Vue

Vue is a progressive JavaScript framework for building user interfaces. It combines declarative rendering, component-based architecture, and reactive data binding to simplify the development of complex web applications. Vue's gentle learning curve and intuitive API make it accessible to both beginners and experienced developers. It provides a flexible and scalable structure for creating reusable UI components and managing application state. Vue's reactivity system ensures that the UI updates automatically when the underlying data changes.

Module 1: Getting Started with Vue.js

Introduction to Vue.js

Vue.js is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable.

new Vue({
  el: '#app',
  data: {
    message: 'Hello Vue!'
  }
})

Vue Directives

Vue.js uses a DOM-based templating system. Directives are special attributes with the v- prefix that you can use to bind data to the DOM, handle events, etc.

<div id="app">
  {{ message }}
</div>

new Vue({
  el: '#app',
  data: {
    message: 'Hello Vue!'
  }
})

Vue Components

Components are one of the most powerful features of Vue.js. They help you extend basic HTML elements to encapsulate reusable code.

Vue.component('my-component', {
  template: '<div>A custom component!</div>'
})

new Vue({
  el: '#app'
})

Module 2: Vue CLI and Vue Router

Setting up a Project with Vue CLI

Vue CLI is a full system for rapid Vue.js development, providing interactive project scaffolding via @vue/cli, a runtime dependency (@vue/cli-service) that is upgraded together with the core Vue CLI, and a full GUI to create and manage Vue.js projects.

npm install -g @vue/cli
# or
yarn global add @vue/cli

Introduction to Vue Router

Vue Router is the official router for Vue.js. It deeply integrates with Vue.js core to make building Single Page Applications with Vue.js a breeze.

const router = new VueRouter({
  routes: [
    { path: '/foo', component: Foo },
    { path: '/bar', component: Bar }
  ]
})

const app = new Vue({
  router
}).$mount('#app')

Module 3: State Management with Vuex

Introduction to Vuex

Vuex is a state management pattern + library for Vue.js applications. It serves as a centralized store for all the components in an application, with rules ensuring that the state can only be mutated in a predictable fashion.

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

Actions and Getters in Vuex

Actions are similar to mutations, the differences being that: Instead of mutating the state, actions commit mutations. Actions can contain arbitrary asynchronous operations.

const store = new Vuex.Store({
  state: {
    count: 0
  },
  mutations: {
    increment (state) {
      state.count++
    }
  },
  actions: {
    increment ({ commit }) {
      commit('increment')
    }
  }
})

Module 4: Components and Props

Vue Components

Components are one of the most powerful features of Vue. They help you extend basic HTML elements to encapsulate reusable code.

Vue.component('button-counter', {
  data: function () {
    return {
      count: 0
    }
  },
  template: '<button v-on:click="count++">You clicked me {{ count }} times.</button>'
})

Props in Vue

Props are custom attributes you can register on a component. When a value is passed to a prop attribute, it becomes a property on that component instance.

Vue.component('blog-post', {
  props: ['title'],
  template: '<h3>{{ title }}</h3>'
})

Module 5: Advanced Vue Features

Mixins in Vue

Mixins are a flexible way to distribute reusable functionalities for Vue components.

var myMixin = {
  created: function () {
    this.hello()
  },
  methods: {
    hello: function () {
      console.log('hello from mixin!')
    }
  }
}

var Component = Vue.extend({
  mixins: [myMixin]
})

Render Functions & JSX

Vue recommends using templates to build your HTML in the vast majority of cases. However, in some scenarios, you may need the full programmatic power of JavaScript. That’s where you can use the render function, a closer-to-the-compiler alternative to templates.

new Vue({
  el: '#app',
  render: function (createElement) {
    return createElement(App)
  }
})
