No runes outside svelte

[rChaoz]

Motivation

I don't think an explanation is needed - using runes outside Svelte files results in runtime errors/crashes, or at the very least doesn't work.

Description

No runes at all outside .svelte, .svelte.{js,ts} files (per configuration), except if imported, i.e. disallow global use of rune identifiers in regular files.

For now you need to add configs for parser.

It would be nice to add that to the recommended config, but that might be difficult since we don't know what JavaScript and TypeScript parsers our users are using.

I misunderstood what was written in this issue 😓

[ota-meshi]

Does the no-undef rule not work? I think $state will be reported as an undefined identifier in *.js files other than *.svelte.js.

Oh, Yes. We can see this error.

This seems to be an issue with the eslint.config.js settings, so I will close it. I will reopen it if the problem becomes clear with the provided REPL.
