"Definition for rule '@typescript/eslint/....' was not found" error happening in js, cjs and mjs files

[JaViLuMa]

So I am having an issue when overriding/replacing some default rules from XO when it comes to js, cjs and mjs files.

I have the following in my .xo-config.json file:

    "@typescript-eslint/object-curly-spacing": ["error", "always"],
    "@typescript-eslint/consistent-type-imports": "error",
    "@typescript-eslint/naming-convention": [
      "error",
      {
        "format": ["PascalCase"],
        "selector": ["typeLike", "enumMember"]
      },
      {
        "custom": {
          "match": false,
          "regex": "^I[A-Z]"
        },
        "format": ["PascalCase"],
        "selector": "interface"
      }
    ]

When I come to any of the js, cjs and mjs files, this is the error I get at the beginning of the file:

Definition for rule '@typescript-eslint/object-curly-spacing' was not found. (@typescript-eslint/object-curly-spacing)XO(@typescript-eslint/object-curly-spacing)
Definition for rule '@typescript-eslint/consistent-type-imports' was not found. (@typescript-eslint/consistent-type-imports)XO(@typescript-eslint/consistent-type-imports)
Definition for rule '@typescript-eslint/naming-convention' was not found. (@typescript-eslint/naming-convention)XO(@typescript-eslint/naming-convention)

Any reasons why does this happen?

+1 for @typescript-eslint/naming-convertion:

yes - xo applies the rules to every file, but in the case of a JS file in a typescript project, it may be better to use overrides to prevent it from trying to apply the TS rules to those files:

{
  "overrides":  [
    "files": "*.ts",
     "rules" {
       "@typescript-eslint/...": [...]
    }
  ]
}

This issues is definitely not closed. This is not a fix for the problem, that it is not possible to provide the correct configuration for this rule it in any manner. @spence-s

Your example is syntactically wrong. The error you pasted explicitly tells you that it is incorrect syntax and that you are missing the severity.

See my example below, it works just fine. - also the original issue was not about this rule, but about xo not finding @typescript-eslint rules which I gave a valid work around for...

This works totally fine for me - using the latest xo

module.exports = {
    prettier: true,
    parserOptions: {
        project: './tsconfig.xo.json',
    },
    rules: {
        '@typescript-eslint/naming-convention': ['error',{
                      selector: 'variable',
                      types: ['boolean'],
                      format: ['PascalCase'],
                      prefix: ['is', 'should', 'has', 'can', 'did', 'will'],
                  }],
             ],
    }
};

(actual file not shown, just the line that uses the rule)

const Test = true;

  src/server.ts:28:7
  ✖  28:7  Variable name Test must have one of the following prefixes: is, should, has, can, did, will  @typescript-eslint/naming-convention
  ✖  28:7  Test is assigned a value but never used.                                                     @typescript-eslint/no-unused-vars

Thanks for your reply, will try that out. Ok, my issues is solved too then. Thanks for your time. :)
