Installation

Install packages

npm install @doko/react-native-pdf-editor react-native-nitro-modules
# or
yarn add @doko/react-native-pdf-editor react-native-nitro-modules
# or
pnpm add @doko/react-native-pdf-editor react-native-nitro-modules

react-native-nitro-modules is required. This package is implemented as a Nitro Module, not a classic native module.

Enable the New Architecture

Your app must use React Native's New Architecture. Check your React Native version and project settings first. If your app still depends on the old bridge, this library will not load.

iOS

Run CocoaPods install from your app's iOS directory:

cd ios
pod install

The podspec downloads the PoDoFo xcframework release used by this library. If you change the package version or the PoDoFo version, run pod install again so the generated Nitro headers and Pods project stay in sync.

Android

Make sure your app's minSdkVersion is at least 26:

android {
  defaultConfig {
    minSdkVersion 26
  }
}

The Android package pulls the published io.github.doko-demo-doa:podofo-android artifact.

Expo apps

This is a native module, so Expo Go is not enough. Use a development build:

npx expo prebuild
npx expo run:ios
npx expo run:android

For Android, set android.minSdkVersion to 26 through expo-build-properties if needed.

Import paths

Editing, rendering, encryption, metadata, fields, annotations:

import { PdfDocument, PdfRenderer } from '@doko/react-native-pdf-editor';

Signing helpers:

import { signPdf, createSigner } from '@doko/react-native-pdf-editor/signing';

Verify installation

Create and save one PDF:

import { PdfDocument } from '@doko/react-native-pdf-editor';

const doc = PdfDocument.create();
const page = doc.createPage(612, 792);
const painter = page.createPainter();
const font = doc.getStandard14Font('Helvetica');

painter.setFont(font, 24);
painter.drawText('It works. The PDF has entered the chat.', 50, 700);
painter.finishDrawing();

await doc.save('/path/to/output.pdf');
