Cross-Origin Resource Sharing (CORS) Demystified

December 21, 2017  /  


In a recent presentation at the Kansas City Developer Conference, Spring Venture Group’s own Bill Parrott simplified the topic of sharing resources across domains. Bill shared his thoughts on CORS, how it works, and why it is a crucial part of the modern web.

How was giving this talk valuable for the people who attended KCDC?

As the web becomes increasingly complex and interconnected, CORS (Cross-Origin Resource Sharing) is playing a larger role in the web development process. However, even though CORS is used almost everywhere, its use is largely unclear, even to developers. As a result, when issues come up, there is a surprising lack of true understanding of how CORS works. My goal with the talk was to help shed light on something that is frequently misunderstood.

What do you enjoy about speaking/being involved in the developer community?

This was my first presentation at a large conference, but I have given smaller talks to developer groups at previous jobs. As someone who loves learning new things and figuring out how things work, I have always enjoyed attending developer conferences and networking with the community. Teaching is something that I have enjoyed for most of my life – I originally majored in Music Education in college before switching to Computer Science – and I have wanted for several years to try my hand at a conference speaking. Now, having done it once, I can say with certainty that I plan to do it again and again.

Congratulations to Bill for an intriguing presentation. We love seeing our team members in the wild, helping others in their given field.
