@lapidist/eslint-config

Shared ESLint flat config for the Lapidist ecosystem.

Installation

pnpm add --save-dev @lapidist/eslint-config

Peer dependencies (install once per repo):

pnpm add --save-dev eslint @typescript-eslint/eslint-plugin @typescript-eslint/parser

Usage

createConfig — base config for ESM TypeScript packages

// eslint.config.js
import { createConfig } from '@lapidist/eslint-config';
import { dirname } from 'node:path';
import { fileURLToPath } from 'node:url';

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

createNodeConfig — Node.js packages that mix CJS and ESM

// eslint.config.js
import { createNodeConfig } from '@lapidist/eslint-config/node';
import { dirname } from 'node:path';
import { fileURLToPath } from 'node:url';

export default createNodeConfig({
  tsconfigRootDir: dirname(fileURLToPath(import.meta.url)),
  allowRequire: true, // permits require() in .cjs entry points
});

Options

createConfig(options)

| Option | Type | Default | Description | |--------|------|---------|-------------| | tsconfigRootDir | string | — | Absolute path to the package root. Pass dirname(fileURLToPath(import.meta.url)). | | tsconfigProject | string | './tsconfig.eslint.json' | Path to the tsconfig used by ESLint. | | ignores | string[] | [] | Additional glob patterns to ignore (merged with dist/** and node_modules/**). |

createNodeConfig(options)

Accepts all of the same options as createConfig, plus:

| Option | Type | Default | Description | |--------|------|---------|-------------| | allowRequire | boolean | false | Set to true to permit require() calls. |

What's included

Both configs apply:

• @typescript-eslint/strict-type-checked — strict type-aware rules
• @typescript-eslint/stylistic-type-checked — consistent TypeScript style
• @typescript-eslint/consistent-type-assertions: ['error', { assertionStyle: 'never' }] — no as assertions in source files

Test files (tests/**/*.ts) get relaxed overrides:

• consistent-type-assertions is turned off (assertions allowed in tests)
• no-floating-promises is turned off
