I'll dive into the internals of Nuxt to describe how we've built a TypeScript-first framework that is deeply integrated with the user's IDE and type checking setup to offer end-to-end full-stack type safety, hints for layouts, middleware and more, typed runtime configuration options and even typed routing. Plus, I'll highlight what I'm most excited about doing in the days to come and how TypeScript makes that possible not just for us but for any library author.

Creating a new Vue-based meta-framework from scratch with live coding.

Using real-life open-source examples, we'll explore the power of TypeScript to improve your users' experience. We'll cover best practices for library authors, as well as tips and tricks for how to take a library to the next level. This talk will cover: 
- how to leverage the type inference to provide help to your users; 
- using types to reduce the need and complexity of your documentation - for example, using function overloads, string literal types, and helper (no-op) functions; 
- setting up testing to ensure your library works (and your types do too!) with tools like tsd and expect-type; 
- treating types as an API and reducing breaking changes whilst shipping enhancements; 
- I'd draw on my experience with libraries like nuxt3, sanity-typed-queries and typed-vuex and show what we managed to do and what I'd do differently in future. 

Optimising developer experience with Nuxt 3 - a tour through the ways the new version of Nuxt will save time and make your life easier. We'll explore the new nitro-powered isomorphic fetch, dive into Nuxt 3's more powerful dynamic routing, and along the way tour a host of other features that will give you superpowers.
