@reliquary/eslint-config

Shareable, framework-agnostic ESLint 9 flat config: TypeScript + stylistic + import-hygiene rules, safe for any TS/JS project (Node, browser, library).

Plain ESM with no build step; the plugins it needs are regular dependencies, so installing this package pulls everything in. For React projects, add the companion @reliquary/eslint-config-react layer — keeping it separate means non-React projects never install React/testing plugins.

Install

bun add -D @reliquary/eslint-config eslint
# or: npm i -D @reliquary/eslint-config eslint

eslint is a peer dependency — install the version your project uses (^9).

Usage

Create an eslint.config.mjs at your project root:

import config from '@reliquary/eslint-config';

export default config;

The default export is a flat-config array, so you can splice in your own overrides:

import base from '@reliquary/eslint-config';

export default [
  ...base,
  {
    rules: {
      '@stylistic/max-len': ['error', { code: 120 }],
    },
  },
];

For React, compose the React layer on top:

import base  from '@reliquary/eslint-config';
import react from '@reliquary/eslint-config-react';

export default [
  ...base,
  ...react,
];
