Like many here, I love typescript for library writing, at least internally. I've not made any big npm packages, so not sure how that would do, but I imagine I'd like it a lot too. What I hate is getting the build system set up to generate the right combination of .js/.d.ts files to work with the build system of whatever I'm using it in, particularly for libraries that use any form of preact/tsx files. I must be seriously missing something, but after 5 years as a node/react developer I still suck at making build pipelines for new projects.
