Nuxt Config Setup

Add this to your nuxt.config.ts to load Segment globally. Alternatively you can use the useScriptSegment composable for more control.

export default defineNuxtConfig({
  scripts: {
    registry: {
      segment: {
        writeKey: 'YOUR_WRITE_KEY',
        trigger: 'onNuxtReady',
      }
    }
  }
})

This config automatically enables first-party mode (bundle). See below to customise.

useScriptSegment()

The useScriptSegment composable lets you have fine-grain control over when and how Segment is loaded on your site.

const { proxy } = useScriptSegment()

proxy.track('conversion', { value: 1, currency: 'USD' })

Please follow the Registry Scripts guide to learn more about advanced usage.

First-Party Mode: Privacy Focused Proxy

No extra config needed. The script is bundled and served from your domain instead of a third-party CDN, eliminating an extra DNS lookup and improving load times. Learn more.

export default defineNuxtConfig({
  scripts: {
    // ✅ First-party mode: bundled
    registry: {
      segment: {
        writeKey: 'YOUR_WRITE_KEY',
        trigger: 'onNuxtReady',
      },
    },
  },
})

Example

Using Segment in a component.

<script setup lang="ts">
const { proxy } = useScriptSegment()

// noop in development, ssr
// just works in production, client
function handleAction() {
  proxy.track('conversion', { value: 1, currency: 'USD' })
}
</script>

<template>
  <div>
    <button @click="handleAction">
      Send Event
    </button>
  </div>
</template>
