An issue arises when trying to utilize meta tags in Nuxtjs while incorporating TypeScript into the

When working with Nuxtjs, I encountered an issue regarding my permissionKeys on the page and checking user access in the middleware. Everything runs smoothly when my script language is set to js, but errors arise when set to lang="ts".

I tried to find a solution by using the vue-meta package, but unfortunately, I kept running into the same error.

<script lang="ts">
export default {
  meta: {
    authorization: ['Organization/List']
  },
  data() {
    return {
           text: this.$t('organization.title'),
    }
   }
}

As a result, I keep receiving this error message: "Property '$t' does not exist on type '{ meta: { authorization: string[]; }; data(): any; }'."

The issue seems to revolve around utilizing meta and global variables together, which remains unresolved for me at this time.

Answer №1

To implement this functionality, you can utilize the nuxt-property-decorator library. This library allows you to access the head property, which may not directly integrate with the vue-meta plugin. However, you can create a decorator within your class to manipulate the vue-meta package settings.

<script lang="ts">
import { Component, Vue } from 'nuxt-property-decorator';

@Component({
  layout: 'home',
  head() {
    return {
      title: 'Test Title',
      meta: [
        { hid: 'description', name: 'description', content: 'My custom description' }
      ]
    }
  }
})
export default class MainPage extends Vue {

}
</script>

Alternatively, you have the option to define your own decorator within the class itself.

If needed, you can also use the extendRoutes method, although it is not recommended but still functional :)

Create a permissions.js file with contents like below:

export const normalUser = [
  'route-name-invoices',
  'route-name-invoices-create'
];

In your nuxt.config.js, import your permissions file:

import { normalUser } from './permissions'

...
// Locate the router section or define it
router: {
  extendRoutes(routes) {
    return routes.map(route => {
      if (normalUser.includes(route.name)) {
        route.meta = { authorization: ['Organization/list'] };
      }
      return route;
    });
  }
}

When we use <type="ts">, we trigger TypeScript typechecking, which helps to identify errors in our code. Let's dissect the code to understand why the error is valid.

const obj = {
  meta: {
    authorization: ['Organization/List']
  },
  data() {
    return {
           text: this.$t('organization.title'),
    }
   }
};

export default obj;

In the data method, the reference to this actually points to the object obj, where we are trying to access the property $t. However, such a property does not exist in obj.
