Additional ESLint's rules for Node.js

$ npm install --save-dev eslint eslint-plugin-node

• Requires Node.js >=6.0.0
• Requires ESLint >=4.19.1 (plugin:node/recommended preset requires >=5.0.0)

Note: It recommends a use of the "engines" field of package.json. The "engines" field is used by node/no-unsupported-features/* rules.

        "node/prefer-global/console": ["error", "always"],
        "node/prefer-global/process": ["error", "always"],
        "node/prefer-global/url-search-params": ["error", "always"],
        "node/prefer-global/url": ["error", "always"]
    }
}

• ⭐️ - the mark of recommended rules.
• ✒️ - the mark of fixable rules.

These rules have been deprecated in accordance with the deprecation policy, and replaced by newer rules:

This plugin provides plugin:node/recommended preset config. This preset config:

• enables the environment of ES2015 (ES6) and Node.js.
• enables rules which are given ⭐ in the above table.
• enables no-process-exit rule because the official document does not recommend a use of process.exit().
• adds {ecmaVersion: 2019} into parserOptions.
• adds Atomics and SharedArrayBuffer into globals.
• adds this plugin into plugins.

• Q: The no-missing-import / no-missing-require rules don't work with nested folders in SublimeLinter-eslint
• A: See context.getFilename() in rule returns relative path in the SublimeLinter-eslint FAQ.
