Vue component to render content in a new window

vue-window-portal

Vue component to render content in a new window.

This works by creating the element in the main window and adding it to the newly created child window, which removes it from the main window. The original window handles all processing and logic of the now-moved component, so no script tags need to be copied over, just styles.

Known limitations

• Hot-reloading during development will cause the windows to close/open.
• Styles will not work if your page sets Content Security Policy style-src 'unsafe-inline'. Unfortunately this includes Github Pages.
  • You can get around this by adding an empty _window.html file to your deployed application.
• Styles cannot hot-reload because they are copied when the window is initially opened.
• Style/link tags not in document.head will not be copied to the new window (semi-intentional).

Demo

Live demo

Or run locally:

npm run serve

Example usage

See App.vue for a more detailed example.

<template>
  <div>
    Main content

    <vue-window-portal open>
      This content will be rendered in a new window
    </vue-window-portal>
  </div>
</template>

The window can be controlled via its open prop or via the openPortal() and closePortal() methods.

Use the .sync modifier to propagate changes back into your variable, or the @closed event if you only care when the window is closed.

Use the no-style option to avoid copying style tags into the new window.
