Remix Product Analytics installation

Install the package

Required

Remix version

This guide is for Remix v2. For Remix v3, see our React Router v7 docs.

Install the PostHog JavaScript library using your package manager:

npm install posthog-js
yarn add posthog-js
pnpm add posthog-js

Configure Vite

Required

Add posthog-js and @posthog/react to ssr.noExternal in your vite.config.ts so they get bundled for SSR:

vite.config.ts
// ... imports and rest of config

export default defineConfig({
  plugins: [
    remix({
      future: {
        v3_fetcherPersist: true,
        v3_relativeSplatPath: true,
        v3_throwAbortReason: true,
        v3_singleFetch: true,
        v3_lazyRouteDiscovery: true,
      },
    }),
    tsconfigPaths(),
  ],
  ssr: {
    noExternal: ["posthog-js", "@posthog/react"],
  },
});

Create a provider

Required

Create a provider.tsx file in the app folder. Set up the PostHog provider to initialize after hydration:

app/provider.tsx
import { useEffect, useState } from "react";
import posthog from "posthog-js";
import { PostHogProvider } from "@posthog/react";

export function PHProvider({ children }: { children: React.ReactNode }) {
  const [hydrated, setHydrated] = useState(false);

  useEffect(() => {
    posthog.init("<ph_project_token>", {
      api_host: "https://us.i.posthog.com",
      defaults: "2026-01-30"
    });

    setHydrated(true);
  }, []);

  if (!hydrated) return <>{children}</>;
  return <PostHogProvider client={posthog}>{children}</PostHogProvider>;
}

Wrap your app

Required

Import the PHProvider component in your app/root.tsx file and use it to wrap your app:

app/root.tsx
// ... imports
import { PHProvider } from "./provider";

// ... links, meta, etc.

export function Layout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="en">
      <head>
        <meta charSet="utf-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1" />
        <Meta />
        <Links />
      </head>
      <body>
        <PHProvider>
          {children}
          <ScrollRestoration />
          <Scripts />
        </PHProvider>
      </body>
    </html>
  );
}

export default function App() {
  return <Outlet />;
}

Send events

Click around and view a couple pages to generate some events. PostHog automatically captures pageviews, clicks, and other interactions for you.

If you'd like, you can also manually capture custom events:

JavaScript
posthog.capture('my_custom_event', { property: 'value' })
