This module is installed via npm:

npm install --save kiteconnect

var KiteConnect = require("kiteconnect").KiteConnect;

var kc = new KiteConnect("your_api_key");

kc.requestAccessToken("request_token", "api_secret")
	.then(function(response) {
		init();
	})
	.catch(function(err) {
		console.log(err.response);
	})

function init() {
	// Fetch equity margins.
	// You can have other api calls here.

	kc.margins("equity")
		.then(function(response) {
			// You got user's margin details.
		}).catch(function(err) {
			// Something went wrong.
		});
}

All API calls returns a promise which you can use to call methods like .then(...), .catch(...), and .finally(...).

kiteConnectApiCall
	.then(function(v) {
	    // On success
	})
	.catch(function(e) {
		// On rejected
	})
	.finally(function(e) {
		// On finish
	});

var KiteTicker = require("kiteconnect").KiteTicker;
var ticker = new KiteTicker(api_key, user_id, public_token);

ticker.connect();
ticker.on("tick", setTick);
ticker.on("connect", subscribe);

function setTick(ticks) {
	console.log("Ticks", ticks);
}

function subscribe() {
	var items = [738561];
	ticker.subscribe(items);
	ticker.setMode(ticker.modeFull, items);
}

In a typical web application where a new instance of views, controllers etc. are created per incoming HTTP request, you will need to initialise a new instance of Kite client per request as well. This is because each individual instance represents a single user that's authenticated, unlike an admin API where you may use one instance to manage many users.

Hence, in your web application, typically:

• You will initialise an instance of the Kite client
• Redirect the user to the login_url()
• At the redirect url endpoint, obtain the request_token from the query parameters
• Initialise a new instance of Kite client, use request_access_token() to obtain the access_token along with authenticated user data
• Store this response in a session and use the stored access_token and initialise instances of Kite client for subsequent API calls.
