Welcome to the world of Smartsapp, a fully cross-platform messaging app that ensures your conversations are secure with End-to-End Encryption (E2EE). In this guide, we’ll walk you through the setup process, making it as user-friendly as possible. Grab your coding hat, and let’s get started!

Platform Support

Smartsapp supports a variety of platforms, ensuring you can chat from just about anywhere:

• Desktop: Windows, Linux, MacOS
• Mobile: Android, iOS
• Website: Accessible via any device with a browser

Back-end Setup

The backbone of Smartsapp is Firebase, which takes care of all your backend needs. Let’s break down the setup process:

Basic Setup

1. Go to the Firebase Console and create a new project named Smartsapp.
2. Enable Google Analytics for your project.

App Setup

1. Create an app for your project from the overview page.
2. Copy and paste the configurations in the required location as indicated in the respective app’s README.

Auth Setup

1. Navigate to the project Authentication section.
2. Select the Sign-in method tab.
3. Enable both Email/Password and Google Sign-In.

Firestore Setup

1. Go to the project Firestore section.
2. Create Firestore provisions and select a server closest to you.
3. Go to the Rules tab and apply the following rules:

rules_version = 2;
service cloud.firestore {
  match /databases/{database}/documents {
    match /contacts/{uid} {
      allow read, create, update: if request.auth != null;
    }
    match /keys/{uid} {
      allow read, create: if request.auth != null && request.auth.uid == uid;
    }
    match /messages/{msg} {
      allow read, create: if request.auth != null;
    }
    match /users/{uid} {
      allow read: if request.auth != null;
      allow create, update: if request.auth != null && request.auth.uid == uid;
    }
  }
}

4. In the Indexes tab, create the following index:

collection: messages,
fields: [users: Ascending, timestamp: Descending],
queryScope: Collection

Storage Setup

1. Access the project Storage section.
2. Create storage provisions based on your nearest server.
3. Under the rules tab, implement these rules:

rules_version = 2;
service firebase.storage {
  match /{bucket}/o {
    match /profilepic/{uid} {
      allow read: if request.auth != null;
      allow create, update: if request.auth != null &&
                            request.auth.uid == uid &&
                            request.resource.size <= 1024 * 1024 &&
                            request.resource.contentType.matches('image/.*');
    }
    match /media/{media} {
      allow read: if request.auth != null;
      allow create: if request.auth != null &&
                    request.resource.size <= 1024 * 1024 &&
                    request.resource.contentType.matches('image/.*');
    }
  }
}

Note

Running the E2EE Key Generator Server is essential for all platforms.

Troubleshooting Tips

If you encounter any issues during the setup process, consider these troubleshooting ideas:

• If you’re having trouble creating your Firebase project, ensure you’re logged into the correct Google account.
• Double-check the configuration settings pasted into your app for any typos or omissions.
• If authentication methods are not working, revisit the Auth Setup section and confirm that the settings have been saved properly.
• If Firestore rules are causing errors, test them with Firebase’s simulator to ensure they are configured correctly.
