What are the best practices for using Vue with TypeScript?

When using Vue with TypeScript, it's important to define your component props and data types clearly. Use interfaces for props and define the types of your data properties.

Can you give me an example of how to define props in a Vue component?

Sure! You can define props in a Vue component like this:

import { defineComponent } from 'vue';

export default defineComponent({
  props: {
    title: {
      type: String,
      required: true
    },
    count: {
      type: Number,
      default: 0
    }
  }
});

What about using Vuex with TypeScript?

For Vuex, you can define your state, mutations, and actions with TypeScript types to ensure type safety. Use interfaces for your state and payloads.

Are there any tools that can help with TypeScript in Vue?

Yes! Tools like Vetur and Volar provide excellent TypeScript support in Vue files, offering features like type checking and IntelliSense.
