How can I implement authentication in a Vue.js app using Vuex?

To implement authentication in a Vue.js app using Vuex, you can follow these steps: 1. Set up Vuex store. 2. Create actions for login and logout. 3. Use mutations to update the state. 4. Store the authentication token in local storage.

Can you show me an example of the Vuex store setup?

Sure! Here's a basic example:

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

Vue.use(Vuex);

export default new Vuex.Store({
  state: {
    isAuthenticated: false,
    user: null,
  },
  mutations: {
    SET_AUTH(state, user) {
      state.isAuthenticated = true;
      state.user = user;
    },
    LOGOUT(state) {
      state.isAuthenticated = false;
      state.user = null;
    },
  },
  actions: {
    login({ commit }, user) {
      // Perform login logic, then commit mutation
      commit('SET_AUTH', user);
    },
    logout({ commit }) {
      commit('LOGOUT');
    },
  },
});

What about handling API calls for authentication?

You can use libraries like Axios to handle API calls. In your login action, you would make a POST request to your authentication endpoint and then commit the mutation based on the response.
