I've included prop descriptions in my Vue.extend component.

Why don't I see any tips when entering keys in props?

How can I handle "props" in Vue extends? It seems like I'm passing a JSON object, but I want to pass an interface or something else?

I tried using an interface, but it didn't work at all.

Answer №1

Learn how to create interfaces using this method

types/index.ts

export interface AuthenticatedUser {
  firstName: string,
  lastName: string,
  twitterHandle?: string,
  location: Location
}

export interface Location {
  city: string,
  state: string
}

export interface Todo {
  title: string;
}

import { AuthenticatedUser, Todo } from '@/types' // importing AuthenticatedUser interface

export default Vue.extend({
    data: () => ({
        authenticatedUser: {} as AuthenticatedUser //declaring authenticatedUser as type AuthenticatedUser
    }),
    name: 'Inputx' as string,
    computed: {
      fullName(): string { // Computed Property returns a string
        return `${this.authenticatedUser.firstName} ${this.authenticatedUser.lastName}`
      },
    },
    props: {
      todos: {
        type: Todo[], // declaring todos as array of Type Todo (Todo is the interface)
        required: true,
        default: []
      }
    },
    mounted() {
      this.authenticatedUser = {
        firstName: `Dave`,
        lastName: `Berning`,
        twitterHandle: `@daveberning`,
        location: {
          city: `Cincinnati`,
          state: `OH`
        }
      }   
    },
});
