The stock-market-india NPM package is your go-to tool for fetching live data from the Bombay National Stock Exchange (NSE). This comprehensive guide will help you navigate through its functionalities and get you started on leveraging stock market APIs with ease.

Installation Steps

Before diving into the API functionalities, you’ll need to install the necessary components. Let’s break it down step by step:

• Identify Application Location: Choose a location for your application directory. For this example, use home/user/your_app.
• Install Node.js: Ensure you have Node.js installed. You can download it from nodejs.org.
• Install Express: After finding your application directory, open the Command Prompt and type:

  npm install express

• Start Express Web Server: Navigate to your directory and run the command:

  node app.js 3000

  This will start your webserver on port 3000.

Using the API

The package offers a variety of API calls to access different stock market information. Here’s how you can utilize them:

• Get Market Status: Check whether the stock market is open or closed.

  http://localhost:3000/get_market_status

• Get Indices of NSE: Fetch all the indices including their changes and high/low values.

  http://localhost:3000/nse/get_indices

• Get Quotes: Retrieve quotes of all indexes in NSE.

  http://localhost:3000/nse/get_quotes

• Get Quote Info for a Specific Company: For example, if you want data about TCS.

  http://localhost:3000/nse/get_quote_info?companyName=TCS

• Get Top Gainers and Losers: Fetch the top 10 gainers or losers in the market.

  http://localhost:3000/nse/get_gainers

  http://localhost:3000/nse/get_losers

Understanding API Calls with an Analogy

Imagine you’re visiting a massive library filled with books (the stock market data). Each section (the API endpoints) of the library has a different collection of books (data points). You visit the “Market Status” section to check if the library is open or closed. Then, you wander over to the “Indices” section to see all the various topics covered in this library, including the highs and lows of each collection. You even stop by the “Company Quotes” section to get information about specific authors—just like retrieving stock information for TCS or WIPRO. Each API endpoint is like a different shelf in the library, neatly organizing the information you seek.

Troubleshooting Common Issues

While using the stock-market-india package, you might run into some common issues. Here are some troubleshooting tips:

• API Calls Fail from Browser: This can happen due to pre-flight requests made by the browser. To get around this, make the calls from your server application instead.
• Ensure Node.js and Express Are Properly Installed: Double-check your installation steps if you encounter issues starting the server.
• Insecure Headers: Some API responses may get blocked due to insecure headers. Make sure to configure your server to handle these situations.
