Vue Surveys installation

Install the package

Required

Install the PostHog JavaScript library using your package manager:

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

Vue version

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

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: '2026-01-30'
  })

  return { posthog }
}

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

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' })
