        "node"
    ]
}

convert-require-to-import

node/no-missing-require has no sense when type=module in package.json. Check it out in 🐊Putout Editor.

{
    "overrides": [{
        "files": "test/*.js",
        "rules": {
-           "node/no-missing-require": "off"
+           "node/no-missing-import": "off"
        }
    }],
    "extends": [
        "plugin:node/recommended",
        "plugin:putout/recommended"
    ],
    "plugins": [
        "putout",
        "node"
    ]
};

remove-no-unpublished-require

node/remove-no-unpublished-require should be enabled, since this is a very useful rule, which shows what files should be add to .npmignore.

{
    "overrides": [{
        "files": "test/*.js",
        "rules": {
-           "node/no-unpublished-require": "off"
        }
    }],
    "extends": [
        "plugin:node/recommended",
        "plugin:putout/recommended"
    ],
    "plugins": [
        "putout",
        "node"
    ]
};

remove-no-unsupported-features

node/remove-no-unsupported-features is already disabled in eslint-plugin-putout.

{
    "overrides": [{
        "files": "test/*.js",
        "rules": {
-           "node/no-unpublished-require": "off"
        }
    }],
    "extends": [
        "plugin:node/recommended",
        "plugin:putout/recommended"
    ],
    "plugins": [
        "putout",
        "node"
    ]
};

remove-overrides-with-empty-rules

overrides with rules: {} has no sense. Check out in 🐊[Putout Editor]:

• remove empty rules;
• remove empty overrides;

Remove overrides with one element with empty rules:

{
-   "overrides": [{
-       "files": "test/*.js",
-       "rules": {
-       }
-   }],
    "extends": [
        "plugin:node/recommended",
        "plugin:putout/recommended"
    ],
    "plugins": [
        "putout",
        "node"
    ]
};

Or remove empty overrides:

{
-   "overrides": [],
    "extends": [
        "plugin:node/recommended",
        "plugin:putout/recommended"
    ],
    "plugins": [
        "putout",
        "node"
    ]
};

And ofcourse remove only elements with empty rules:

{
  "overrides": [{
-   "files": "test/*.js",
-   "rules": {
-   }
- }, {
    "files": "test/*.js",
    "rules": {
      "no-semi": "off"
    }
  }],
    "extends": [
      "plugin:node/recommended",
      "plugin:putout/recommended"
    ],
    "plugins": [
      "putout",
      "node"
    ]
};

convert-node-to-n

eslint-plugin-node is no longer supported. Better to use eslint-plugin-n.

{
    "extends": [
        "plugin:putout/safe+align",
-       "plugin:node/recommended"
+       "plugin:n/recommended"
    ],
    "plugins": [
        "putout",
-       "node"
+       "n"
    ]
}

remove-no-missing

node/remove-no-missing-require and node/remove-no-missing-import doesn't supports exports and already disabled by eslint-plugin-putout.

{
    "overrides": [{
        "files": "test/*.js",
        "rules": {
-           "node/no-missing-require": "off",
-           "node/no-missing-import": "off"
        }
    }],
    "extends": [
        "plugin:node/recommended",
        "plugin:putout/recommended"
    ],
    "plugins": [
        "putout",
        "node"
    ]
};
