Intermediate TypeScript, v2

It's relatively easy to get started with TypeScript, but the learning curve becomes much steeper once things become more complex and abstract. This workshop teaches you how to leverage TypeScript's strengths to provide clarity in the face of complexity, while protecting your codebase and team from it's weaknesses.

Some Key Takeaways!

By participating along with us in the workshop, you'll learn:

  • Convert a real-world full stack Node+React app from JavaScript to TypeScript, using Mike's "minimally disruptive, maximally incremental" approach.
  • Create your own declaration files for an un-typed JavaScript library, as if you were about to add it to DefinitelyTyped
  • Learn how to convince your company/team to start using TypeScript, and 4 concrete risks you must keep an eye on in order to have a good outcome
  • Get hands-on experience with 3 of Mike's "Type Design Patterns" that you won't find anywhere else

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.
