What is the best way to retrieve class members using component properties?

I am looking to implement a mixin for setting the header and meta data in my project. I recently discovered vue-meta, which seems to work really well for this purpose. However, I am still getting acquainted with TypeScript and class-based components.

How can I access the class member pageTitle within the component properties of metaInfo()?

Here is some sample code:

import Vue from 'vue';
import { Component } from 'vue-property-decorator';

@Component({
  metaInfo() {
    return {
      title: pageTitle, // Here I want to retrieve the class member
    };
  },
})
export default class headerMixin extends Vue {
  pageTitle: string = 'Page Title'; // Defining the class member
}

Answer №1

If we take into account that the metaInfo function is receiving the component instance as its context, it can be implemented in the following way:

@Component({
  metaInfo(this: headerMixin) {
    return {
      title: this.pageTitle
    };
  },
})
export default class headerMixin extends Vue {
  pageTitle: string = 'Page Title';
}
