Ever faced a situation where you desperately needed a queue, but traditional options were off the table? My team ran into this exact problem. After a lot of experimentation, we discovered a unique solution using Redis and BullMQ. This talk will share our journey – from the frustration of limited queueing options to building a highly scalable, lightning-fast system. We'll show you how we overcame the obstacles and achieved incredible results with Redis and BullMQ.

In TypeScript’s type system is more than just a tool for catching errors—it’s a way to solve complex problems with clean and reliable code. In this talk, we’ll dive into advanced TypeScript techniques like mapped types, conditional types, and generics to handle even the trickiest type challenges.You’ll see how these techniques can help you extract, transform, and validate data types while keeping your code simple and maintainable. These "TypeScript gymnastics" aren’t just for show—they’re practical skills that make your systems stronger and easier to work with.Come learn how to take full advantage of TypeScript’s flexibility and power to build solutions that are as smart as they are safe.

TypeScript Gymnastics: Why Are They So Powerful for You?

Typescript or not Typescript? More than ten years have passed since its birth, and many of us still struggle to understand and love it. It’s so simple but sometimes we don’t really know how it works.Well, it’s time to understand more and stop bypassing it with a simple any.Types, functions, literals, unions, intersections and so on: together, we will see all the notions that will lead you to start loving and using it to the fullest to ensure a more typologically secure future and perhaps not be hated by your future self.

Are you tired of wrestling with the limitations of REST APIs? ""Breaking REST Chains: A Fastify &amp; Mercurius Pathway to GraphQL Glory"" is your roadmap to a better way.Discover how GraphQL solves REST's shortcomings and how to implement it using Fastify and Mercurius. We'll cover: 1. REST limitations that hold back modern apps.2. GraphQL's game-changing features.3. Steps to transition using Fastify and Mercurius. Unlock the full potential of your APIs and break free from REST's constraints. Join us to learn, adapt, and elevate your API game.

Many Javascript developers have added typescript to their projects in the last few years. But how many of them are sure of their types at runtime? Can types be guaranteed on runtime too? Using Zod that can be realized! Let's see together how we can use Zod to improve the awareness of our code during its execution and prevent strange mistakes or a bad user experience.

In this talk, I want to show how we can use Zod to guarantee the type in a React Application at runtime. Environment variables, HTTP requests, forms and so on could create troubles in our applications, mainly if they contain unexpected types. Using Zod, we can create schemas to guarantee the types expected in our editor at runtime. In this way, we can react quickly when an environment variable misses or when someone changes the API contract without informing us. A small validation layer in our applications can prevent a bad user experience and notify us immediately, so we can fix the problem as soon as possible and mitigate the visualization of wrong data.

In this speech, I'll talk about the benefit of using GraphQL and show a small demo of an endpoint created with Fastify Mercurius and Prisma.
