The modern-day web application is a rich tapestry of data. It's dynamic, and it's personal. We expect that apps know who we are. We expect them to provide new and interesting content curated just for us. It's no surprise that this has led to an explosion in web technologies that embrace the ever-changing and personal nature of data, forgoing fully rendered pages in exchange for UI components and client-side data fetching.

In this talk, we're going to explore the ways that these paradigm shifts affect frontend developers, some technologies and tools that can help us navigate smoothly in this space, and some of the new opportunities this opens up for building fantastic user experiences.

We'll focus in on examples using React and GraphQL, but the concepts will apply to anyone who is building apps using components and dynamically fetched data. We'll dive into concepts like parallel loading states, components that can declare their data requirements, optimistic UI, error handling, and more.

Whether you've built apps like this before, or you are embarking on your first one, you'll come away with some concrete strategies for designing and developing modern web apps that your users (and your dev team!) will love.
