Change Request: track dependencies of eslint.config.js to invalidate cache & typescript support about eslint

[mdjermanovic]

The current implementation uses json-stable-stringify-without-jsonify to hash the config which is not appropriate for all given options (ie plugins, parsers, custom rules...) basically everything that is a function.

This problem is already solved by including metadata (name + version) of plugins and parsers in serialized configs (#16284).

https://eslint.org/docs/latest/extend/plugins#meta-data-in-plugins

https://eslint.org/docs/latest/extend/custom-parsers#meta-data-in-custom-parsers

For example, this is a serialized config for the eslint/eslint project:

      "tagNamePreference": {

Relevant part:

    "parser": "[email protected]",
    "parserOptions": {}
  },
  "plugins": [
    "@",
    "unicorn:[email protected]",
    "jsdoc",
    "@eslint-community/eslint-comments:@eslint-community/[email protected]",
    "n:[email protected]",
    "internal-rules"
  ],

We don't use the --cache flag, but if we did, every time a new version of e.g. espree or eslint-plugin-unicorn is used, the serialized configuration would change (for example, "parser": "[email protected]" would become "parser": "[email protected]") and thus invalidate the cache. We'd also add and maintain metadata for internal-rules (our internal plugin with custom rules).

At this moment, not all plugins export metadata (e.g., eslint-plugin-jsdoc, as can be seen in the serialized config above), but we expect that most plugins will soon.

thanks for the explanation, i will then fix it for all our plugins which haven't adopted yet.
