native-blob-util react-native link react-native-pdf ```

### Windows installation

Windows details - 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: ``` true ``` in the app `.vcxproj` file, before ``.

### 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`](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 : ``` NSAppTransportSecurity NSExceptionDomains yourserver.com NSIncludesSubdomains NSTemporaryExceptionAllowsInsecureHTTPLoads NSTemporaryExceptionMinimumTLSVersion TLSv1.1 ``` **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 ```
