Getting Started

Note: Make sure you have completed the Set Up Your Environment guide before proceeding.

Step 1: Start Metro

First, you will need to run Metro, the JavaScript build tool for React Native.

To start the Metro dev server, run the following command from the root of your React Native project:

# Using npm
npm start

# OR using Yarn
yarn start

Step 2: Build and run your app

With Metro running, open a new terminal window/pane from the root of your React Native project, and use one of the following commands to build and run your Android or iOS app:

Android

# Using npm
npm run android

# OR using Yarn
yarn android

iOS

For iOS, remember to install CocoaPods dependencies (this only needs to be run on first clone or after updating native deps).

The first time you create a new project, run the Ruby bundler to install CocoaPods itself:

bundle install

Then, and every time you update your native dependencies, run:

bundle exec pod install

For more information, please visit CocoaPods Getting Started guide.

# Using npm
npm run ios

# OR using Yarn
yarn ios

If everything is set up correctly, you should see your new app running in the Android Emulator, iOS Simulator, or your connected device.

This is one way to run your app — you can also build it directly from Android Studio or Xcode.

Step 3: Modify your app

This project uses a base path to load the PDF file defined by BASE_PDF_PATH in the App.tsx file.

Note: Replace the value of BASE_PDF_PATH in App.tsx with a valid path to an existing file in your storage.

Example modification in App.tsx:

const BASE_PDF_PATH = 'file:///storage/emulated/0/Download/your_valid_file.pdf';

Native Module & Permissions

This project includes a native module that requests the MANAGE_EXTERNAL_STORAGE permission on Android. This permission is essential for granting the module extended access to storage, allowing it to load, render, and manipulate PDF files properly.
