Usage

Use the crumbs property in route's meta to provide route label or/and parent route name as in example below:

Simple Example

new VueRouter({
  routes: [
    {
      path: '/',
      name: 'home',
      component: Home,
      meta: {
        crumbs: {
          label: 'Home',
          parent: '',
        },
      },
    },
    {
      path: '/posts',
      name: 'posts',
      component: Posts,
      meta: {
        crumbs: {
          label: 'Posts',
          parent: 'home',
        }
      }
    },
  ],
});

Component properties

The component vue2-crumbs has many options for customization

The HTML template of crumbs has the next structure

nav > ul > li > (a || span)

Label or i18n alias

If you have a multilingual application, then you can also specify i18n alias as crumb label. I18n is a higher priority property than the label

Example:

new VueRouter({
  routes: [
    {
      path: '/',
      name: 'home',
      component: Home,
      meta: {
        crumbs: {
          i18n: 'home',
          parent: '',
        },
      },
    },
  ],
});

If you use i18n then you need to use the library vue-i18n

Specifying a parameter from the url address

If in crumb you need to specify a parameter from the url address, then you can specify it directly in the label or in the translation of the i18n alias

Example:

new VueRouter({
  routes: [
    {
      path: '/posts/:post_id(\\d+)',
      name: 'post_view',
      component: PostView,
      meta: {
        crumbs: {
          label: 'Post #:post_id',
          // or
          // i18n: 'view_post', // where decryption of view_post is "Post #:post_id" 
          parent: 'posts',
        }
      }
    },
  ],
});

Define crumbs info in page component

You can define crumbs in page components. This would overwrite data in the router. In crumbs you can return both an object and an array of objects

Example:

export default {
  crumbs() {
    return [
      {
        label: 'Posts',
        name: 'posts',
      },
      {
        label: 'Post',
        name: 'post',
      },
    ];
  },
};

Dynamic crumbs

Sometimes in crumb needs dynamic information or information from the backend. In page components in crumbs you can define it

Example:

export default {
  crumbs() {
    return [
      {
        label: 'Post "' + this.oPost.name + '"',
        name: 'post',
      },
    ];
  },
};

Attention! If you define crumbs in a page component, then you need to call function this.changeCrumbs(); This is necessary in order for the computed values to be applied (for example, getting the post from the backend). You can call it both in created() and in the function to get information from the backend

Example:

export default {
  crumbs() {
    return [
      {
        label: 'Post "' + this.oPost.name + '"',
        name: 'post',
      },
    ];
  },
  created() {
    // some actions
    this.changeCrumbs();
  },
  // or
  methods: {
    getPost() {
      axios.get('/api/posts/1')
        .then((response) => {
          this.oPost = response.data;

          this.changeCrumbs();
        });
    },
  },
};
