Trip Planner

This project is an AI-powered travel planning app. It features a chatbot that helps users plan their trips and generates personalized itineraries using OpenAI's GPT models.

Project Structure

• backend/ — FastAPI backend (Python)
  • Handles chatbot and itinerary generation using OpenAI
  • Expects an .env file with your OpenAI API key
• frontend/ — React frontend (JavaScript)
  • User interface for chat, itinerary form, and results

Prerequisites

• Python 3.11+
• Node.js (v16 or newer recommended)
• npm (comes with Node.js)

Setup Instructions

1. Clone the repository and create a virtual environment

cd /Users/pratyushaduvvuri/Desktop/trip_planner
python -m venv venv
source venv/bin/activate

2. Install backend dependencies

cd backend
pip install -r requirements.txt

3. Set your OpenAI API key

Edit backend/.env and add:

OPENAI_API_KEY=sk-...  # Your OpenAI API key

4. Install Uvicorn (if not already installed)

pip install uvicorn

5. Start the backend server

From the backend directory:

uvicorn app.main:app --reload

The API will be available at http://localhost:8000

6. Install frontend dependencies

In a new terminal:

cd /Users/pratyushaduvvuri/Desktop/trip_planner/frontend
npm install

7. Start the frontend React app

npm start

The app will be available at http://localhost:3000

Troubleshooting

• If you see zsh: command not found: uvicorn, install it with pip install uvicorn in your virtual environment.
• Make sure your virtual environment is activated (source venv/bin/activate).
• If you see missing files in the frontend, ensure frontend/public/index.html exists (it should now).

Usage

• Open http://localhost:3000 in your browser.
• Use the chatbot to get travel ideas or go directly to the itinerary form to generate a trip plan.
