More information can be found at https://www.compdf.com/

API

APIs are available on the API

Prerequisites

• A license is required for trial. Please contact our sales team to obtain a free trial license.
• npm or yarn
• ComPDFKit SDK => 2.0.1
• react-native => 0.60.0
• Android minSdkVersion of 21 or higher
• iOS 11 or higher

Installation

First, please follow the official React Native environment setup guide, configure iOS and Android environments, and create a React Native project. If you have already created a React Native project, you can skip directly to Integrate.

Creating a New Project

Let's create a simple app that integrates ComPDFKit for React Native.

1. In the terminal app, change the current working directory to the location you wish to save your project. In this example, we’ll use the ~/Documents/ directory:

   cd ~/Documents

1. Create the React Native project by running the following command:

   react-native init MyApp

1. In the terminal app, change the location of the current working directory inside the newly created project:

   cd MyApp

Integrate

You can integrate the SDK in two ways:

• Through ComPDFKit GitHub repo:

In MyApp folder, install react-native-compdfkit-pdf by calling:

  npm add github:ComPDFKit/react-native-compdfkit-pdf
  yarn install

or

  npm install github:ComPDFKit/react-native-compdfkit-pdf --save
  npm install

• Through ComPDFKit npm package:

In MyApp folder, install run the following commands:

  npm install react-native-compdfkit-pdf

Android

1. open android/app/src/main/AndroidManifest.xml , add Internet Permission and Storage Permission：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.compdfkit.flutter.example">

+    <uses-permission android:name="android.permission.INTERNET"/>
  
    <!-- Required to read and write documents from device storage -->
+    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
+    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

		<!-- Optional settings -->
+    <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />

    <application
+    android:requestLegacyExternalStorage="true"
        ...>
	...
    </application>
</manifest>

1. Copy the sample pdf file to the assets directory

1. Replace App.js (or App.tsx) with what is shown for Usage Example

2. Finally in the root project directory, run react-native run-android.

iOS

1. Open your project’s Podfile in a text editor:

open ios/Podfile

1. add the following line to the target 'MyApp' do ... end block:

target 'MyApp' do
    # ...
+    pod "ComPDFKit", podspec:'https://www.compdf.com/download/ios/cocoapods/xcframeworks/compdfkit/2.0.1.podspec'
+  pod "ComPDFKit_Tools", podspec:'https://www.compdf.com/download/ios/cocoapods/xcframeworks/compdfkit_tools/2.0.1.podspec'
    # ...
end

Note: If SSL network requests fail to download the ComPDFKit library when you run pod install, You can use the following method instead.

target 'MyApp' do
    # ...
+  pod 'ComPDFKit', :git => 'https://github.com/ComPDFKit/compdfkit-pdf-sdk-ios-swift.git', :tag => '2.0.1'
+  pod 'ComPDFKit_Tools', :git => 'https://github.com/ComPDFKit/compdfkit-pdf-sdk-ios-swift.git', :tag => '2.0.1'
    # ...
end

1. In the ios folder, run pod install.

2. Open your project’s Workspace in Xcode:

   open ios/PDFView_RN.xcworkspace

Make sure the deployment target is set to 10.0 or higher:

1. Add the PDF document you want to display to your application by dragging it into your project. On the dialog that’s displayed, select Finish to accept the default integration options. You can use "PDF_Document.pdf" as an example.

1. Replace App.js (or App.tsx) with what is shown for NPM or GitHub

2. Finally in the root project directory, run react-native run-ios.

Usage

Apply the License Key

ComPDFKit for React Native is a commercial SDK, which requires a license to grant developer permission to release their apps. Each license is only valid for one bundle ID or applicationId in development mode. Other flexible licensing options are also supported, please contact our marketing team to know more.

To initialize ComPDFKit using a license key, call either of the following before using any other ComPDFKit APIs or features:

• Online certification

import { ComPDFKit } from 'react-native-compdfkit-pdf';

type Props = {};
export default class App extends Component<Props> {
	...
  
  componentDidMount(){
    // Fill in your online license
    ComPDFKit.initialize('your android platform compdfkit license', 'your ios platform compdfkit license')
  }
  // ...
}

• Offline authentication

import { ComPDFKit } from 'react-native-compdfkit-pdf';

type Props = {};
export default class App extends Component<Props> {
	...
  
  componentDidMount(){
    // Fill in your offline license
    ComPDFKit.init_('your compdfkit license')
  }
  // ...
}

Usage Example

After installing from NPM or GitHub, replace App.tsx with the following code.

Make sure to follow the above steps to copy the sample document into your Android or iOS project.

The example includes a usage demonstration of selecting a PDF document from local file storage, which requires the use of the react-native-document-picker package. You can add this package as follows or remove the pickPDFFile function code from the example:

npm i react-native-document-picker

Here is the sample code for App.tsx:

• (Android) For content Uri:

document = 'content://...'

• (Android) For assets path:

document = "file:///android_asset/..."

• (iOS) For app bundle file path:

document = "document.pdf"

• (iOS) for URL path:

document = "file://xxxx/document.pdf"

Configuration

When rendering a PDF view using the ComPDFKit.openDocument method, you have the flexibility to enable or disable certain features or adjust default attribute values for PDF annotations, forms, and more through the CPDFConfiguration settings.

For your convenience, you can obtain default attribute values by using the ComPDFKit.getDefaultConfig({}) method.

The following example demonstrates the configuration settings for some aspects. For more detailed configuration options, refer to CONFIGURATION for further information.

1. Set the initial display mode and the list of available modes. The following code shows enabling only the viewer mode and annotations mode:

import { ComPDFKit, CPDFViewMode } from 'react-native-compdfkit-pdf';

var config = ComPDFKit.getDefaultConfig({
  modeConfig:{
    initialViewMode: CPDFViewMode.VIEWER,
    availableViewModes: [
      CPDFViewMode.VIEWER,
      CPDFViewMode.ANNOTATIONS
    ]
  }
})
ComPDFKit.openDocument(samplePDF, '', config)

1. Set the list of enabled annotation types and default annotation attribute values. For example, enable only highlight annotations and set the color and transparency for highlight annotations:

import { ComPDFKit, CPDFAnnotationType, CPDFConfigTool } from 'react-native-compdfkit-pdf';

var config = ComPDFKit.getDefaultConfig({
  annotationsConfig: {
    availableType: [
      CPDFAnnotationType.NOTE
    ],
    availableTools: [
      CPDFConfigTool.SETTING,
      CPDFConfigTool.UNDO,
      CPDFConfigTool.REDO,
    ],
    initAttribute: {
      note: {
        color: '#1460F3',
        alpha: 255
      }
    }
  }
})
ComPDFKit.openDocument(samplePDF, '', config)

1. Set the display mode and page flipping direction:

import { ComPDFKit, CPDFDisplayMode } from 'react-native-compdfkit-pdf';

var config = ComPDFKit.getDefaultConfig({
  readerViewConfig: {
    displayMode: CPDFDisplayMode.DOUBLE_PAGE,
    verticalMode: false
  }
})
ComPDFKit.openDocument(samplePDF, '', config)
