Set Data Type in Vue Data Object with Typescript

In Vue.js with TypeScript, you can define data types for properties in the data object using TypeScript syntax. To do this, you can create an interface defining the structure of your component’s data and then use that interface for typing your component’s data function.

Here’s an example of how you can define types for properties in the data object using TypeScript in a Vue component:

// Define an interface for the component's data
interface MyComponentData {
 name: string;
 age: number;
 email: string;
 isActive: boolean;
 hobbies: string[];
 userDetails: {
   address: string;
   city: string;
   // ... other properties in userDetails object
 };
}
export default {
 data(): MyComponentData {
   return {
     name: 'John',
     age: 30,
     email: '[email protected]',
     isActive: true,
     hobbies: ['Reading', 'Running', 'Gaming'],
     userDetails: {
       address: '123 Main St',
       city: 'Anytown'
       // ... initialize other properties in userDetails object
     },
     // ... initialize other properties here
   };
 },
 // ... other component options
}
