How do I handle OAuth errors in Passport.js?

To handle OAuth errors in Passport.js, you can use the failureFlash option to provide error messages.

Can you give me an example of how to implement that?

Sure! You can set up your strategy like this: passport.use(new OAuth2Strategy({...}, function(accessToken, refreshToken, profile, done) {...})); and use passport.authenticate('oauth2', { failureFlash: true }) in your route.

What if I want to log the errors instead of flashing them?

You can log the errors in the callback function of your strategy. Just add a console log or a logging library to capture the error details.

Thanks! Is there a way to customize the error messages?

Yes, you can customize the messages by using the failureFlash option with a string or a function that returns a string based on the error.
