🪙 Crypto Market Price(Top 20 Cryptocurrencies) App

A full-stack application that displays real-time cryptocurrency prices using the CoinGecko API.
Built with Flask (Python) on the backend and React on the frontend.

🔧 Tech Stack

  • Frontend: React, Axios, Tailwind CSS (optional)
  • Backend: Flask (Python 3.13+), Requests, Flask-CORS
  • API: CoinGecko Public API

🚀 Getting Started

📁 Project Structure

⚙️ Backend Setup (Flask)

  1. Navigate to backend folder:
cd backend
python -m venv venv
venv\Scripts\activate  # Windows
# OR
source venv/bin/activate  # macOS/Linux

pip install -r requirements.txt

pip install flask flask-cors requests

python app.py

By default, the server runs at: http://127.0.0.1:5004

  1. Navigate to frontend folder:
cd frontend
npm install
npm start

React app will run on: http://localhost:3000

🔄 API Endpoint:

GET /api/coins

🛡️ Notes:

** Make sure the backend is running before starting the frontend. ** If you face CORS issues, ensure flask-cors is installed and used in app.py:

from flask_cors import CORS CORS(app)

**The API may occasionally return a 429 Too Many Requests error. This is due to rate limiting by CoinGecko. You can cache results on the server to reduce API calls.

📦 Optional: requirements.txt

pip freeze > requirements.txt
