Progressive Enhancement - What It Is and Isn’t, a Practical Introduction With Svelte
Progressive Enhancement is the philosophy of providing a basic, functional experience to everyone, regardless of device, and adding additional layers of interactivity and delight as they are supported. The last decade of web development, focusing on SPAs, where JavaScript is a hard requirement, have made this philosophy very difficult – how do we make websites that are fundamentally built with JavaScript accessible to users without it? This talk examines the philosophy behind Progressive Enhancement, then focuses on some concrete examples (including a dive into Svelte compiler output!) of how we can build functional, reliable, and usable experiences for all, adding delightful interactivity for those who can support it.
