eslint-config-tc

library28.0.3jsnpmunverified

An ESLint shareable flat config for JavaScript projects, providing a comprehensive set of linting rules including style, import, Jest, and unicorn plugins. Current stable version is 28.0.3, requiring Node >=22, ESLint 10, and flat config. Key differentiators: integrates Prettier formatting, updates peer deps frequently, and drops legacy eslintrc support. Released irregularly with breaking changes on major bumps; v28 drops Node 20 and switches to flat config only.

Verified usage

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

Package is ESM-only since v28; CommonJS require() throws ERR_REQUIRE_ESM.

import tcConfig from 'eslint-config-tc';

No separate TS config; flat config works with @typescript-eslint/parser if added manually.

import tcConfig from 'eslint-config-tc'; // same as JS

Package does not export a CommonJS module; use ESM import.

// Not applicable; use flat config spread

Basic setup for ESLint flat config using eslint-config-tc with a rule override.

// eslint.config.mjs import tcConfig from 'eslint-config-tc'; export default [ ...tcConfig, { rules: { 'no-console': 'warn', }, }, ];
