{"library":"polyfills-db","type":"library","category":null,"description":"A database of browser polyfill features, version 3.0.0, released as needed. Provides structured metadata about which browsers support each feature and which modules/files implement it. Supports runtime JS polyfills, recast-based JS transpilation, and postcss-based CSS transpilation. Key differentiator: centralized polyfill data for multiple transpilation targets, manually maintained with community contributions. Release cadence: irregular, stable.","language":"javascript","status":"active","version":"3.0.0","tags":["javascript","database","db","polyfills","features","detects"],"install":[{"cmd":"npm install polyfills-db","imports":["import polyfillsDB from 'polyfills-db'","import { data } from 'polyfills-db'","import { features } from 'polyfills-db'","import { browsers } from 'polyfills-db'"]},{"cmd":"yarn add polyfills-db","imports":[]},{"cmd":"pnpm add polyfills-db","imports":[]}],"homepage":null,"github":"https://github.com/polyfills/db","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/polyfills-db","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/polyfills-db/compatibility"},"provenance":{"verified_status":null,"verified_at":null,"last_verified":"Wed Jun 17","next_check":"Fri Jul 24","install_tag":null}}
