What are some tips for using Vue.js with TypeScript?

When using Vue.js with TypeScript, consider the following tips: 1. Use Vue's official TypeScript support. 2. Define your component props and data types clearly. 3. Leverage interfaces for better type safety. 4. Use the defineComponent function for better type inference.

Can you explain how to define props in a TypeScript component?

Sure! In a TypeScript component, you can define props using an interface. For example:

interface MyComponentProps {
  title: string;
  count: number;
}

export default defineComponent({
  props: {
    title: String,
    count: Number
  } as PropType<MyComponentProps>,
});

What about using Vuex with TypeScript?

When using Vuex with TypeScript, define your state, mutations, and actions with types. You can create a store with typed state like this:

interface State {
  count: number;
}

const store = createStore<State>({
  state: { count: 0 },
  mutations: {
    increment(state) {
      state.count++;
    }
  }
});
