How do I manage state in a Vue application?

In Vue, you can manage state using Vuex, which is a state management library specifically designed for Vue applications.

What are the main concepts of Vuex?

The main concepts of Vuex include state, getters, mutations, actions, and modules. State holds the data, getters retrieve it, mutations modify it, actions handle asynchronous operations, and modules allow for organizing the store.

Can you give me an example of using Vuex in a component?

Sure! In a Vue component, you can use mapState to access state and mapMutations to commit mutations. Here's a simple example:

import { mapState, mapMutations } from 'vuex';

export default {
  computed: {
    ...mapState(['count'])
  },
  methods: {
    ...mapMutations(['increment'])
  }
};

What are some common pitfalls when using Vuex?

Common pitfalls include overusing Vuex for local state, not structuring the store properly, and forgetting to use mutations for state changes.
