Chapter 15: Supporting Embedded Content

Chapter 15, Supporting Embedded Content, is now finished! This chapter adds images and iframes, and covers all many related rendering, performance and security questions.

You might be surprised that iframes can be implemented in just one chapter’s worth of text and code. That’s because it builds on all of the powerful technology built up in prior chapters. I really enjoyed the way this chapter tied into almost every previous chapter’s code, leveraging it to make a complex feature come together quite quickly.

Images and iframes are almost the last core feature / architectural concept that we want to cover—we are nearly done with the book! In fact, unless we change plans, this looks like the last chapter with me as lead author. Honestly, I can’t believe how far this book has come, nor that it’s almost done. It’s been quite an adventure.

Thanks as always to readers, and our supporters on Patreon. Please continue to give us feedback and tell your friends all about it. And follow our blog and Mastodon (or Twitter if you need it) to hear about future updates, and participate in the GitHub Discussions with questions and answers for the community.
