In this presentation, I will demonstrate how we leveraged the strengths of Scala and TypeScript to develop a collaborative text editor that meets the strictest standards for security, performance, and real-time collaboration.

Have you ever wondered what it takes to combine the power of Scala with the flexibility of TypeScript to create a secure, real-time collaborative text editor—similar to Google Docs, but built for high-security environments? Imagine a scenario where military teams need to simultaneously update critical text documents during a mission, while ensuring airtight security in air-gapped deployments.
In this presentation, I will demonstrate how we leveraged the strengths of Scala and TypeScript to develop a collaborative text editor that meets the strictest standards for security, performance, and real-time collaboration. I will dive deep into the technical architecture, powered by advanced operational transformation algorithms, which enables multi-user editing without conflicts. Additionally, I'll share how we layered robust security measures on top of the solution to ensure it meets military-grade standards, while maintaining seamless performance in isolated networks.
Scala Native can interact with C code and libraries, greatly expanding the library ecosystem beyond pure Scala offerings. Let's see the low level and high level tools that make it possible, talk through challenges of encoding various C concepts in Scala, and demonstrate what popular C libraries look like when used alongside idiomatic Scala code.
Do you like it when compiler generates the boring code for you? Fast, mundane, boring-but-error-prone code? Do you need to implement such a code generator yourself? Have you found out that Shapeless/Mirrors bend your brain a bit too much?
In this talk, we will walk through a concrete example of a boilerplate-heavy domain. By replacing common Scala 2 workarounds with Opaque Types, Extension Methods, Enums, and Union Types, we will demonstrate how to achieve a strictly typed, decoupled architecture without the noise.
This will be a live coding demonstration of Scala's newest feature set: capture checking.
