TypeScript for React Devs

What you'll actually walk away with

Most TypeScript-for-React tutorials stop at FC<Props> and call it a day. This course goes in the opposite direction: we skip the trivia and spend time on the type problems you actually run into.

By the end, you'll be able to:

• Write generic components that accept an items array and infer the item type from context
• Use discriminated unions to make invalid state unrepresentable
• Read and debug the gnarly Cannot assign to... errors from @types/react without googling
• Type an async hook that handles loading / error / data states without as any

Prerequisites

You've shipped a React app. You've touched TypeScript enough to know what interface is but have never written a generic type parameter on purpose.

Structure

Three lessons, ~60 minutes each. Videos run at 1x comfortably.
