Advanced Union Types in TypeScript

When programming how often do you have a variable that could have more than one possible type or structure?

It could be more often than you think!

A simple example is a variable that either holds data or does not (e.g. a nullable type).

A more advanced example is the status of an API call, which could be:

• ‘Loading’

• ‘Success’ (with a API result data structure)

• ‘Error’ (with an Error detail data structure)

A type that can have more than one type of structure is a Union Type.

What’s the best way to handle union types? How can use union types in a TypeScript to ensure strict type safety thus giving us a stronger guarantee that our code is correct?

This talk will introduce Union Types, explain the building blocks that are required to work efficiently and safely with unions, and then introduce a couple of libraries which provide us with convenience and consistency when declaring and using union types.

An (intended) side-effect of this talk might the planting of a seed of interest in the world of Functional Programming (although union types are perfectly valid outside of this paradigm).

Wayne is a co-founder and developer at Lambda IT with a particular interest in exploring programming paradigms which assist in ensuring code quality.

10 things every Angular Developer should know about zone.js

Zone.js is a library which is used in Angular to handle change detection. Most of the time it works really well - however if problems with zone.js occur, dealing with them can be a really frustrating experience. In this talk I want to share helpful things that I learned while deep-diving into zone.js and show you some problems you can run into and how to deal with them.
