VWebView

An embedded web view component for displaying web content. Maps to WKWebView on iOS and macOS, and android.webkit.WebView on Android.

Usage

<VWebView
  :source="{ uri: 'https://example.com' }"
  :style="{ flex: 1 }"
  @load="onLoad"
/>

Props

Prop	Type	Default	Description
`source`	`WebViewSource`	required	The content to display (URL or inline HTML)
`javaScriptEnabled`	`boolean`	`true`	Enable JavaScript execution in the web view
`style`	`StyleProp`	—	Layout + appearance styles

WebViewSource

interface WebViewSource {
  uri?: string   // URL to load
  html?: string  // Inline HTML string to render
}

Provide either uri or html, not both.

Events

Event	Payload	Description
`@load`	`{ url: string }`	Fired when the page finishes loading
`@error`	`{ message: string, url?: string }`	Fired when navigation fails; Android includes the failing URL
`@message`	`{ data: any }`	Fired when the web page posts a message through the platform's `vueNative` bridge

Example

Loading a URL

<script setup>
import { ref } from 'vue'

const loading = ref(true)

function onLoad(e) {
  loading.value = false
  console.log('Loaded:', e.url)
}

function onError(e) {
  loading.value = false
  console.log('Error:', e.message)
}
</script>

<template>
  <VView :style="styles.container">
    <VActivityIndicator v-if="loading" :style="styles.loader" />
    <VWebView
      :source="{ uri: 'https://vuejs.org' }"
      :style="styles.webview"
      @load="onLoad"
      @error="onError"
    />
  </VView>
</template>

<script>
import { createStyleSheet } from '@thelacanians/vue-native-runtime'

const styles = createStyleSheet({
  container: {
    flex: 1,
  },
  webview: {
    flex: 1,
  },
  loader: {
    position: 'absolute',
    top: 100,
    alignSelf: 'center',
  },
})
</script>

Loading inline HTML

<template>
  <VWebView
    :source="{ html: '<h1>Hello from Vue Native!</h1><p>This is inline HTML.</p>' }"
    :style="{ flex: 1 }"
  />
</template>

Receiving messages from web content

The web page can send messages to your Vue Native app using the platform's vueNative message handler.

On iOS and macOS, use WebKit's script message handler. The payload may be any value supported by WKScriptMessage:

window.webkit.messageHandlers.vueNative.postMessage({ type: 'ready', count: 42 })

On Android, use the injected window.vueNative interface. Android receives a string, so serialize structured data explicitly:

window.vueNative.postMessage(JSON.stringify({ type: 'ready', count: 42 }))

<template>
  <VWebView
    :source="{ uri: 'https://example.com' }"
    :style="{ flex: 1 }"
    @message="onMessage"
  />
</template>

<script setup>
function onMessage(e) {
  const data = typeof e.data === 'string' ? JSON.parse(e.data) : e.data
  console.log('Received from web:', data)
}
</script>

Notes

VWebView should typically be given flex: 1 or explicit dimensions, as it has no intrinsic content size.
The javaScriptEnabled prop is true by default and can be toggled at runtime. On iOS and macOS, changes use WKWebpagePreferences and apply to future navigations; they do not reload the current page.
On iOS and macOS, the @message event uses WKScriptMessageHandler with the channel name "vueNative".
Android blocks mixed HTTP content inside HTTPS pages by default.
