🔥 Built a smarter regex constructor this weekend 🔥 The output of `.exec` is inferred from capturing groups and it supports *named* groups too! Would you use it if this was open source? #TypeScript

More features I could add: - check if your regex string is valid - automatically coerce number patterns like `[0-9]` to number - Add this to TS-Pattern?

Here is the code if you want to take a look (it's pretty complex) 👉

By the way, if you want to learn how I build this kind abstractions with smart type inference, you should read Type-Level TypeScript! It features a tom of free content + paid chapter for deep dive in more advanced concepts

Nice! I’ve been working on something similar for a while too, currently on third rewrite and almost done😂 two modes: infer all exact matched literal string or all possible matches as hint

It’s interesting to find that /t extends `${number}`, same goes to /r, /n…etc Any ideas? @mattpocockuk Thanks

@mattpocockuk That's definitely odd. Have you checked if there is an open issue about this?

that's some next-level type programming 😮👏

Yes! I teach how to do these kinds of things here (in case you don't already know)

🤯

I need this!!

Should I hit the npm publish button?
