Spend A Full Day Immersed in TypeScript with Mike North

Workshop Details

Getting comfortable with declaration files, advanced generics, transforming types, and some of the more tricky "how do I type this weird thing?" issues can be a serious challenge. Particularly when dealing with a tool like TypeScript that introduces breaking changes every three months, keeping yourself and your team unblocked means learning to diagnose some problems quickly, and apply effective fixes or workarounds.

In this advanced workshop, you'll grow from being a contributor to a TypeScript codebase, to being on the path to becoming "the neighborhood expert". We'll spend most of our time building a sizeable full stack app together, and discuss various challenges we'll encounter along the way.
