The most loved frontend-framework Svelte has gained good TypeScript support over the last years and is capable to deliver a great developer experience - also within buisness applications. Unfortunately it is not that easy to find good documentation about all the TypeScript features Svelte offers. In my talk I want to show how to get started and go over some code examples. At the end I will reference a repository where more examples are available to dig deeper into this topic. Along the way I will also give some general TypeScript tipps that enable even stronger static type checks than probably most developers currently know.
