Usage

Sample Code

// ES5 Syntax using var and function declaration
const nseDataES5 = require('nse-data');

function fetchMarketStatusES5() {
    // Access marketStatus correctly through nseData
    nseDataES5.nseData.marketStatus(function(err, status) {
        if (err) {
            console.error('Error fetching market status (ES5):', err);
        } else {
            console.log('Market Status (ES5):', status);
        }
    });
}

fetchMarketStatusES5();

// CommonJS Syntax using require
const nseDataCJS = require('nse-data');

const fetchMarketStatusCJS = () => {
    nseDataCJS.nseData.marketStatus().then(status => {
        console.log('Market Status (CJS):', status);
    }).catch(err => {
        console.error('Error fetching market status (CJS):', err);
    });
};

fetchMarketStatusCJS();

// Anonymous Function using IIFE
(async () => {
    try {
        const status = await nseDataCJS.nseData.marketStatus();
        console.log('Market Status (Anonymous Function):', status);
    } catch (error) {
        console.error('Error fetching market status (Anonymous Function):', error);
    }
})();

// Top-Level Await (ES Module Context)
// Note: This will only work if the file is treated as an ES Module
import {nseData} from 'nse-data';
const status = await nseData.marketStatus();
console.log('Market Status (Top-Level Await):', status);
