Lessons from Maintaining TypeScript Libraries

Maintaining widely-used JS libraries is already complicated, and TypeScript adds an additional set of challenges.

Join Redux maintainer Mark Erikson for a look at some of the unique problems TS library maintainers face, and how the Redux team has handled those problems. We'll cover:

- Tradeoffs of different ways to define TS types for a library
- How to target different versions of TS, and considerations for determining the supported version range
- Migrating existing JS libraries to TS
- Differences between writing "app" types and "library" types
- Managing and versioning public types APIs
- Tips and tricks used by types from the Redux libraries
- TS limitations and possible language-level improvements
