Install with the wizard

Run this command in your project directory to add PostHog to your React Router project. The wizard detects your framework, installs the SDK, and sets up your first events.

Or set it up manually by following the rest of this guide.

  1. Install the package

    Required

    Install the PostHog JavaScript library and React SDK using your package manager:

    npm install --save posthog-js @posthog/react

  2. Configure Vite

    Required

    Add posthog-js and @posthog/react to ssr.noExternal in your vite.config.ts to avoid SSR errors:

    vite.config.ts
    // ... imports
    

    export default defineConfig({
      plugins: [tailwindcss(), reactRouter(), tsconfigPaths()],
      ssr: {
        noExternal: ['posthog-js', '@posthog/react'],
      },
    });

  3. Add the PostHogProvider

    Required

    Initialize PostHog and wrap your app with the PostHogProvider in your app/entry.client.tsx file:

    app/entry.client.tsx
    import { startTransition, StrictMode } from "react";
    import { hydrateRoot } from "react-dom/client";
    import { HydratedRouter } from "react-router/dom";
    import posthog from "posthog-js";
    import { PostHogProvider } from "@posthog/react";
    

    posthog.init("<ph_project_token>", {
      api_host: "https://us.i.posthog.com",
      defaults: "2026-08-30",
    });
    

    startTransition(() => {
      hydrateRoot(
        document,
        <PostHogProvider client={posthog}>
          <StrictMode>
            <HydratedRouter />
          </StrictMode>
        </PostHogProvider>,
      );
    });

  4. 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' })
