single-spa-react

single-spa-react is a utility library designed to simplify the integration of React applications and components into a single-spa microfrontend architecture. It provides helper functions that adapt React's rendering and lifecycle methods (bootstrap, mount, unmount) to single-spa's expectations. The current stable version is 6.0.2, with ongoing active development including patch releases and a v7.0.0-beta.0 in progress. Key differentiators include robust support for React 18's `createRoot` API, explicit compatibility options for older React versions, built-in error boundary mechanisms, and a dedicated `<Parcel>` component for managing framework-agnostic micro-frontends within a React application. It focuses on ensuring React applications adhere to single-spa's lifecycle contracts and work seamlessly within a polyglot microfrontend environment.
