Getting Started

Install the plugin:

npm install --save-dev eslint-plugin-etc-misc typescript

Enable one preset in your Flat Config:

import etcMisc from "eslint-plugin-etc-misc";

export default [etcMisc.configs.recommended];

Every exported preset is scoped to JavaScript and TypeScript file extensions, so it can be composed safely with ESLint language plugins for JSON, CSS, or other non-JavaScript languages.

Use minimal or recommended first, then move through stricter presets as your baseline stabilizes.

Alternative: manual scoped setup​

If you prefer to apply plugin rules inside your own file-scoped config object, spread the preset rules manually.

import tsParser from "@typescript-eslint/parser";
import etcMisc from "eslint-plugin-etc-misc";

export default [
 {
  files: ["**/*.{ts,tsx,mts,cts}"],
  languageOptions: {
   parser: tsParser,
   parserOptions: {
    ecmaVersion: "latest",
    // Enable only when using a type-aware preset.
    // projectService: true,
    sourceType: "module",
   },
  },
  plugins: {
   "etc-misc": etcMisc,
  },
  rules: {
   ...etcMisc.configs.recommended.rules,
  },
 },
];

Use this pattern when you only extend rules and want full control over parser setup per scope.

  1. Start with minimal if you want to defer the typescript/prefer-readonly* rules.
  2. Move to recommended for the full baseline.
  3. Promote to strict when you want the same rules to hard-fail.
  4. Move to strictTypeChecked once your lint config is fully type-aware.
  5. Adopt allStrict or all when you want every non-deprecated rule.

Use allStrictWithDeprecated or allWithDeprecated only as temporary migration presets when an existing configuration still needs deprecated rules.

Deprecated rules with same-plugin replacements remain available for explicit legacy configurations but are intentionally excluded from every preset.

See the Presets section in this sidebar for details and examples.
