node-app-store-connect-api VS awesome-typescript

Here's a perfect example. I maintain a simple Node library designed to connect to Apple's App Store Connect API. https://github.com/dfabulich/node-app-store-connect-api

It accepts, as a parameter, an URL for Apple's REST API. My library handles authentication, and returns the parsed JSON result, with a handful of tweaks to make the API more usable in JavaScript.

Depending on which URL you request, you'll get different result object back. You could get a single object in response, or an array of objects, and the type of returned objects is different for each URL type.

How would you add TypeScript types to this API? Well, Apple provides an OpenAPI documentation of all of their URLs, which I could use to autogenerate types, but then, how would I handle all of those types in response to the user's string input?

Well, it turns out that TypeScript is so amazingly fancy that you can write very clever code to parse strings at compile time, extracting parameter types etc. from string literal types. https://lihautan.com/extract-parameters-type-from-string-lit...

The documentation explains how an API like this:

   app.get('/purchase/[shopid]/[itemid]/args/[...args]')

This could be a good learning resource, a collection of client & server-side TypeScript projects.
