React Advanced 2023

This Talk discusses opt-in design in web development, focusing on API design and understanding good defaults. Opt-in design allows developers to start with minimal tools and gradually add complexity as needed. The principles of opt-in design include finding the lowest common denominator, making complexity easy to add, and prioritizing the user experience. The Talk also explores the concept of opt-in design in React and Astro, as well as the comparison between React and Solid frameworks. Server rendering and streaming in React are highlighted, along with the importance of suspense boundaries for a better user experience.

Picking up a new technology, developers stick with defaults. It's a fact that every tool from JQuery to NextJS has needed to face. At their worst, defaults ship hundreds of wasted JS kilobytes for routing, state, and other baggage developers may never use. But at their best, defaults give us a simple baseline to start from, with a clear path to add the exact set of features our project demands. This is the magic of opt-in design. Let's see how smart defaults guide modern frontend tools from Astro to React Server Components, and why this new era reshapes your workflow, and performance metrics, for the better.

The Talk discusses forced optimization with Node and Deno, with Deno aiming to pursue the same goals in a more expansive and modern way. Deno has built-in support for NPM and enforces security constraints. It also has a key-value database called Deno KV, which will be a core part of the Deno 2 API. Deno Deploy is a serverless Edge Functions platform powered by FoundationDB, optimized for fast reading and ideal for building eCommerce sites or application servers at the edge. Deno 2.0 is coming soon with more features under development.

Deno 2.0 is imminent and it's bringing some big changes to the JavaScript runtime. In this talk, we'll introduce the new features including import maps, package.json auto-discovery, and bare specifiers. We'll discuss how these improvements will help address issues like duplicate dependencies and disappearing dependencies. Additionally, we'll delve into the built-in support for deno: specifiers on the deno.land/x registry and its role in providing a recommended path for publishing. Come learn about how these updates will shape the future of the JavaScript ecosystem and improve backwards compatibility with Node applications.
