How can I use Vuex with TypeScript in my Vue.js project?

To use Vuex with TypeScript, you need to install Vuex and its TypeScript types. Then, you can define your store with proper types for state, getters, mutations, and actions.

Can you show me a simple example of a Vuex store in TypeScript?

Sure! Here's a basic example:

import Vue from 'vue';
import Vuex from 'vuex';

Vue.use(Vuex);

interface State {
  count: number;
}

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

export default store;

What are the benefits of using TypeScript with Vuex?

Are there any best practices for structuring a Vuex store with TypeScript?
