Nuxt and Vue

The CLI prints the snippet for Nuxt instead of editing files (and exits with code 1, asking you to place it). Add it in nuxt.config; with a pinned version, copy integrity and crossorigin: 'anonymous' into the entry too:

export default defineNuxtConfig({
  app: {
    head: {
      script: [{ src: 'https://collect.plaintrace.dev/t.js', async: true, 'data-site': '<site id>' }],
    },
  },
})

For a Vite-built Vue app, the CLI adds the script to index.html. Router navigations are recorded automatically in both.
