In this article from the liblab blog, we're exploring ways to make your TypeScript-based SDK more maintainable. The focus is on managing API routes within the SDK. We'll be discussing how to alias types, statically define data structures, make routes and arguments more resistant to typos, use generics for code reuse, and tying it all together with our defined types. Some limitations of these tips are also mentioned, including avoiding using `any` keywords and dealing with type guards/generic functions that can get complex. Finally, we'll talk about how liblab's SDK generation tools can help avoid the need to develop an SDK altogether.
