Typescript support in Svelte is one of the biggest problems with the framework I’ve encountered. We have a couple of production Svelte apps at my job and overall the frontend DX is excellent. However, not being able to use generically typed components is a big missing feature. We have a number of custom core components which work really well, but not being able to create a new component with something like MyTable = Table<User> feels like an oversight. Inside of the Table code we work around this shortcoming to appease tslint… Overall though regular .ts code works well. We use it for all our API definitions and networking layer, and it’s been 1000x better than our former version built with jinja/jQuery.
