Creating Your Own Image Format in the Browser

A presentation at JSConf Colombia in in Medellin, Antioquia, Colombia by Trent Willis

JavaScript and the web platform have evolved a lot in the past couple of years. In particular, Service Workers have given modern web applications tremendous power. They allow our apps to deliver content offline, send push notifications, and...create their own image formats? It’s a bit outlandish, but yes!

In this talk, we’ll go on a journey that starts with a dream and a Service Worker and ends with us having created our very own image format that works in the browser. Along the way, we’ll learn about some fantastic new web technologies, such as Streams and Web Cryptography, that are shipping in browsers today.
