Implementing mixin functions in vue.router routes with Vue.js

Implementing mixin functions in vue.router routes with Vue.js

Is there a way to dynamically change the title of the window based on each route? I have included a meta: { title: ... } object in each child object within the routes: []. Here is an example:

routes: [
{
  path: 'profile/:id',
  name: 'Profile',
  component: Profile,
  meta: {
    title: function (to, cb) {
      const profileId = parseInt(to.params.id);
      // ... do stuff ...
    }
  }
}
]

I am trying to call this title function using an afterEach hook:

router.afterEach((to) => {
    document.title = 'My Site';
    if (to.meta && to.meta.title) {
        to.meta.title(router.app, to, (result) => { document.title += ' | ' + result; });
    }
});

Within the ... do stuff ... section, I need to use a method from my mixin GetAndStore.js called loadProfile(profileId). Even after adding GetAndStore to the router's mixins and loading it globally, I am unable to access loadProfile as it shows as undefined (this.loadProfile). Despite trying various configurations for over an hour, I have been unsuccessful in accessing methods from the GetAndStore mixin within this setup.

Any suggestions on what might be missing or how I can restructure to access mixin methods within

routes->element->meta->title

?

The main concern here is...

Mixins offer a versatile method to share reusable functionalities for Vue components

It's important to note that Vue-router is not considered a component, and the component loaded for the route may not be directly accessible.

One suggestion would be to transform loadProfile into a named export from your GetAndStore mixin. Assuming your mixin is exported as shown below:

import axios from 'axios' // just an example

export default {
  methods: {
    loadProfile (profileId) {
      return axios.get(...)
    }
  }
}

You can separate the function from the default export and assign it a name like this:

export function loadProfile (profileId) {
  return axios.get(...)
}

export default {
  methods: {
    loadProfile
  }
}

Then, in your route definitions, you can import only the loadProfile function:

import { loadProfile } from 'GetAndStore'

Alternatively, you could import your mixin as is and utilize it by calling:

import GetAndStore from 'GetAndStore'

// snip

GetAndStore.methods.loadProfile(to.params.id).then(...)

One approach could be implementing the logic within the beforeRouteEnter method inside the Profile component. This way, you can extract the meta title and dynamically set the page title. Additionally, this method provides access to mixin methods for further functionality:

beforeRouteEnter (to, from, next) {
  if (to.meta && to.meta.title) {
    to.meta.title(router.app, to, (result) => { document.title += ' | ' + result; });
  }
},
