eslint-plugin-no-use-extend-native

0.7.2 verified Sat Apr 25 auth: no javascript

ESLint plugin (v0.7.2) to prevent use of extended native objects like arrays, strings, and prototypes. Works alongside ESLint's no-extend-native rule to ensure code doesn't depend on prototype modifications from libraries such as 'colors'. Requires Node >=18.18.0 and ESLint ^9.3.0 (flat config only). Actively maintained with periodic updates.

Common errors

error Error: Failed to load plugin 'no-use-extend-native' declared in 'plugins': Cannot find module 'eslint-plugin-no-use-extend-native' ↓

cause Plugin not installed or wrong import path.

fix

Run 'npm install --save-dev eslint-plugin-no-use-extend-native' and ensure package.json includes it.

error ESLint couldn't determine the plugin name from ESLint configuration: 'no-use-extend-native' ↓

cause Using deprecated .eslintrc config format with flat config plugin.

fix

Switch to eslint.config.js and import the plugin as shown in Quickstart.

error Parsing error: The keyword 'import' is reserved ↓

cause Using require() instead of import in ESM-only context.

fix

Use ESM import syntax: import eslintPluginNoUseExtendNative from 'eslint-plugin-no-use-extend-native'

Warnings

breaking v0.5.0 dropped CommonJS support; flat config only. ↓

fix Use ESM imports and eslint.config.js file; remove .eslintrc usage.

breaking v0.4.0 changed rule name from 'no-use-extend-native/no-use-extend-native' to same but broke some custom configurations. ↓

fix Update rule key if you had custom rule configuration.

gotcha Plugin does not detect extensions made after the check – only static analysis. ↓

fix Use dynamic import or manual review for runtime prototype modifications.

deprecated v0.3.x was last to support Node <10 and ESLint <6. ↓

fix Upgrade to latest version and use ESLint flat config.
