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.

How safe is TypeScript's type safety? How much can you trust your statically typed code? Can you even consider TypeScript's type system "strong"? In this talk, we look at situations where TypeScript fails badly and learn why things have to be that way. We talk about trade-offs, workarounds, and ultimately solutions for all the damn, terrible lies we tell ourselves when using TypeScript.

In this talk, we will explore the various issues encountered when building JavaScript CLIs, and demonstrate how TypeScript can address them and help us make our applications safer. By the end of this talk, you'll understand how to abstract runtime validations type behind easy-to-use interfaces, and have all the tools you need to bring those benefits into your own CLIs at little cost - whether they are open-source projects, or internal tools.

TypeScript goes beyond annotating syntax. We’ll explore how modern frameworks leverage type-safety at the project-level to empower better architecture, greater stability, and higher velocities.
