eslint-plugin-etc-misc

1.1.1 verified Sat May 09 auth: no javascript

An ESLint plugin that combines and extends the rules from eslint-plugin-etc and eslint-plugin-misc, providing a unified set of linting rules for TypeScript projects. Current stable version is v1.1.1, released in May 2026. The package is actively maintained with frequent releases (10+ versions in two months). Key differentiators: merges two popular rule sets into one plugin, includes TypeScript types, leverages ESLint flat config (v9+), and requires TypeScript 5+. Release cadence is weekly or more frequent. Alternative to installing separate plugins.

Common errors

error Error: Failed to load plugin 'etc-misc' declared in '...': Cannot find module 'eslint-plugin-etc-misc' ↓

cause Plugin not installed or name mismatch (e.g., using 'eslint-plugin-etc-misc' vs 'etc-misc')

fix

npm install eslint-plugin-etc-misc --save-dev and ensure correct name in config

error Configuration for rule 'etc-misc/no-unused-vars' is invalid: Value "error" is not accepted. Expected one of: "off", "warn", "error" ↓

cause Rule severity must be lowercase string

fix

Use '"error"' (lowercase) instead of '"Error"' or '"ERROR"'

error TypeError: plugin.configs is not iterable ↓

cause Flat config expects array, but default export is an object

fix

Use plugin.configs.recommended instead of spreading plugin directly

Warnings

breaking Requires ESLint v9+ with flat config; incompatible with legacy eslintrc ↓

fix Upgrade to ESLint v9 and migrate to flat config

breaking Minimum Node.js version 20.19.0 required since v1.1.0 ↓

fix Update Node.js to v20.19.0 or later

gotcha Default export is the plugin object with all rules, not a config array ↓

fix Use named import { configs } for recommended config, or spread the default export

deprecated Rule 'no-unused-vars' replaced by TypeScript-native version in v1.0.5 ↓

fix Use '@typescript-eslint/no-unused-vars' instead

npm install eslint-plugin-etc-misc

Quickstart

Shows how to set up the plugin with TypeScript project in ESLint flat config, including recommended config and custom rules.

// eslint.config.js
import plugin from 'eslint-plugin-etc-misc';
import tsParser from '@typescript-eslint/parser';
import tsPlugin from '@typescript-eslint/eslint-plugin';

export default [
  plugin.configs.recommended,
  {
    files: ['**/*.ts', '**/*.tsx'],
    languageOptions: {
      parser: tsParser,
      parserOptions: {
        project: './tsconfig.json',
      },
    },
    plugins: {
      '@typescript-eslint': tsPlugin,
    },
    rules: {
      'etc-misc/no-unused-vars': 'error',
      'etc-misc/consistent-type-imports': 'error',
    },
  },
];
