Mobile Application System Specification

Overview

This document details the technical specifications for the mobile application, which will be developed using React Native. It outlines how the mobile application integrates with existing backend services, its data flow, and any mobile-specific technical requirements.

Technology Stack

  • Framework: React Native
  • Languages: JavaScript / TypeScript
  • Supported Platforms:
    • iOS (minimum version 15.1)
    • Android (minimum version 7.0 / API 24)

Architecture

The mobile application will follow a client-server architecture, interacting with the existing API Gateway and Authentication Service. It will consume RESTful APIs exposed by the API Gateway and potentially gRPC services from the Authentication Service.

Interaction with API Gateway

The mobile application will communicate with the API Gateway for all public-facing API calls. This includes:

  • User management (e.g., fetching user profiles, updating user data).
  • Admin functionalities (e.g., listing users, creating users, managing permissions).
  • Audit trail access.

Refer to the API Gateway REST API Contract for detailed API specifications.

Interaction with Authentication Service

Authentication and authorization will be handled by the existing Authentication Service. The mobile application will integrate with the authentication flows (e.g., SSO via Google Directory) and manage user sessions securely.

Refer to the Authentication Service gRPC API Contract for detailed authentication and authorization specifications.

Data Flow

  1. User Interaction: User initiates an action within the mobile application.
  2. API Request: The mobile application sends an authenticated request to the API Gateway.
  3. API Gateway Processing: The API Gateway routes the request to the appropriate backend service (e.g., Auth Service, User Service).
  4. Backend Service Response: The backend service processes the request and returns a response to the API Gateway.
  5. Mobile Application Update: The API Gateway forwards the response to the mobile application, which then updates its UI and state accordingly.

Mobile-Specific Technical Requirements

  • Offline Capabilities: (To be determined based on specific feature requirements) - Consider caching strategies for certain data to provide a seamless user experience during intermittent network connectivity.
  • Push Notifications: Integration with platform-specific push notification services (e.g., Apple Push Notification service, Firebase Cloud Messaging) for real-time alerts and updates.
  • Biometric Authentication: Support for fingerprint and facial recognition for enhanced login security and convenience.
  • Deep Linking: Ability to navigate to specific screens or content within the app via URLs.
  • Performance Optimization: Strategies for optimizing app startup time, UI responsiveness, and battery consumption.
  • Error Handling: Robust error handling and user feedback mechanisms for API failures and other issues.
  • Security: Implementation of secure data storage, communication, and authentication practices specific to mobile environments.
