Version 2.0.2
is the last stable release for the legacy UI.
The release can be found here: https://github.com/PDFTron/pdftron-react-native/releases/tag/legacy-ui.
-
First, follow the official getting started guide on setting up the React Native environment, setting up the iOS and Android environment, and creating a React Native project. The following steps will assume your app is created through
react-native init MyApp
. This guide also applies if you are using the TypeScript template. -
There are two ways to integrate the SDK:
-
In
MyApp
folder, installreact-native-pdftron
by calling:yarn add github:PDFTron/pdftron-react-native yarn install
or
npm install github:PDFTron/pdftron-react-native --save npm install
-
In
MyApp
folder, install run the following commands:yarn add @pdftron/react-native-pdf yarn install
or
npm install @pdftron/react-native-pdf npm install
-
-
Add the following in your
android/app/build.gradle
file:android { ndkVersion rootProject.ext.ndkVersion compileSdkVersion rootProject.ext.compileSdkVersion defaultConfig { applicationId "com.reactnativesample" minSdkVersion rootProject.ext.minSdkVersion targetSdkVersion rootProject.ext.targetSdkVersion versionCode 1 versionName "1.0" buildConfigField "boolean", "IS_NEW_ARCHITECTURE_ENABLED", isNewArchitectureEnabled().toString() + multiDexEnabled true + manifestPlaceholders = [pdftronLicenseKey:PDFTRON_LICENSE_KEY] } ... } ... dependencies { + implementation "androidx.multidex:multidex:2.0.1" ... }
-
In your
android/gradle.properties
file, add the following line:# Add the PDFTRON_LICENSE_KEY variable here. # For trial purposes leave it blank. # For production add a valid commercial license key. PDFTRON_LICENSE_KEY=
-
Add the following to your
android/app/src/main/AndroidManifest.xml
file:<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.myapp"> <uses-permission android:name="android.permission.INTERNET" /> <!-- Required to read and write documents from device storage --> + <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <!-- Required if you want to record audio annotations --> + <uses-permission android:name="android.permission.RECORD_AUDIO" /> <application ... + android:largeHeap="true" + android:usesCleartextTraffic="true"> <!-- Add license key in meta-data tag here. This should be inside the application tag. --> + <meta-data + android:name="pdftron_license_key" + android:value="${pdftronLicenseKey}"/> <activity ... - android:windowSoftInputMode="adjustResize" + android:windowSoftInputMode="adjustPan" + android:exported="true"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" /> </application> </manifest>
-
In your
android/app/src/main/java/com/myapp/MainApplication.java
file, changeApplication
toMultiDexApplication
:- import android.app.Application; + import androidx.multidex.MultiDexApplication; ... - public class MainApplication extends Application implements ReactApplication { + public class MainApplication extends MultiDexApplication implements ReactApplication {
-
Replace
App.js
(orApp.tsx
) with what is shown for NPM or GitHub -
Finally in the root project directory, run
react-native run-android
.
There is a new podspec file to use when integrating the PDFTron React Native Wrapper for iOS: https://pdftron.com/downloads/ios/react-native/latest.podspec
Please update your Podfile
accordingly.
-
Open
Podfile
in theios
folder, add the following line to thetarget 'MyApp' do ... end
block:target 'MyApp' do # ... pod 'PDFNet', podspec: 'https://pdftron.com/downloads/ios/react-native/latest.podspec' # ... end
-
In the
ios
folder, runpod install
. -
Replace
App.js
(orApp.tsx
) with what is shown for NPM or GitHub -
Finally in the root project directory, run
react-native run-ios
. -
(Optional) If you need a close button icon, you will need to add the PNG resources to
MyApp
as well, i.e.ic_close_black_24px
.
If you installed through GitHub, replace App.js
(or App.tsx
if you are using TypeScript) with the code below.
If you set your path variable to point to a local storage file,
then the PermissionsAndroid
component is required to ensure that storage permission is properly granted.
Within this example there are several sections of commented out code that work together to handle storage permissions.
Below the example are the types of file paths that are native to iOS or Android and accepted
by the DocumentView
component.

type Props = {};
export default class App extends Component<Props> {
// If you are using TypeScript, use `constructor(props: Props) {`
// Otherwise, use:
constructor(props) {
super(props);
// Uses the platform to determine if storage permisions have been automatically granted.
// The result of this check is placed in the component's state.
// this.state = {
// permissionGranted: Platform.OS === 'ios' ? true : false
// };
RNPdftron.initialize("Insert commercial license key here after purchase");
RNPdftron.enableJavaScript(true);
}
// Uses the platform to determine if storage permissions need to be requested.
// componentDidMount() {
// if (Platform.OS === 'android') {

} else {

}
};
render() {

PDFTron React Native introduced support for TypeScript in version 3.0.0. This update mainly benefits those who already use TypeScript in their applications. It also provides certain benefits to all customers, including those who use JavaScript without TypeScript.
To get access to TypeScript support, simply update your PDFTron React Native dependency to version 3.0.0 or higher.
For non-TypeScript users, updating your PDFTron React Native dependency to version 3.0.0 or higher will not automatically install TypeScript itself, and you can continue to use the library as before (without TypeScript support). If you currently do not use TypeScript itself in your project and would like to, see Adding TypeScript to an Existing Project.
Regardless of whether you use TypeScript, the following benefits are available:
- Proper API typings which can be used in tools such as IntelliSense. This offers insight into the data being passed without referring to the API documentation.
- Greater type safety and reliability due to the migration of source files from JavaScript to TypeScript.
- Updated Add an API guides for Android and iOS to offer step-by-step, TypeScript-supported examples on accessing properties, methods, and events. Contributors should be aware that PRs must now be made to the
dev
branch (see Contributing).
If you have questions, head to the FAQ's Integration section for Android and iOS.
If you are an existing TypeScript user, then the custom typings will be available to you simply by updating your PDFTron React Native dependency to version 3.0.0 or higher.
Note:
- TypeScript version 3.4.1+ is recommended. Although compilation still works with lower versions, typings may degrade to
any
. - Due to the introduction of proper typings to PDFTron's APIs, your compiler may now give warnings or errors about your usage of these APIs. In most cases these will not prevent your app from running but it is advised that you address them to take full advantage of TypeScript. It is particularly important to address them if you use TypeScript to emit files and have enabled
noEmitOnError
in yourtsconfig.json
.
