I am currently working on a web application and I am in the process of developing a feedback form widget that users can easily embed on their websites. The data submitted through this widget will be securely stored within my web application. One important feature I would like to incorporate is user authentication, where individuals need to login using either my application's credentials or through a social media account such as Facebook before submitting any information.
This is quite new territory for me as I've never implemented something similar before. I'm not very familiar with raw javascript and my concern with using jQuery is the potential conflict it may create with the client's existing page structure. Additionally, I am curious about how to handle cross domain requests in this scenario.
It's worth noting that the initial version of my widget should appear in a popup style interface.
Thank you in advance for your assistance with this matter.
