Nuxt

The @domscribe/nuxt package is a Nuxt 3+ module that handles relay startup, transform registration, and runtime initialization automatically.

Install

npm install -D @domscribe/nuxt

Basic Setup

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['@domscribe/nuxt'],
});

That is all you need for the default configuration. The module automatically:

Starts the relay daemon
Registers Vite and Webpack transform plugins
Injects relay and overlay globals into the app head
Installs a client-only runtime plugin that initializes the Vue adapter

Configuration

Configure Domscribe via the domscribe key in your Nuxt config:

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['@domscribe/nuxt'],
  domscribe: {
    debug: true,
    overlay: {
      initialMode: 'expanded',
    },
    relay: {
      port: 4400,
    },
  },
});

Configuration Options

The domscribe config key accepts a DomscribeNuxtOptions object:

Option	Type	Default	Description
`include`	`RegExp`	`/.(jsx	tsx
`exclude`	`RegExp`	`/node_modules	.test.
`debug`	`boolean`	`false`	Enable debug logging.
`relay`	`object`	`{}`	Relay server configuration (see below).
`overlay`	`boolean	object`	`true`

Relay Options

Option	Type	Default	Description
`relay.autoStart`	`boolean`	`true`	Auto-start the relay daemon if not running.
`relay.port`	`number`	`0` (dynamic)	Port for the relay server.
`relay.host`	`string`	`'127.0.0.1'`	Host for the relay server.
`relay.bodyLimit`	`number`	`10485760` (10 MB)	Max request body size in bytes.

Overlay Options

When overlay is an object:

Option	Type	Default	Description
`overlay.initialMode`	`'collapsed'	'expanded'`	`'collapsed'`
`overlay.debug`	`boolean`	`false`	Enable debug logging in the overlay.

Supported Versions

Nuxt 3+ with Vite (default) or Webpack builder

How It Works

The module orchestrates five steps during Nuxt setup:

Relay startup -- starts the relay daemon and discovers the actual host and port.
Head script injection -- injects window.__DOMSCRIBE_RELAY_PORT__, window.__DOMSCRIBE_RELAY_HOST__, and window.__DOMSCRIBE_OVERLAY_OPTIONS__ globals via app.head. This is necessary because Nuxt bypasses Vite's transformIndexHtml, so the Vite plugin's HTML injection does not fire.
Vite plugin registration -- registers the base @domscribe/transform Vite plugin for AST transformation on both server and client builds, with relay auto-start disabled (since the relay is already running).
Webpack fallback -- registers the webpack loader and plugin as a fallback for projects using the Webpack builder.
Runtime plugin -- installs a client-only Nuxt plugin that initializes the RuntimeManager with the VueAdapter and starts the overlay if configured.

The module only activates in development mode. In production builds, it is a no-op.
