@ryans-technology/eslint-config

Shared ESLint v9 flat-config helpers for Ryan's Technology monorepos.

These helpers are dependency-free and expect each project to pass in its locally installed ESLint modules/plugins. This avoids resolution issues with local file dependencies.

Usage

Backend (Azure Functions)

In packages/backend/eslint.config.mjs:

import eslint from '@eslint/js';
import eslintConfigPrettier from 'eslint-config-prettier';
import globals from 'globals';
import tseslint from 'typescript-eslint';
import backendConfig from '@ryans-technology/eslint-config/backend';

export default backendConfig({
  eslint,
  tseslint,
  eslintConfigPrettier,
  globals,
  tsconfigPath: './tsconfig.json',
  tsconfigRootDir: import.meta.dirname,
  extraIgnores: ['src/generated/**'],
});

Expo / React Native mobile app

In packages/mobile-app/eslint.config.mjs:

import eslint from '@eslint/js';
import globals from 'globals';
import importPlugin from 'eslint-plugin-import';
import reactHooksPlugin from 'eslint-plugin-react-hooks';
import reactNativePlugin from 'eslint-plugin-react-native';
import reactPlugin from 'eslint-plugin-react';
import tseslint from 'typescript-eslint';
import expoConfig from '@ryans-technology/eslint-config/expo';

export default expoConfig({
  eslint,
  tseslint,
  globals,
  reactPlugin,
  reactHooksPlugin,
  reactNativePlugin,
  importPlugin,
  tsconfigPath: './tsconfig.json',
  tsconfigRootDir: import.meta.dirname,
});

Notes

• Configs assume ESLint 9 and flat-config mode.
• Projects should clear any ESLINT_USE_FLAT_CONFIG=false shell export when running lint.
• backendConfig scopes typed TypeScript rules to *.ts/tsx files.
