ellie VS typescript-strictly-typed

Sorry I'm not being helpful (in that, I dont have a solution for you) but it would be great if you could put this up as a working demo on Ellie (https://ellie-app.com/).

There is an online editor, named Ellie, to play with the language without the need to install anything on your machine. Ellie permits to install dependencies for your code, so you can prototype an entire project with it.

After that point I started looking into how Elm works from the web dev perspective with resources like Elm in Action and Frontend Masters courses (first working in ellie-app-for-elm-dev then upgrading to vite-elm-template).

I can still give you some pointers here. First I'd suggest you read the elm guide: https://guide.elm-lang.org/ It's the best place to start with elm. When you have a question about any specific subject, you should head to the slack, or ask a question on the elm discourse: https://discourse.elm-lang.org/ . The best way to get a useful answer, is to have a concrete question, and to prepare an example of what is wrong on Ellie (https://ellie-app.com). As such people can modify your Ellie to answer you.

You can paste it to Ellie for testing

https://builtwithelm.co/ lists some, but not sure what you consider large.

Not sure if you would categorize this as dev tool https://github.com/erkal/kite

And ellie certainly might be a dev-tool, but not a toy https://github.com/ellie-app/ellie

| There are important escape hatches that TS gives that make it unreliable

This is one way to mitigate those escape hatches:

But in my experience, you had better be starting a new project. They aren't joking when they say laying it on an existing codebase is a nightmare.
