Cross-Device Sync Module Documentation

Real-Time Mirroring

Ensures instantaneous synchronization of chat messages and notifications across all user devices, providing a seamless experience regardless of the device being used.

Offline Handling

Manages scenarios where one or more devices are offline by storing data locally and syncing once connectivity is restored, ensuring no data loss or delay in updates.

Conflict Resolution

Addresses simultaneous edits on multiple devices through intelligent conflict detection and resolution mechanisms, such as timestamp-based decisions to maintain data integrity.

Push Notifications

Sends instant alerts about new messages or updates even when the app isn’t open, enhancing user engagement and timely information delivery.

Device Registration & Management

Allows users to add or remove devices associated with their account, ensuring security and efficient management of synced devices.

Data Encryption & Security

Encrypts data both in transit and at rest to protect against unauthorized access, safeguarding user communications and privacy.

Cross-Platform Compatibility

Ensures the module works seamlessly across various operating systems (iOS, Android, Windows, macOS) to deliver a consistent experience across all platforms.

User Privacy & Anonymity

Respects user preferences regarding data sharing and ensures that interactions remain private, with options for anonymous usage where applicable.

Step-by-Step Explanation:

1. Device Registration Endpoint (FastAPI):

   • This endpoint allows devices to register with the system, enabling synchronization across all user devices.
   • It uses a Pydantic model for input validation.

2. React UI Component:

   • A simple form component that enables users to add device identifiers and sends them to the FastAPI endpoint.
   • Uses React state management for handling form inputs and submission.

3. Pydantic Data Schema:

   • Defines the structure of device information, ensuring consistency in data handling across both frontend and backend.

Code Samples:

FastAPI Endpoint:

from fastapi import APIRouter, Depends, HTTPException
from typing import List
from pydantic import BaseModel

router = APIRouter()

class DeviceInfo(BaseModel):
    user_id: int
    devices: List[str]

@router.post("/api/devices")
async def register_devices(
    device_info: DeviceInfo
):
    # Here you would implement the logic to store the devices and user ID
    return {"message": "Devices registered successfully"}

React UI Snippet:

import React from 'react';
import { useState } from 'react';

const DeviceRegistration = () => {
  const [deviceId, setDeviceId] = useState('');
  const [deviceList, setDeviceList] = useState<string[]>([]);

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    if (!deviceId.trim()) return;
    
    const newDevices = [...deviceList, deviceId];
    setDeviceList(newDevices);
    
    try {
      await fetch('/api/devices', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify({
          user_id: 1,
          devices: newDevices
        })
      });
    } catch (error) {
      console.error('Error:', error);
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <input
        type="text"
        value={deviceId}
        onChange={(e) => setDeviceId(e.target.value)}
        placeholder="Enter device ID"
      />
      <button type="submit">Register Device</button>
    </form>
  );
};

export default DeviceRegistration;

Pydantic Data Schema:

from pydantic import BaseModel

class DeviceInfo(BaseModel):
    user_id: int
    devices: List[str]
    
# Example usage:
device_info = DeviceInfo(user_id=1, devices=["device_1", "device_2"])
print(device_info.user_id)  # Output: 1
print(device_info.devices)   # Output: ["device_1", "device_2"]

These code samples illustrate the basic implementation of cross-device synchronization functionality.
