library2.0.4jsnpmunverified

ESLint plugin for create-universal-package (cup), providing a custom no-undef rule that allows environment-specific globals (e.g., window, process) only when guarded by __BROWSER__ or __NODE__ checks. Current stable version 2.0.4, last release likely in 2019. Designed for universal code that runs in both browser and Node.js, enforcing that environment-sensitive globals are used only within appropriate conditional blocks. Requires ESLint 5.x or 6.x. Not actively maintained.

Verified usage

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

rules
✓ import { rules } from 'eslint-plugin-cup'
✗ const rules = require('eslint-plugin-cup').rules
ESM import works; the package also provides a CommonJS entry via module.exports.
configs
✓ import { configs } from 'eslint-plugin-cup'
✗ const configs = require('eslint-plugin-cup').configs
Exported for programmatic use, but typically not needed.

Configures ESLint to use the cup/no-undef rule instead of the default no-undef.

// .eslintrc.js module.exports = { plugins: ['cup'], rules: { 'cup/no-undef': 'error' } };
