You'll begin to notice as you build out your actions in Vuex, many of them will look quite similar. Creating a remove action looks almost the same as the add action except for using the axios.delete method then filtering out the deleted todo once the…

The default behavior of submitting an HTML form is to reload the page. You can use the Vue.js @submit.prevent syntax to avoid that behavior. Then wire together the @submitevent with an add Vuex action to handle an async post to an api. This lesson wa…

In a server-rendered application, if you attempt to load data before the page renders and the data fails to load, your application will not run unless you handle the error properly. This lesson walks you through the options of handling load errors so…

Streams give you the power to handle a "pending" state where you've made a request for data, but the data hasn't yet returned. You can leverage this pending stream to update your template as well which is often displayed as a "loader"…

You can conditionally add classes to Vue.js templates using v-bind:class. This will help display the status of a todo as you add a Vuex action to patch todos. This lesson walks you through setting up a toggle button that triggers a toggle action to p…

You add array of todos to the store simply by adding them to the state defined in your store/index.js file. You can access the array of todos using mapState then loop through and display them with v-for. This lesson walks you through the process of s…

Vuex 是一个专为 Vue.js 应用程序开发的状态管理模式.它采用集中式存储管理应用的所有组件的状态,并以相应的规则保证状态以一种可预测的方式发生变化. 基础知识这里不再重述,学习的话请自行到官网学习 https://vuex.vuejs.org/zh/ 文档最后有具体使用的实例,不想看基础的就直接下调页面~ 这里主要简单讲一讲Nuxt里怎么使用vuex, Nuxt.js 内置引用了 vuex 模块,所以不需要额外安装. Nuxt.js 会尝试找到应用根目录下的 store 目录,如果该目录…

Mutations perform synchronous modifications to the state, but when it comes to make an asynchronous operation, they become useless. Actions are a higher layer on the Vuex pattern, which allow to call mutations asynchronously or even call multiple mut…

You commit changes to state in Vuex using defined mutations. You can easily access these state mutations in your template using mapMutations. This lesson shows you have to wire together your Vue.js template with your Vuex store using mutations and ma…

什么是vuex? 官方的解释是:Vuex 是一个专为 Vue.js 应用程序开发的状态管理模式.它采用集中式存储管理应用的所有组件的状态,并以相应的规则保证状态以一种可预测的方式发生变化. 简单来说就是集中管理所有的状态. 为什么要用vuex? 对于父子组件之前的通信,父组件通过porps传递到子组件,子组件通过$emit发送事件都到父组件; 对于组件与组件之间的通信,可以new一个新的Vue实例,专门用来做event bus进行通信. 当多个组件之间共享一个状态时,event bus可能就变成…
