yahoo-stock-prices

Node.js API to scrape stock prices from Yahoo Finance.

Installation

npm install yahoo-stock-prices

Usage

getCurrentData

Returns a promise which resolves with the current price of a stock, along with the currency of that stock.

Example

const data = await yahooStockPrices.getCurrentData('AAPL');
console.log(data); // { currency: 'USD', price: 132.05 }

getCurrentPrice

Returns a promise which resolves with only the current price, as a number.

Example

const price = await yahooStockPrices.getCurrentPrice('AAPL');
console.log(price); // 132.05

For backward compatibility with earlier versions you can also provide a callback as the second parameter, in which case no promise will be returned.

yahooStockPrices.getCurrentPrice('AAPL', (err, price) => {
    console.log(price); // 132.05
});
