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,
];

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 full rule coverage.
