TRAI App

Demo code for TRAI: An AI-Driven Mobile Application to Reduce the Gap Between Triage and Care

This repository contains three main components:

• Backend: Built with Node.js, Express, and TypeScript, managing chat functionalities and config control like the triage note, patient history and the database via Prisma (using SQLite).
• LLM Service: A Python service that connects to a language model (Mistral AI or Claude) for processing.
• Frontend: A Flutter application that provides the user interface for the TRAI application.

Running the Entire Application

Follow these steps to run the complete application. It is recommended to execute each component in a separate terminal window.

1. Run the Backend

   • Navigate to the backend directory:

     cd backend

   • Follow the steps in the Backend README to install dependencies, apply migrations, generate the Prisma client, and start the server:

     npm install
     npx prisma migrate dev
     npx prisma generate
     cp .env.sample .env  # Configure your environment variables
     npm run debug

2. Run the LLM Service

   • Open a new terminal window and navigate to the llm_service directory:

     cd llm_service

   • Follow the steps in the LLM Service README to set up and run the service:

     python -m venv venv
     source venv/bin/activate  # (or use the Windows equivalent)
     cp .env.sample .env  # Update the API key in the .env file as needed
     pip install -r requirements.txt
     python app.py

3. Run the Frontend

   • Open another terminal window and navigate to the frontend directory:

     cd frontend

   • Ensure that Flutter is installed on your device. For installation help, refer to the Flutter installation guide.

   • Follow the steps in the Frontend README to install dependencies and launch the application:

     flutter pub get
     cp .env.sample dev.env
     flutter run lib/main_development.dart

Ensure that the backend is running first, then start the LLM service and the frontend simultaneously to allow the complete application to function correctly.
