{"library":"react-helmet-async","title":"Thread-safe Async React Helmet","description":"react-helmet-async is a robust solution for managing document head tags (title, meta, link, etc.) in React applications, designed to be thread-safe for server-side rendering (SSR). It addresses the limitations of the original `react-helmet` by encapsulating state on a per-request basis through a ``, crucial for asynchronous SSR environments. The current stable version is 3.0.0, which introduces significant adaptations for React 19+, leveraging React's native metadata hoisting capabilities while maintaining backward compatibility for React 16-18. It differentiates itself by providing a consistent API across React versions, handling `htmlAttributes` and `bodyAttributes` consistently, and offering a context for SSR data extraction, although this context behaves differently in React 19. Releases appear to follow a non-strict cadence, driven by major React version updates and feature enhancements.","language":"javascript","status":"active","last_verified":"Sun Apr 19","install":{"commands":["npm install react-helmet-async"],"cli":null},"imports":["import { Helmet } from 'react-helmet-async';","import { HelmetProvider } from 'react-helmet-async';","const { helmet } = helmetContext;"],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"import React from 'react';\nimport { createRoot } from 'react-dom/client';\nimport { Helmet, HelmetProvider } from 'react-helmet-async';\n\nconst App = () => (\n
