Tips for transferring data and events between named views within Vue Router

I have a layout structured like this:

.------------------------+----------------.
|  Current Tab Title     |      Controls  |
+------------------------+----------------+
|  Tab1 Tab2 [Tab3]                       |
+-----------------------------------------+
|  Main Content                           |
|                                         |
'-----------------------------------------'

The content in the "Controls" field should logically correspond to the current tab. However, due to rendering constraints, I cannot place it in the same Vue component as the tab itself. Additionally, the tab title should dynamically change based on the active tab.

To achieve this, I used the <router-link> components for Tab1, etc. and leveraged the $route.name field for the tab title. I explored using named views to display the controls.

However, I am struggling to figure out how to synchronize and interact with the state in the current tab from the controls within the Controls block.

For instance, I want to include a checkbox for Tab1 that affects the tab's behavior. This state should be managed within the Tab1 component rather than the Tab1Controls component. How can I pass the current checkbox value from the Tab1 instance to the Tab1Controls instance, and vice versa?

While this can be achieved using Vuex, I am exploring alternative solutions. The common advice is to lift state up the component hierarchy, but this approach seems challenging with the router. Moreover, storing the checkbox data in either the Tab1 or Tab1Controls components exclusively is preferable, as it is not relevant to other tabs.

After much experimentation, I have crafted a unique approach to solve this challenge. While it may not be perfect, it does get the job done and allows me to maintain state where it belongs.

To start, I developed a BaseTemplate component that houses the majority of the application's markup. Essentially, the App component now only contains the essentials, while the bulk of the content (including static elements) resides within BaseTemplate:

// BaseTemplate.vue
<template>
<div>
  <header>
    <slot name="title">{{ title }}</slot>
    <slot name="controls"/>
  </header>
  <nav>
    <router-link ...>
    <router-link ...>
  </nav>
  <main>
    <slot/>
  </main>
</div>
</template>

<script>
export default {
  props: ['title'],
};
</script>

// Tab1.vue
<template>
  <BaseTemplate title="First Tab">
    <template #controls>
      ...
    </template>

    main content goes here...
  </BaseTemplate>
</template>
...

With this setup, all properties specific to Tab1 are contained within its component, while shared elements are placed in a separate component.

However, there are some drawbacks to this approach. In a traditional configuration, common controls and navigations exist outside the route-view. But in this setup, they are actually different component instances for each tab, resulting in a flicker when switching between tabs. I am unsure if there is a way to address this issue.
