library15.0.3jsnpmunverified

Shared ESLint configs for Expo projects, providing a single dependency to set up ESLint with TypeScript, React, and Prettier. Currently at version 15.0.3, it follows Expo's release cadence and updates frequently to align with new ESLint rules and Expo SDK changes. Differentiators include automatic parser detection based on TypeScript usage, built-in support for React Native and React, and seamless integration with Expo's ecosystem. Requires ESLint >=8.10 and Prettier >=3. Notably, the default export provides a comprehensive base config, but developers often misuse the require path or fail to install peer dependencies.

Verified usage

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

default config

✓ module.exports = { extends: 'universe' }

✗ const config = require('eslint-config-universe')

Use the string 'universe' in ESLint config's extends array. Direct require is incorrect.

TypeScript config

✓ module.exports = { extends: 'universe/shared/typescript' }

✗ module.exports = { extends: 'universe/typescript' }

The TypeScript config is at 'universe/shared/typescript', not 'universe/typescript'.

Web config

✓ module.exports = { extends: 'universe/web' }

✗ module.exports = { extends: 'universe' } (without specifying web)

Use 'universe/web' for web projects; 'universe' includes React Native rules.

Sets up ESLint with Expo's recommended config. Requires installing peer deps and correct extends path.

// Install peer dependencies first // npm install --save-dev eslint prettier eslint-config-universe // .eslintrc.js module.exports = { extends: 'universe', // For TypeScript projects, use 'universe/shared/typescript' instead // For web projects, use 'universe/web' env: { node: true, browser: true, es2021: true, }, parserOptions: { ecmaVersion: 'latest', sourceType: 'module', }, };

Debug

Known issues

breakingSince version 12, the recommended config no longer automatically detects React Native; use 'universe' (includes RN) or 'universe/web' explicitly.

fix

Update your ESLint config: use 'universe' for RN or 'universe/web' for web projects.

affects: >=12.0

deprecatedThe 'universe/node' config is deprecated and will be removed in a future version.

fix

Use 'universe' or customize with 'universe/shared/typescript' as needed.

affects: >=14.0

gotchaMissing peer dependency 'prettier' causes runtime error: 'Cannot find module 'prettier''.

fix

Install prettier: npm install --save-dev prettier

affects: >=10.0

gotchaESLint 9 flat config is not supported; this config uses legacy .eslintrc format.

fix

Use ELLint 8.x or stick with legacy config until flat config support is added.

affects: >=9.0 (ESLint)
