Go Stock Tracker

Project Overview
`Go Stock Tracker` is a Go-based application designed to track and display stock market data in real-time. Utilizing the Gin web framework for routing and WebSocket for real-time communication, this application fetches stock data from an external API and presents updated information at regular intervals.

Features

• Real-time stock data tracking through WebSocket.
• Efficient web routing using Gin framework.
• Periodic updates of stock data at configurable intervals.
• Fetches data from external stock market APIs.
• Scalable architecture suitable for expanding to multiple stock symbols.

Getting Started

Prerequisites

• Go (1.x or later)
• External API key for stock data (e.g., Alpha Vantage)
• Git

Installation

1. Clone the Repository

   git clone https://github.com/your-username/go-stock-tracker.git

   API_KEY=<Your_Alpha_Vantage_API_Key>

go run app.go

Testing WebSocket Endpoint with Postman

Postman allows you to test WebSocket connections and send messages. Here's how you can test the /ws WebSocket endpoint:

1. Open Postman

2. Create a New WebSocket Request

   • Click on the New button.
   • Select WebSocket Request.

3. Configure the WebSocket URL

   • Enter the WebSocket URL in the format: ws://localhost:8080/ws (adjust the domain and port as per your server configuration).

4. Connect to the WebSocket

   • Click Connect to establish a WebSocket connection.

5. Send a Message

   • To request stock data, send a JSON message in the following format:

     {
       "action": "getStock",
       "ticker": "YOUR_STOCK_TICKER"
     }

   • Replace YOUR_STOCK_TICKER with the desired stock symbol (e.g., IBM or AAPL).

6. Receive Updates

   • After sending the message, you should receive periodic updates with the latest stock data.
   • The updates will appear in the Messages section of Postman.

7. Close the Connection

   • Once done, you can close the WebSocket connection by clicking the Disconnect button.

Note: Ensure your Go Stock Tracker application is running before testing with Postman.

Note:

• I have removed the sections commented out with <!-- --> as they might be related to features not currently implemented.
• The WebSocket section is now more focused on the real-time aspect of your application.
• Remember to replace https://github.com/your-username/go-stock-tracker.git with your actual repository URL.
• Ensure that the .env file and your API key are appropriately configured as per your project setup.
