Newsgram

Newsgram is a web application that fetches news articles from an API and displays them on a webpage. It includes a server-side component that handles news fetching and integrates caching using Redis to enhance performance.

Features

• Server-Side News Fetching: Handles fetching news from the API.
• Redis Caching: Caches news articles in Redis to reduce redundant API calls.
• Automatic Cache Expiration: Cached content is automatically expired after a set period (e.g., 60 minutes).
• Efficient API Usage: Reduces load on the external news API by using cached results when available.

Tech Stack

• Frontend: React
• Backend: Node.js/Express
• Caching: Redis

Installation

Clone the Repository

  git clone https://github.com/alokranjan609/NewsGram-Redis
  cd newsgram

Install Dependencies

  npm install

Set Up Redis

docker run -d --name redis-stack -p 6379:6379 -p 8001:8001 redis/redis-stack:latest

Environment Variables

• Create a .env file in the server directory with the following content:

GNEWS_API_KEY=your_news_api_key

Run the Application

• Start the Backend Server

cd server
npm start

• Start the Frontend Client

cd ../client
npm start

Access the Application

Open your browser and visit http://localhost:3000 to view the application.

How It Works

• Query Handling: The server checks if the query result is cached in Redis.
• Cache Hit: Returns cached data if available, improving response time.
• Cache Miss: Fetches data from the API, stores it in Redis, and returns the result.
• Cache Expiration: Cached data expires after a specified period to ensure fresh content.
