{"library":"eslint-plugin-es-x","type":"library","category":null,"description":"ESLint plugin that disallows individual ECMAScript syntactic features from ES3 to upcoming proposals. Version 9.6.0 requires ESLint >=9.29.0 and Node.js ^20.19.0 || >=22.12.0. Actively maintained by eslint-community as a fork of the deprecated eslint-plugin-es. Provides 128+ granular rules to restrict specific syntax (e.g., BigInt, optional chaining, top-level await) with readable error messages. Ships TypeScript type declarations, flat config support, and predefined configs like 'no-new-in-es2023'. Unlike setting ecmaVersion in Espree, this plugin allows selective feature bans and gives clear feedback for restricted syntax.","language":"javascript","status":"active","version":"9.6.0","tags":["javascript","eslint","plugin","eslintplugin","typescript"],"last_verified":"Wed May 27","install":[{"cmd":"npm install eslint-plugin-es-x","imports":["import plugin from 'eslint-plugin-es-x'","import { configs } from 'eslint-plugin-es-x'","import { rules } from 'eslint-plugin-es-x'"]},{"cmd":"yarn add eslint-plugin-es-x","imports":[]},{"cmd":"pnpm add eslint-plugin-es-x","imports":[]}],"homepage":null,"github":"https://github.com/eslint-community/eslint-plugin-es-x","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/eslint-plugin-es-x","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/eslint-plugin-es-x/compatibility"}}
