  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
