An example ESLint configuration for typescript to be used with the VSCode ESLint plugin. It's built with airbnb-base, prettier, and most well known ESLint plugins. It took a long time to configure so I thought it should be shared for others to reuse.

.eslintrc.js

module.exports = {
  "parser": "@typescript-eslint/parser",
  "parserOptions": {
    "project": "./tsconfig.json"
  },
  "extends": [
    "eslint:recommended",
    "airbnb-base",
    "plugin:eslint-comments/recommended",
    "plugin:promise/recommended",
    "plugin:jest/recommended",
    "plugin:node/recommended",
    "plugin:unicorn/recommended",
    "plugin:sonarjs/recommended",
    "plugin:import/errors",
    "plugin:import/warnings",
    "plugin:import/typescript",
    "plugin:@typescript-eslint/recommended",
    // Disable rules from packages above that could interfere with prettier
    "prettier",
    // Add extra exclusions for plugins used
    "prettier/@typescript-eslint",
    "prettier/unicorn",
    // Turn on prettier rules
    "plugin:prettier/recommended",
    // Add security rules last to make sure they are not overridden
    "plugin:security/recommended"
  ],
  "env": {
    "node": true,
    "es6": true,
    "jest": true
  },
  "plugins": [
    "eslint-comments",
    "promise",
    "jest",
    "node",
    "import",
    "unicorn",
    "sonarjs",
    "prettier",
    "security",
    "optimize-regex",
    "no-loops",
    "@typescript-eslint"
  ],
  "rules": {
    // Allow explicit any for faster development
    "@typescript-eslint/no-explicit-any": "off",
    // allow implicit function return type for faster development
    "@typescript-eslint/explicit-function-return-type": "off",
    // Turn on optimize-regex plugin
    "optimize-regex/optimize-regex": "warn",
    // Turn on no-loops plugin
    "no-loops/no-loops": "error",
    // Allow _id because of Mongoose
    "no-underscore-dangle": ["error", { "allow": ["_id"] }],
    // Allow typescript style imports
    "node/no-unsupported-features/es-syntax": ["error", {
      "ignores": ["modules"]
    }],
    // Prettier already tries to keep code to 80 columns, but this rule attempts
    // to cover remaining cases.
    "max-len": ["error", {
      "code": 100,
      "ignoreStrings": true,
      "ignoreTemplateLiterals": true,
      "ignoreUrls": true
    }],
    // Allow disabling eslint rules for an entire file.
    // Useful for things like the logger module, where no-console is disabled.
    "eslint-comments/disable-enable-pair": ["error", {
      "allowWholeFile": true
    }]
  },
  "overrides": [{
    "files": "test/**/*.js",
    "rules": {
      // Needed to import supertest in test files
      "node/no-unpublished-require": "off"
    }
  }]
}

What is unique about this specific configuration? Any benefits?
