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

  1. Install the package

    Required

    Install the PostHog JavaScript library using your package manager:

    npm install posthog-js
    Vue version

    This guide is for Vue 3 and above. For Vue 2.x, see our Vue docs.

  2. Create a composable

    Required

    Create a new file src/composables/usePostHog.js:

    src/composables/usePostHog.js
    import posthog from 'posthog-js'
    

    export function usePostHog() {
      posthog.init('<ph_project_token>', {
        api_host: 'https://us.i.posthog.com',
        defaults: '2026-08-30'
      })
    

      return { posthog }
    }

  3. Import in your router

    Required

    In router/index.js, import the usePostHog composable and call it:

    router/index.js
    import { createRouter, createWebHistory } from 'vue-router'
    import HomeView from '../views/HomeView.vue'
    import { usePostHog } from '@/composables/usePostHog'
    

    const router = createRouter({
      history: createWebHistory(import.meta.env.BASE_URL),
      routes: [
        {
          path: '/',
          name: 'home',
          component: HomeView,
        },
        {
          path: '/about',
          name: 'about',
          component: () => import('../views/AboutView.vue'),
        },
      ],
    })
    

    const { posthog } = usePostHog()
    

    export default router

  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' })

  5. Next steps

    Recommended

    After installing PostHog and ensuring autocapture is enabled, head to your web analytics dashboard to see your data. And then check out our start here guide.

    PostHog tip: Web analytics works with anonymous events. This means if you are primarily using PostHog for web analytics, it can be significantly cheaper for you.
