iexcloud_api_wrapper

A Typescript wrapper for the new iexcloud market data API from IEX Group Inc. All data is returned as Promises for asynchronous data requests.

A complementary R package is also availiable.

Usage

• See USAGE.md file for complete interface definition and call signitures

Use the npm cli to install as a dependancy into your project

npm install --save git+https://git@github.com/schardtbc/iexcloud_api_wrapper

// OR

npm i iexcloud_api_wrapper

then in your .env file add the following keys

IEXCLOUD_API_VERSION = "stable"
IEXCLOUD_PUBLIC_KEY = "pk_..."
IEXCLOUD_SECRET_KEY = "sk_..."

# use the pk and sk obtained from your iexcloud account
# make sure the .env file is in your .gitignore file
# do not hard code the keys into your application code
# do not upload the keys to github.
# you can easily change the keys if they become compromised

To test that everything installed correctly and the .env file is properly setup you can use the following or similar code

// reminder: this is an async interface ...it's promises all the way down

const  iex = require( 'iexcloud_api_wrapper' )

const quote = async (sym) => {
    const quoteData = await iex.quote(sym);
    // do something with returned quote data
    console.log(quoteData)
};

quote("WDC");
