@amj7/nativescript-vue-portal v1.1.3

PortalVue for NativeScript Vue 3

A Portal Component for NativeScript Vue 3, to render elements outside of a component, anywhere in your app.

Basic StackBlitz Example

Getting Started

1. Install the package:

   npm i @amj7/nativescript-vue-portal

2. Register the plugin in your main.ts (or equivalent):

   import { createApp } from 'vue'
   import Home from './components/Home.vue'
   import PortalVue from '@amj7/nativescript-vue-portal'
   
   const app = createApp(Home)
   PortalVue(app)
   app.start()

   This registers the necessary components and registers and App-level Provide for managing portal connections throughout your application.

3. Use the Portal and PortalTarget components in your App:

   <template>
     <Portal to="myDestination">
       <label text="Hello from the Portal!" />
     </Portal>
     <PortalTarget name="myDestination" />
   </template>

Special Considerations

RootLayout:

The RootLayout will break vue events if we teleport multiple items in-and-out of it. To fix this, the wrap-prop was added to render all items within a GridLayout.

<Frame>
  <Page actionBarHidden="true">
    <RootLayout>
      <GridLayout>
        <!-- content -->
      </GridLayout>

      <PortalTarget name="destination" wrap multiple/>
    </RootLayout>
  </Page>
</Frame>

To change the default wrap element, use the as-prop. (as="StackLayout")

Use without installing globally:

You can import the components directly. The first created instance of Portal or PortalTarget will try to register the required App-level Provide.

<script setup lang="ts">
import { PortalTarget } from '@amj7/nativescript-vue-portal'
</script>

<template>
  <PortalTarget name="destination" />
</template>

API

<Portal>

Props:

• to (String): The name of the PortalTarget where the content should be rendered.
• name (String | Symbol, default: Unique ID): A unique identifier for the portal. Defaults to a generated unique ID.
• disabled (Boolean, optional): If true, the portal will be disabled and the content will not be rendered in the target, but will render in it's original position.
• order (Number, optional): Specifies the rendering order of the portal content within the target, especially useful when using multiple. Lower numbers render first.
• slotProps (Object, optional): Props that are passed to the slot content of the portal, when it's rendered in it's original position.

<PortalTarget>

Props:

• name (String, required): The unique name that matches the to prop of a Portal.
• wrap (Boolean, optional, default: false): If true, wraps the rendered content in a layout element (specified by the as prop). Required when teleporting multiple items to a RootLayout to avoid event issues.
• as (String, optional, default: GridLayout): The NativeScript layout element to use as the wrapper when wrap is true.
• multiple (Boolean, optional, default: false): If true, allows multiple Portal components to render content to this PortalTarget.
• slotProps (Object, default: {}): Props that are passed to the slot content of the PortalTarget.

Emits:

• change (returns { hasContent: boolean, sources: Name[] }): Fires after items have been teleported in or out.
