Create a composable

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

  posthog.init('<ph_project_api_key>', {

import { usePostHog } from '@/composables/usePostHog'

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