FYI, fkling/astexplorer#377.

Web demo would be cool.

Web demos for eslint are hard.

I started working on a universal eslint repl module a while ago (the idea being you'd self host it, pass it your plugin, and it would give you a UI that is AST explorer + rule checker in one that users can link to in issues).

However the problem is that a lot of eslint essentially requires access to the filesystem via fs (i.e. one use is to iterate through the list of rule source files - see requireindex in our plugin).

There are packages like eslint-web which are modified versions of eslint to work in the browser, but they lag behind and don't work as well as you might like.

For us to create a web demo, it would probably be a fair chunk of work.

@armano2 has pointed out that eslint-plugin-vue has this setup for their repo, so we can look to leveraging(/stealing) their work to make interactive docs happen:

https://mysticatea.github.io/eslint-plugin-es/rules/no-json-superset.html
https://mysticatea.github.io/vue-eslint-editor/

Note that even with this codebase as a starting point - this is still a non-trivial amount of work due to the need for build tooling and such.

I think it's not a steal :D

Also, https://mysticatea.github.io/vue-eslint-demo/ is an existing playground, which supports old typescript-eslint-parser. I think that it's not hard to fork that for this repository. I can work in this weekend.

I'm sorry, I'm not sure if I can work in this weekend because of the flu. 🤒

Looks like the reason for the initial issue has been resolved, as AST explorer added @typescript-eslint/parser to its list

A separate interactive playground is definitely a nice to have too :)
