Making your GitHub URLs shine with dynamic preview images

You know that feeling when you make your latest project on GitHub public and you’re ready to share it with the world? Or when you landed a PR that you’re so proud of, that you want the entire Twitterverse to hear about it?

We wanted to help you make those links stand out, and give people a visually interesting and informative preview of your hard work. So, we set about creating a framework and service for automatically generating social preview images for repositories and other resources on GitHub. Now when you share a link to a GitHub resource on a social media platform, you and your friends will see a beautiful preview image.

This talk will explain why we built this little service that now generates 2 million images every day, how the OpenGraph spec works, and more—helping you share your work in the best way possible.
