IEX API by Luxcium DEPRECATED

Luxcium : ™Scientia is lux principium

An unofficial SDK fork by Luxcium for using the free IEX API. You will be able to use this to get stock market information. This module is usable in Web Browsers, React Native, and NodeJS (though a polyfill/ponyfill for the fetch API is needed in NodeJS). Please make sure to open a GitHub issues for anything problematic to help us during the development phase of this project.

Features

  • Usable across all modern JS runtimes (with polyfills needed for fetch API where it's not available)
  • TypeScript support and accurate type definitions (with strict null checks)
  • Convenient object for getting API attribution information
  • Overridable API endpoint to allow for flexibility
  • Handles both JSON and CSV responses
  • Client that returns ES6 promises usable with async/await syntax

Breaking changes may happen on a daily basis at the minor version level util we get to version 1.x

Regarless please make sure to open a GitHub issue for anything problematic to help us during the development phase of this project.Considere our project is curently unstable(work-in-progress) until version 1.0

Installation

npm install --save iex-luxcium-api

Usage

In Web Browsers and React Native

import { IEXClient } from 'iex-luxcium-api';

const iex = new IEXClient(fetch);
iex.stockCompany('AAPL').then(company => console.log(company));

// {
//   symbol: "AAPL",
//   companyName: "Apple Inc.",
//   exchange: "Nasdaq Global Select",
//   industry: "Computer Hardware",
//   website: "http://www.apple.com",
//   description: "Apple Inc is designs, manufactures and markets mobile communication and media devices and personal computers, and sells a variety of related software, services, accessories, networking solutions and third-party digital content and applications.",
//   CEO: "Timothy D. Cook",
//   issueType: "cs",
//   sector: "Technology"
// }

In NodeJS

To use this in NodeJS and any other JS runtime that doesn't provide the fetch API, you will have to provide it through a polyfill or ponyfill. I recommend using fetch-ponyfill for this purpose, since it doesn't mess with the global context. You may find isomorphic-fetch easier to use, however.

npm install --save fetch-ponyfill
import fetchPonyfill from 'fetch-ponyfill';
import { IEXClient, StockSymbol } from 'iex-luxcium-api';

const fetcher = fetchPonyfill().fetch;
const iexClient = new IEXClient(fetcher);
iexClient.symbols().then((symbols: StockSymbol[]) => console.log(symbols[1000]));

//  {
//  symbol: 'BRC',
//  name: 'Brady Corporation',
//  date: '2019-03-08',
//  isEnabled: true,
//  type: 'cs',
//  iexId: '883'
//  }
npm install --save isomorphic-fetch
npm install --save-dev @types/isomorphic-fetch # If using TypeScript
import { CompanyResponse, IEXClient } from 'iex-luxcium-api';
import isomorphicFetch from 'isomorphic-fetch';

const iex = new IEXClient(isomorphicFetch);
iex.stockCompany('AAPL').then((company: CompanyResponse) => console.log(company));

// { symbol: 'AAPL',
//   companyName: 'Apple Inc.',
//   exchange: 'Nasdaq Global Select',
//   industry: 'Computer Hardware',
//   website: 'http://www.apple.com',
//   description:
//    'Apple Inc is designs, manufactures and markets mobile communication
//     and media devices and personal computers, and sells a variety of related
//     software, services, accessories, networking solutions and third-party digital content and applications.',
//   CEO: 'Timothy D. Cook',
//   issueType: 'cs',
//   sector: 'Technology',
//   tags:
//    [ 'Technology', 'Consumer Electronics', 'Computer Hardware' ] }

Subscribe to a topic (NodeJS Only)

The following code demostrates how to subscribe to an IEX reltime feed via NodeJS. IEX curretnly does not support subscribing from other platforms.

import { IEXClientRT } from 'iex-luxcium-api';

const iexRT = new IEXClientRT();
iexRT.observe('TWLO', 'MSFT').subscribe(update => console.log(update));

Or using promises

import { IEXClientRT } from 'iex-luxcium-api';
import { take, toArray } from 'rxjs/operator';

const iexRT = new IEXClientRT();
iexRT
  .observe('TWLO', 'MSFT')
  .pipe(
    take(5),
    toArray()
  )
  .toPromise()
  .then(values => console.log(values));

To Do

  • Define types and definitions for specific API operations:
    • Stocks
      • Quote
      • Chart
      • Batch Requests
      • Book
      • Open / Close
      • Previous
      • Company
      • Key Stats
      • Peers
      • Relevant
      • News
      • Financials
      • Earnings
      • Dividends
      • Splits
      • Logo
      • Price
      • Delayed Quote
      • List
      • Effective Spread
      • Volume by Venue
    • Reference Data
      • Symbols
    • IEX Market Data
      • TOPS
      • Last
      • HIST
      • DEEP
      • Book
      • Trades
      • System Event
      • Trading Status
      • Operational Halt Status
      • Short Sale Price Test Status
      • Security Event
      • Trade Break
      • Auction
    • IEX Stats
      • Intraday
      • Recent
      • Records
      • Historical Summary
      • Historical Daily
    • Markets
      • Market
  • Increase integration test coverage
  • Add documentation. In the meantime, the code is pretty well commented and should hopefully be easy to use thanks to type definitions.
  • Do runtime checks against each API endpoint with all possible inputs to discover possible enums, null responses,
  • Report discrepencies between docs and actual API responses to IEX
