library4.9.6jsnpmunverified

eslint-config-typed (v4.9.6) is a comprehensive, fully typed ESLint configuration package for the modern flat config system. It provides strongly-typed rule definitions, pre-configured setups for TypeScript, React, Preact, Vitest, Jest, and Playwright, and custom ESLint plugins (ts-restrictions, vitest-coding-style, react-coding-style). Requires ESLint >=9 and TypeScript >=5. Actively maintained with weekly releases. Differentiators: type-safe rule options, TypeScript config support, and built-in custom rules not found in other config packages.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

defineConfig

✓ import { defineConfig } from 'eslint-config-typed'

✗ const defineConfig = require('eslint-config-typed')

ESM-only since v4. Requires ESLint flat config. CommonJS require() will fail.

eslintConfigForTypeScript

✓ import { eslintConfigForTypeScript } from 'eslint-config-typed'

Function that returns a flat config array for TypeScript projects.

eslintConfigForVitest

✓ import { eslintConfigForVitest } from 'eslint-config-typed'

Pre-configured Vitest setup. Use eslintConfigForJest for Jest.

defineKnownRules

✓ import { defineKnownRules } from 'eslint-config-typed'

✗ import defineKnownRules from 'eslint-config-typed'

Named export only. Default export is not available in v4.

withDefaultOption

✓ import { withDefaultOption } from 'eslint-config-typed'

Utility to apply default options to a rule configuration.

Sets up a TypeScript project with Vitest using eslint-config-typed flat config.

// eslint.config.js import { defineConfig, eslintConfigForTypeScript, eslintConfigForVitest, } from 'eslint-config-typed'; export default defineConfig([ // TypeScript config for source files ...eslintConfigForTypeScript({ tsconfigRootDir: import.meta.dirname, tsconfig: 'tsconfig.json', files: ['src/**/*.ts', 'src/**/*.tsx'], }), // Vitest config for test files ...eslintConfigForVitest({ files: ['src/**/*.test.ts', 'src/**/*.spec.ts'], }), // Custom overrides { rules: { 'no-console': 'warn', }, }, ]);

Debug

Known issues

breakingPackage is ESM-only since v4. CommonJS require() will throw an error.

fix

Switch to ESM (type: "module" in package.json) and use import statements.

affects: >=4.0.0

breakingRequires ESLint 9+ flat config. Legacy .eslintrc format is not supported.

fix

Migrate to eslint.config.js with flat config. See ESLint migration guide.

affects: >=4.0.0

breakingRequires TypeScript >=5.0.0. Older TypeScript versions are not compatible.

fix

Upgrade TypeScript to version 5 or later.

affects: >=4.0.0

deprecatedSome configuration functions from v3 are replaced by new functions in v4. Old imports may break.

fix

Check the API reference and replace old function names.

affects: >=4.0.0

gotchaTypeScript config files (eslint.config.ts) require tsx or ts-node to execute. Ensure your Node version and loader support TypeScript.

fix

Use tsx (npm i -D tsx) and run eslint with node --loader tsx/esm.

affects: >=4.0.0

gotchaIf using import-x/no-unused-modules, you must enable the 'unusedImports' option in tsconfig.json or provide a separate config.

fix

Set compilerOptions.unusedLocals to false or configure import-x/no-unused-modules correctly.

affects: >=4.0.0

gotchaPerformance can degrade on large monorepos. Consider caching and ignoring node_modules.

fix

Add ignorePatterns: ['node_modules'] and use ESLint cache (--cache).

affects: >=4.0.0

Errors

Common errors & fixes

Cannot find module 'eslint-config-typed' or its corresponding type declarations.

Missing peer dependencies or incorrect module resolution.

fix

Install eslint-config-typed with its peer dependencies: npm add -D eslint eslint-config-typed typescript

Error: Failed to load config "eslint-config-typed" to extend from.

Using legacy eslintrc format instead of flat config.

fix

Create an eslint.config.js file and use flat config. Remove .eslintrc files.

TypeError: defineConfig is not a function

Using default import incorrectly; defineConfig is a named export.

fix

Use import { defineConfig } from 'eslint-config-typed' instead of import defineConfig from '...'

ERR_REQUIRE_ESM: require() of ES Module not supported.

Package is ESM-only, but you are using require().

fix

Switch to ESM by adding "type": "module" to package.json and use import declarations.
