Why is yahoo-finance2 outputting a lot of unwanted text on my Mac Terminal?

Bug Report

Describe the bug

When getting the latest S&P 500 index data using the following node.js code, running on an Apple Mac Terminal:

var quote = await yahooFinance.quote("^GSPC")

I notice that yahoo-finance2 now outputs a lot of text on the Terminal. The text that it outputs is:

Fetching crumb and cookies from https://finance.yahoo.com/quote/AAPL...
fetch https://guce.yahoo.com/consent?brandType=nonEu&gcrumb=LvaAxoM&done=https%3A%2F%2Ffinance.yahoo.com%2Fquote%2FAAPL
fetch https://consent.yahoo.com/v2/collectConsent?sessionId=3_cc-session_4b45750a-1d2e-4a35-8971-0ac4f061bd1c
fetch https://consent.yahoo.com/v2/collectConsent?sessionId=3_cc-session_4b45750a-1d2e-4a35-8971-0ac4f061bd1c
fetch https://guce.yahoo.com/copyConsent?sessionId=3_cc-session_4b45750a-1d2e-4a35-8971-0ac4f061bd1c&lang=en-GB
Fetching crumb and cookies from https://finance.yahoo.com/quote/AAPL?guccounter=1...
Success. Cookie expires on Infinity
New crumb: 4h03r8BxYn3

How can I prevent this text output from appearing on the Terminal?

Minimal Reproduction

const yahooFinance = require('yahoo-finance2').default;
(async () => {
var quote = await yahooFinance.quote("^GSPC");
}) ()

Environment

Using node.js version v21.1.0.
npm version 10.2.0.

It should only call the cookie code once per library load, as it checks it's cookie jar each call to see if it has already pulled one. Currently the cookie jar is instance specific.

If you are running the library directly in the terminal, you are reloading the library each time making it so it fetches the cookies each time. To avoid this, you would want to set up your quote calls in a way where you keep the library instance running (like in a expressJS or ReactJS app).

Thanks for your reply.

Each time I run my node.js app which loads yahoo-finance2 via the line of code: const yahooFinance = require('yahoo-finance2').default; this text is printed out in the Mac's Terminal. In prior versions of yahoo-finance2, this text never appeared. Is there any way to suppress the text?

There was the option for custom logging that was integrated recently, you should be able to set that higher than debug to not show those I think (they're all logger.debug()). I haven't tried yet myself though

Thanks very much for that suggestion. Would you be able to give the exact line of code I can enter to try to suppress these unwanted lines of text on the console? I looked at the documentation, but could not work out what code to add.

Much appreciated.

There should be a { debug: false } feature. It's just annoying.

FWIW, this worked for me as of 2.11.3:

// See https://github.com/gadicc/node-yahoo-finance2/issues/778
// the error message
// "We expected a redirect to guce.yahoo.com, but got https://finance.yahoo.com/quote"
// _always_ gets written to console.error, instead of the configured logger.error
console.error = () => {};

yahooFinance.setGlobalConfig({
    // Disable all logging
    logger: {
        info: () => {},
        warn: () => {},
        debug: () => {},
        error: () => {}
    }
});

See:

• feat: Customisable logging #667
• Warning message expecting a redirect to guce.yahoo.com #778

(obviously, disabling console.error entirely is contrived, but I was building a contrived test app at the time so 🤷)

Thanks for the example, @zadjii-msft, which I think everyone will appreciate.

I've opened an umbrella issue to track future log changes when we get a chance to work on them (won't be soon, unfortunately).
