Setting Metadata Dynamically in Vue Router

Setting Metadata Dynamically in Vue Router

Currently, I have a Single Page Application (SPA) built with Vue and Vue Router. The setup mimics an iOS app where the title in the navigation bar changes as you navigate deeper into the views. Right now, the titles are hardcoded in the routes.js file, but I'd like to make them dynamic. I tried updating the route meta within my view, but it renders after the view is shown, so I need it to happen before the route change occurs. Here's how it's currently set up:

routes.js

// Example of a route
{   
    path: '/team/:username', 
    component: require('./views/team-single'),  
    name: 'profile', 
    meta:{ requiresAuth: true, title: 'Team Member', tabbar: false } 
}

navbar.vue

// If the route has a title, show it; otherwise show the logo
 <div class="navbar-item">

     <transition name="fadeup">
         <h1 v-if="$route.meta.title" class="navbar-title">{{ $route.meta.title }}</h1>
         <img src="/img/hopbak-green.svg" class="navbar-logo"  alt="hopbak" v-else>
     </transition>

 </div>

Ideally, it would be great to pass the :username parameter into the title in the route.js, but that doesn't seem possible. I attempted to add something like this in the view, but as mentioned earlier, it gets called too late:

team-member.vue

mounted(){
   this.$route.meta.title = this.user.username
}

This code does change the title, however, it happens after the navbar has already loaded.

Answer №1

I encountered a similar issue involving dynamic URL parameters in metadata, but I was able to resolve it by using the meta attribute of this.$route as a function. To begin, set up the meta attribute like this:

// Define a route
 {   
      path: '/team/:username', 
      component: require('./views/team-single'),  
      name: 'profile', 
      meta: (route) => ({ requiresAuth: true, title: 'Team Member' + route.params.username, tabbar: false }) 
  }

Next, you can utilize it in your template by following this structure:

// Display the title instead of the logo if it exists in the route's meta data
 <div class="navbar-item">

     <transition name="fadeup">
         <h1 v-if="$route.meta != null" class="navbar-title">{{ $route.meta($route).title }}</h1>
         <img src="/img/hopbak-green.svg" class="navbar-logo"  alt="hopbak" v-else>
     </transition>

 </div>

Once I updated the meta information, I triggered a router reload using the following method:

this.$route.meta.title = this.user.username

// Introduce a temporary query parameter.
this.$router.replace({query: {temp: Date.now()}})
// Eliminate the temporary query parameter.
this.$router.replace({query: {temp: undefined}})

Various solutions for forcing a router reload can be found in this GitHub issue. The approach mentioned above is just one of many.

To achieve a similar outcome, you can utilize the props feature.

{
  path: '/team/:username',
  name: 'profile',
  component: require('./views/team-single'),
  props: (route) => ({ title: route.params.username })
}

In your component file:

props: ['title'],
...
mounted () {
  console.log('title: ' + this.title)
}
...

For more details, refer to the official documentation: https://router.vuejs.org/en/essentials/passing-props.html

When the meta object is set as a function, it prevents the combination of its values with all matched routes. According to information from the documentation:

...Vue Router also offers a $route.meta that represents a non-recursive merge of all meta fields from parent to child.

The most effective solution is to define the value of the specific meta property as a function. For example, using Pinia:

meta: {
  title: () => useProjectsStore()?.currentItem?.title || 'Project dashboard',
}

Before utilizing the value, ensure to check its type:

  {{
    typeof item.meta?.title === 'function' 
    ? item.meta.title()
    : item.meta?.title
  }}

// example of different ways to use router.push in Vue.js

// using literal string path
router.push('/users/eduardo')

// passing an object with path
router.push({ path: '/users/eduardo' })

// utilizing a named route with params for dynamic URLs
router.push({ name: 'user', params: { username: 'eduardo' } })

// including query parameters for additional data in the URL
router.push({ path: '/register', query: { plan: 'private' } })

// adding a hash value to the URL
router.push({ path: '/about', hash: '#team' })


const userId = '123'
router.push({ name: 'user', params: { userId } }) // -> /user/123
router.push({ path: `/user/${userId}` }) // -> /user/123
// This will NOT work as expected
