A Javascript interface for FYERS API.
📦 Node.js, 🌐 Web, 📜 Files, 📰 Docs.

FYERS is one of the cheapest online stock brokers in India, that offers trading in the equity (NSE, BSE), currency (NSE), and commodity segments (MCX). The objective of this package is to provide a cleaner interface to FYERS API. The http namespace provides the same interface as FYERS HTTP API. The websocket namespace provides the same interface as FYERS WebSocket API, along with parsing of binary market data. This allows you to recieve instant notifications of order update and market data. The top namespace (global functions, classes) provide a facade for the HTTP and the WebSocket APIs and provides additional utility functions, such as calculating charges.

Global functions associated with FYERS API, such as getPositions(), are stateless and accept Authorization as the first parameter. On the other hand, the Api class includes stateful functions which do not require the Authorization parameter (required while creating object). Note that this authorization can be obtained be performing login with loginStep1() and loginStep2().

The goals for the future include doing a thorough interface check, and possibly writing a CLI interface. Obtaining details of symbols, including images and more could be done as part of a separate package.

This package is available in both Node.js and Web formats. The web format is exposed as extra_fyers standalone variable and can be loaded from jsDelivr CDN.

Stability: Experimental.

const fyers = require('extra-fyers');

async function main() {
  var appId       = '****';  // app_id recieved after creating app
  var accessToken = '****';  // access_token recieved after login
  var api = new fyers.Api(appId, accessToken);

  // List equity and commodity fund limits.
  console.log(await api.getFunds());

  // List holdings.
  console.log(await api.getHoldings());

  // Place CNC market order for SBIN (equity) on NSE for 5 shares
  var id = await api.placeOrder({symbol: 'NSE:SBIN-EQ', quantity: 5});

  // List postions for today (should list NSE:SBIN-EQ-CNC).
  console.log(await api.getPositions());


  // Connect to Market data with WebSocket
  // and recieve real-time market quotes.
  await api.connectMarketData(quote => {
    console.log(quote);
  });
  // Choose which symbols you want to subscribe to.
  await api.subscribeMarketDepth(['NSE:SBIN-EQ']);

  // Connect to Order update with WebSocket
  // and recieve real-time order status updates.
  await api.connectOrderUpdate(order => {
    console.log(order);
  });
  // Subscribe to order status updates.
  await api.subscribeOrderUpdate();
}
main();
