With the rise of remote work and mobile devices, the need for secure and reliable VPN connections has never been more pressing. As a developer, you might wonder: is it possible to create a mobile VPN application for Android using Ionic, Capacitor, and Vue 3? The answer is a resounding yes! In this article, we’ll take you on a journey to create a mobile VPN app that combines the power of Ionic, Capacitor, and Vue 3.
Prerequisites and Requirements
Before we dive into the development process, make sure you have the following prerequisites installed on your system:
Node.js
(version 14 or higher)Ionic CLI
(version 6 or higher)Capacitor
(version 3 or higher)Vue 3
(version 3.2 or higher)Android Studio
(version 4 or higher)JDK 11 or higher
Step 1: Setting Up the Project Structure
Create a new Ionic project using the following command:
ionic start my-vpn-app blank --type=vue
This will create a new project called my-vpn-app
with a blank template and Vue 3 as the framework.
Adding Capacitor to the Project
Next, add Capacitor to the project using the following command:
ionic integrations enable capacitor
This will install and configure Capacitor for your project.
Step 2: Creating the Mobile VPN Application
In this step, we’ll create the basic structure of our mobile VPN application.
Creating the VPN Service
Create a new file called vpn.service.ts
in the src/services
directory:
import { Injectable } from '@vue/composition-api';
@Injectable({
providedIn: 'root'
})
export class VpnService {
private vpn: any;
constructor() {}
async connect(vpnServer: string, username: string, password: string): Promise<boolean> {
// TO DO: Implement VPN connection logic here
return true;
}
async disconnect(): Promise<boolean> {
// TO DO: Implement VPN disconnection logic here
return true;
}
}
This service will handle the VPN connection and disconnection logic.
Creating the VPN Component
Create a new file called Vpn.vue
in the src/components
directory:
<template>
<div>
<h1>Mobile VPN App</h1>
<form @submit.prevent="connectVpn">
<label>VPN Server:</label>
<input type="text" v-model="vpnServer">
<br>
<label>Username:</label>
<input type="text" v-model="username">
<br>
<label>Password:</label>
<input type="password" v-model="password">
<br>
<button type="submit">Connect</button>
</form>
<p v-if="vpnConnected">VPN Connected!</p>
</div>
</template>
<script>
import { ref } from '@vue/composition-api';
import { VpnService } from '../services/vpn.service';
export default {
setup() {
const vpnServer = ref('');
const username = ref('');
const password = ref('');
const vpnConnected = ref(false);
const connectVpn = async () => {
try {
const vpnService = new VpnService();
const isConnected = await vpnService.connect(vpnServer.value, username.value, password.value);
if (isConnected) {
vpnConnected.value = true;
}
} catch (error) {
console.error(error);
}
};
return {
vpnServer,
username,
password,
vpnConnected,
connectVpn
};
}
}
</script>
This component will handle the VPN connection form and display the connection status.
Step 3: Implementing VPN Connection Logic
In this step, we’ll implement the VPN connection logic using the Android VPN API.
Adding Android VPN API Dependencies
Add the following dependencies to your android/app/src/main/java/com/example/myvpnapp/MainActivity.java
file:
import android.net.VpnService;
import android.Manifest;
public class MainActivity extends AppCompatActivity {
private static final String VPN_SERVICE_PACKAGE_NAME = "com.example.myvpnapp";
private static final String VPN_SERVICE_CLASS_NAME = "com.example.myvpnapp.VpnService";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// TO DO: Initialize VPN service
}
}
This will add the necessary dependencies for the Android VPN API.
Implementing VPN Connection Logic
Create a new file called VpnService.java
in the android/app/src/main/java/com/example/myvpnapp
directory:
public class VpnService extends VpnService {
private Thread vpnThread;
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TO DO: Implement VPN connection logic here
return START_STICKY;
}
@Override
public void onDestroy() {
// TO DO: Implement VPN disconnection logic here
super.onDestroy();
}
}
This service will handle the VPN connection and disconnection logic using the Android VPN API.
Step 4: Building and Running the Application
In this final step, we’ll build and run our mobile VPN application.
Building the Application
Run the following command to build the application:
ionic build --prod
This will build the application for production.
Running the Application
Run the following command to run the application on an Android device or emulator:
ionic capacitor run android
This will launch the application on the connected Android device or emulator.
Conclusion
And that’s it! You’ve successfully created a mobile VPN application using Ionic, Capacitor, and Vue 3. This application can connect to a VPN server and establish a secure connection using the Android VPN API.
Next Steps
While this article has provided a comprehensive guide to creating a mobile VPN application, there are several areas where you can improve and expand upon this application:
