@cogs/eslint-config

Shared flat ESLint (v9+) configuration for the catesworks fleet. Exports a single createConfig factory that returns an array of flat config objects covering base JS/TS rules (typed via typescript-eslint projectService), import hygiene (eslint-plugin-import + eslint-import-resolver-typescript), React + hooks + JSX a11y, TanStack Query, MD/MDX linting, Jest and Testing Library rules for test files, and Prettier conflict-disabling — so every repo lints the same way without copy-pasting an eslint.config.mjs.

Install

pnpm add -D @cogs/eslint-config eslint

Usage

In your repo's eslint.config.mjs:

import { createConfig } from '@cogs/eslint-config'

export default createConfig({
  tsconfigRootDir: import.meta.dirname,
})

createConfig accepts:

• additionalIgnores?: string[] — extra glob patterns appended to the fleet-wide ignore defaults
• tsconfigRootDir?: string — root dir passed to typescript-eslint's projectService (defaults to process.cwd())
• tsProjects?: string[] — tsconfig paths used by eslint-import-resolver-typescript (defaults to ['./tsconfig.json'])
• internalRegex?: string — regex identifying "internal" workspace imports for import ordering (defaults to ^@cogs/)
• react?: boolean — enable the React + React Hooks + JSX a11y rule sets (defaults to true; set false for non-React packages)
• packageDirs?: string[] — directories to search when checking for extraneous dependencies

Need repo-specific tweaks? Spread and append:

import { createConfig } from '@cogs/eslint-config'

export default [
  ...createConfig({ tsconfigRootDir: import.meta.dirname }),
  {
    files: ['src/legacy/**/*.ts'],
    rules: { '@typescript-eslint/no-explicit-any': 'off' },
  },
]
