To learn more possibilities tags in HEAD

Example with files .vue

<template>
  <!-- Code here -->
</template>

export default {
  data: function () {
    return {
      title: 'My Title'
    }
  },
  // Usage with context the component
  head: {
    // To use "this" in the component, it is necessary to return the object through a function
    title: function () {
      return {
        inner: this.title
      }
    },
    meta: [
      { name: 'description', content: 'My description', id: 'desc' }
    ]
  }
    ...
  }
}

<style scoped>
  /* Code here */
</style>

Custom title

You can customize the page title with tab and complement, just add the properties separator and complement object in title Separator by default uses the pipe character | and complement by default uses the title of the html document

head: {
  title: {
    inner: 'My title',
    separator: '-',
    complement: 'My Complement'
  },
  //omited
}

If not please complement defines an empty value

Default custom title

If you'd like to set default custom title options on every component you can pass options to VueHead when you're registering it for Vue, just like in example below.

const VueHead = require('vue-head')

Vue.use(VueHead, {
  separator: '-',
  complement: 'My Complement'
})

Using `this`

For using values with this, it is necessary to return the object through a function

data: {
  myData: 'My description'
},
// omited
meta: function () {
  return [
    { name: 'description', content: this.myData }
  ]
}

The whole head option can be a function.

Undo elements

All created tags will be removed as you leave the component, but you may want it to be not broken and remain in the DOM.
So you should set undo: false

style: [
  { type: 'text/css', inner: 'body { background-color: #000; color: #fff}', undo: false }
]

Replace content the elements

There are some tags that are unique and that only need to update the content, such as meta tags name="description" or rel="canonical".
Therefore, it is necessary to define a id, so that the element is found and is made the update correctly, avoiding duplicates tags.

meta: [
  { name: 'description', content: 'A description of the page', id: 'desc' }
]

Event emitted

Vue 1.*

At some point you may want to do something after the DOM is complete with the changes, to this the vue-head emits through the key okHead.
With this, you can hear through the events option of your instance component.

// omited
events: {
  okHead: function () {
    // Do something
  }
},

Vue 2.*

created: function () {
  this.$on('okHead', function () {
    // Do Something
  });
}

Update elements with asynchronous data or after page loaded

Keep the data tags updated through an update of the elements that have changed data, which are the reactive data of your component. It is not automatic if you want to upgrade, simply issue the event updateHead soon after changing your data.

For example:

// omited
methods: {
  getAsyncData: function () {
    var self = this
    window.setTimeout(function () {
      self.title = 'My async title'
      self.$emit('updateHead')
    }, 3000)
  }
},

Note: I recommend you use the vueRouter to request the data from the tags and build the header tags with synchronous data, updating real-time meta tags only have to use the business rules of your application.

Keep alive

Supported only in Vue next >2.0.*, Because it uses the new hooks activated and deactivated.
Obs: In version <1.0. * Using making prompt to maintain the element in the document.
