In Vue.js how to use multiple router-views one of which is inside another component?

Question

I have a Vue.js single page application where there is a main navbar that uses <router-view/> to render different pages.

Something like this:

<main-header/> <!-- navigation links -->
<transition name="slide-fade" mode="out-in">
  <router-view/> <!-- different pages -->
</transition>

In one of those pages I have a sidebar that has more navigation links (that are using <router-link/> just like the main navbar.

Something like this:

<sidebar/> <!-- navigation links -->
<div class="content">
  <transition name="slide-fade" mode="out-in">
    <router-view/> <!-- content beside the sidebar -->
  </transition>
</div>

When I click on the sidebar navigation links I want the content beside the sidebar to change as well as the url to change. However, I lose the sidebar, and just get the component that is to be rendered in the content section.

How do I achieve the desired result? How do I use multiple <router-view/>s one of which is inside another component, like the example above?

Answer 1

You need to use named views. Provide the name attribute to the view.

<router-view class="view one"></router-view>
<router-view class="view two" name="a"></router-view>

And configure them like

const router = new VueRouter({
  routes: [
    {
      path: '/',
      components: {
        default: Foo,
        a: Bar
      }
    }
  ]
})

Please refer to the official docs.

@adoug answer helped me.

But in my case, I had named both router-view:

I did this to fix it:

<router-view name='a'/>
<router-view name='b'/>

You have , somewhere inside you FatherComponent.vue mounted in a you have a second

I did this, to fix it:

const router = new VueRouter({
    routes: [
        { path: '/your-sidebar-url',
            components: {
                a: FatherComponent //you sidebar main component in 'a' name of routed-view
            },
            children: [
                {
                    // A will be rendered in the second <router-view>
                    // when /your-sidebar-url/a is matched
                    path: '/child-path/a',
                    components: {
                        b: ChildComponentA //note that 'b' is the name of child router view
                    }
                },
                {
                    // B will be rendered in the second <router-view>
                    // when /your-sidebar-url/b is matched
                    path: '/child-path/b',
                    components: {
                        b: ChildComponentB //note that 'b' is the name of child router view
                    }
                }
            ]
        }
    ]
})

Named Route views

const Foo = { template: '<div>foo</div>' }
const Bar = { template: '<div>bar</div>' }
const Baz = { template: '<div>baz</div>' }

const router = new VueRouter({
  mode: 'history',
  routes: [
    { path: '/',
      // a single route can define multiple named components
      // which will be rendered into <router-view>s with corresponding names.
      components: {
        default: Foo,
        a: Bar,
        b: Baz
      }
    },
    {
      path: '/other',
      components: {
        default: Baz,
        a: Bar,
        b: Foo
      }
    }
  ]
})

new Vue({
    router,
  el: '#app'
})

<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>

<div id="app">
  <h1>Named Views</h1>
  <ul>
    <li>
      <router-link to="/">/</router-link>
    </li>
    <li>
      <router-link to="/other">/other</router-link>
    </li>
  </ul>
  <router-view class="view one"></router-view>
  <router-view class="view two" name="a"></router-view>
  <router-view class="view three" name="b"></router-view>
</div>
