{"library":"babel-preset-umi","type":"library","category":null,"description":"A Babel preset used internally by the Umi.js framework to transpile modern JavaScript/TypeScript and JSX for browser or Node targets. The latest stable version is 1.8.4, though it is tightly coupled with Umi major versions (e.g., Umi 4). It supports browserslist targets, polyfills via core-js, and optional transforms like Preact. Unlike generic presets (e.g., @babel/preset-env), this preset is designed for Umi's build pipeline and may include framework-specific optimizations. Release cadence follows Umi's release cycle. It is recommended to use this preset only within Umi projects.","language":"javascript","status":"active","version":"1.8.4","tags":["javascript"],"last_verified":"Wed May 27","install":[{"cmd":"npm install babel-preset-umi","imports":["module.exports = { presets: ['umi'] }","module.exports = { presets: [['umi', { targets: { node: '6' } }]] }","// In .babelrc: { \"presets\": [\"umi\"] }"]},{"cmd":"yarn add babel-preset-umi","imports":[]},{"cmd":"pnpm add babel-preset-umi","imports":[]}],"homepage":"https://umijs.org","github":"https://github.com/umijs/umi","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/babel-preset-umi","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-preset-umi/compatibility"}}
