{"library":"metro-babel-transformer","type":"library","category":null,"description":"The base Babel transformer for Metro, the JavaScript bundler for React Native. Current stable version is 0.84.3, with frequent releases (~monthly). This package provides the default Babel transformation pipeline used by Metro to transpile JavaScript/TypeScript files. It handles caching, config merging, and integration with Metro's build system. Key differentiators: it is the official transformer maintained by Meta, tightly coupled with Metro's caching and dependency resolution; supports custom Babel configs; and ships TypeScript types natively since v0.83.5. Alternatives like @react-native/babel-transformer exist but this is the core package.","language":"javascript","status":"active","version":"0.84.3","tags":["javascript","transformer","metro","typescript"],"install":[{"cmd":"npm install metro-babel-transformer","imports":["import { getTransformOptions } from 'metro-babel-transformer'","import MetroBabelTransformer from 'metro-babel-transformer'","import { customTransformOptions } from 'metro-babel-transformer'"]},{"cmd":"yarn add metro-babel-transformer","imports":[]},{"cmd":"pnpm add metro-babel-transformer","imports":[]}],"homepage":null,"github":"https://github.com/facebook/metro","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/metro-babel-transformer","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/metro-babel-transformer/compatibility"},"provenance":{"verified_status":null,"verified_at":null,"last_verified":"Wed Jun 17","next_check":"Fri Jul 24","install_tag":null}}
