Guarding your IO Boundaries
At the boundaries of our applications, a lot of bad things can happen. Users supply all kinds of invalid or malicious input, other services may or may not return what their documentation promises, little Bobby Tables is sneaking around the corner. How do we cope?
In this talk, we’re going to look at concepts for guarding IO boundaries, use the example of the io-ts library to see what TypeScript can (and did!) learn from Haskell.

While spending time there on domain specific languages and building compilers, he discovered his love for functional languages and expressive type systems. With Haskell, Franz found a robust and elegant language to express himself, which he uses for his own personal tooling as well as a thinking tool. At TNG, he currently works on high-throughput ingestion of real-time data for a client’s Big Data platform.
