What is the best way to include documentation for custom components using jsDoc?

Within my Vuejs inline template components, we typically register the component in a javascript file and define its template in html.

An example of such a component is shown below:

Vue.component('compare-benefits', {
  data() {
     // By returning this object, the "this" keyword in methods should reference it
     return {
        ...state,
        isLoading: false,
     }
  },
  methods: {
    getData() {
       // How can I make sure that the "this" keyword here points to the object returned in the data method above?
       this.isLoading = true;
    }
  }
})

If you're not familiar with Vue, essentially what's happening is that Vue will automatically bind the this keyword in your methods to the object returned from the data() method.

I'm wondering how I can use jsDoc to specify that the this keyword within this context is referring to that particular object?

EDIT: The main reason for incorporating jsDoc isn't just for documentation purposes but also to enable intellisense and type checking in vscode using @ts-check

Answer №1

The this keyword in the realm of Vue framework refers to an object of type Vue. To identify it, one can easily debug code within the getData method or any other method. It's worth noting that the Vue data comprises properties of this. Below is a screenshot as an example from a current project I am working on:

After utilizing jsDoc, your code will resemble something like this:

Vue.component('compare-benefits', {
    data() {
        return {
            ...state,
            isLoading: false,
        }
    },
    methods: {
        /** @this Vue */
        getData() {
            this.isLoading = true;
        }
    }
})

Answer №2

While I am not familiar with Vue.js, I have a good understanding of JSDoc that may be useful to you. When documenting the 'this' keyword, it can be done as shown below:

/**
 * @this Vue
 */

In order to properly document 'Vue', refer to the Vue.js documentation where it should be declared in JSDoc. For further examples on creating classes, enums, functions, and more, along with their usage in JSDoc, you can check out this file.
