react-native link react-native-simple-openvpn

Android

Add the following to android/settings.gradle :

rootProject.name = 'example'
+ include ':vpnLib'
+ project(':vpnLib').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-simple-openvpn/vpnLib')
apply from: file("../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesSettingsGradle(settings)
include ':app'

Import jniLibs

Due to file size limitations, jniLibs are too big to be published on npm. Use the assets on GitHub Releases instead

Download and unzip the resources you need for the corresponding architecture, and put them in android/app/src/main/jniLibs (create a new jniLibs folder if you don't have one)

iOS

If using CocoaPods, run it in the ios/ directory

pod install

See iOS Guide for iOS side Network Extension configuration and OpenVPN integration

Disable VPN connection when app is terminated in iOS

Add the following to your project's AppDelegate.m :

+ #import "RNSimpleOpenvpn.h"

@implementation AppDelegate

// ...

+ - (void)applicationWillTerminate:(UIApplication *)application
+ {
+   [RNSimpleOpenvpn dispose];
+ }

@end

Please make sure the Header Search Paths of Build Settings contain the following paths:

$(SRCROOT)/../node_modules/react-native-simple-openvpn/ios

Or, if using CocoaPods, the following paths should be automatically included there:

"${PODS_ROOT}/Headers/Public/react-native-simple-openvpn"

Usage

import React, { useEffect } from 'react';
import { Platform } from 'react-native';
import RNSimpleOpenvpn, { addVpnStateListener, removeVpnStateListener } from 'react-native-simple-openvpn';

const isIPhone = Platform.OS === 'ios';

const App = () => {
  useEffect(() => {
    async function observeVpn() {
      if (isIPhone) {
        await RNSimpleOpenvpn.observeState();
      }

      addVpnStateListener((e) => {
        // ...
      });
    }

    observeVpn();

    return async () => {
      if (isIPhone) {
        await RNSimpleOpenvpn.stopObserveState();
      }

      removeVpnStateListener();
    };
  });

  async function startOvpn() {
    try {
      await RNSimpleOpenvpn.connect({
        remoteAddress: '192.168.1.1 3000',
        ovpnFileName: 'client',
        assetsPath: 'ovpn/',
        providerBundleIdentifier: 'com.example.RNSimpleOvpnTest.NEOpenVPN',
        localizedDescription: 'RNSimpleOvpn',
      });
    } catch (error) {
      // ...
    }
  }

  async function stopOvpn() {
    try {
      await RNSimpleOpenvpn.disconnect();
    } catch (error) {
      // ...
    }
  }

  function printVpnState() {
    console.log(JSON.stringify(RNSimpleOpenvpn.VpnState, undefined, 2));
