Missing `pkg.exports` in package.json

Context

posthog-js can't be used in ESM/SSR Node projects (Remix/Vite): package.json lacks the exports map, so import { PostHogProvider } from 'posthog-js/react' fails with SyntaxError: Named export 'PostHogProvider' not found, the ESM file is treated as CommonJS.

Verified resolution

Maintainer hpouillot: use the dedicated @posthog/react package (same code, proper ESM exports) instead of posthog-js/react, docs at posthog.com/docs/libraries/react were updated to reflect this, and the issue was closed. Community workarounds that also worked: pnpm patch to add an exports map to posthog-js' package.json, or ssr: { noExternal: ['posthog-js'] } in vite.config.ts.
