node-app-store-connect-api VS tsdx

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]')

tsdx - Zero-config CLI for TypeScript package development

If you’re into TypeScript, I highly recommend https://tsdx.io . I’ve used it to create a package before and it’s so much easier

Thanks for the insight fellas. Aside question, I was thinking of bootstrapping the project with tsdx, but their last release was well over 2 years ago. Wondering if there are any alternative options for creating libraries?

NOTE: If your project uses TypeScript, I would suggest using tsdx instead.

Sadly, it's a bit dead. We switched to dts-cli fork, but tsup looks good too

I don't depend on the actual typescript docs much but thankfully in @types and in tons of repos there are examples of well written typescript code.

The amount of JS and TS out there is also a bit of a foot gun though so stick with heavily used/starred libs if you aren't sure.

One tool that helps a lot with developing libraries in typescript is TSDX[0] or its successor dts-cli[1] and there is a bunch of good stuff in awesesome-typescript[2].

Maybe library devving is harder?(more work?) with tyepscript but it is worth it for the end developer, especially if that end developer is you. If you aren't using your own libs then you're probably getting paid by someone else to make them or... idk.

We will use a TSDX library - this tool is something similar to create-react-app, but for creating components library. It allows as to initialize a project immediately with already set up bundler, Rollup with Typescript supporting, testing with Jest, code formatter, Prettier and Storybook.

May be you need to try https://tsdx.io/

So what is the ideal way to build TypeScript libraries? I've heard that tsdx https://tsdx.io/ is quite good

There’s tsdx. But I’d recommend using Vite and storybook-vite
