{"library":"babel-plugin-polyfill-custom","type":"library","category":null,"description":"A Babel plugin that allows developers to freely customize polyfills, enabling the selection of any polyfill implementation (e.g., whatwg-fetch, unfetch, Zousan) instead of being limited to core-js or es-shims. Current stable version is 2.0.49, released on 2026-04-21, with weekly updates and frequent dependency bumps. Key differentiators: supports any polyfill, not just ECMAScript; uses browserslist to determine required polyfills; inserts polyfills via base64 data URIs for differential bundle serving. Alternative to @babel/preset-env's core-js-based polyfilling.","language":"javascript","status":"active","version":"2.0.49","tags":["javascript","babel","babel-plugin","polyfill"],"last_verified":"Wed May 27","install":[{"cmd":"npm install babel-plugin-polyfill-custom","imports":["import babelPluginPolyfillCustom from 'babel-plugin-polyfill-custom'","import { customPolyfills } from 'babel-plugin-polyfill-custom'","import type { PluginConfig } from 'babel-plugin-polyfill-custom'"]},{"cmd":"yarn add babel-plugin-polyfill-custom","imports":[]},{"cmd":"pnpm add babel-plugin-polyfill-custom","imports":[]}],"homepage":null,"github":"https://github.com/3846masa/babel-plugin-polyfill-custom","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/babel-plugin-polyfill-custom","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/babel-plugin-polyfill-custom/compatibility"}}
