What work is required to create vue

Vue is a popular JavaScript framework that is widely used to develop web applications. Vue is lightweight, easy to learn, and efficient, so it has become one of the best choices in front-end development. To create a Vue application, you need to do the following five things.

1. Install Vue
Before you start creating a Vue application, you need to install Vue. Vue can be installed via CDN and the npm package manager. Vue provides a command line tool, Vue CLI, which simplifies the creation process of Vue projects. The installation method using the npm command is as follows:

npm install vue

After the installation is completed, you can use the following code to verify whether the installation is successful.

import Vue from 'vue'
console.log(Vue)

If you see the Vue object in the console, Vue is installed successfully.

2. Choose an integrated development environment
Choosing a suitable integrated development environment (IDE) can improve development efficiency. IDEs used in Vue include WebStorm, Visual Studio Code, etc. These commonly used IDEs support Vue very well and provide many useful features such as code auto-completion, breakpoint debugging, etc. The advantage of using an IDE is that it can speed up the development of Vue applications and help developers handle errors quickly.

3. Create a Vue instance
In Vue, each application is a Vue instance. Before creating a Vue instance, you need to define the components rendered by the Vue instance. A Vue component is a part of an application, similar to a block or module, with its own templates, styles, and behaviors. In a standard Vue application, there is a root component that acts as the parent for all other components.

Vue components are created by the Vue.extend() or Vue.component() method. When using Vue.extend(), you need to pass an object that contains everything needed to define the component:

var MyComponent = Vue.extend({
  template: '<div>A custom component!</div>'
})

With the Vue.component() method, you can directly define local components.

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

After creating a component, the Vue instance can use the component.

new Vue({
  el: '#app',
  components: {
    'my-component': MyComponent
  }
})

This code creates a Vue instance and sets the root component to MyComponent. Now, this component will be rendered inside the #app element.

4. Define Vue routes
In Vue applications, it is very important to define routes. Routing uses a Single Page Application (SPA) approach to handle user interaction with different pages. This solution has many advantages, including smoother page jumps, faster page loading, and a better user experience. Vue Router is a lightweight routing solution that is scalable and easy to use.

When creating a Vue application, you need to install Vue Router using the Vue CLI. Once installed, routes can be defined and linked to specific pages. Vue Router uses a Vue instance and the required modules to create a router object. Finally, the Vue application can use the created route object to render specific pages.

5. Use Vuex for state management
Finally, Vue applications need to use Vuex for state management. Vuex provides a state management pattern that helps manage all the state in the application, such as user authentication, shopping cart contents, etc. When using Vuex, you create a store in your Vue application, send actions to change state, and call mutations to update the store. Store uses properties and calculations from Vue components to display state to display the desired content in your Vue application.

Summary
Vue is one of the modern JavaScript frameworks that can help developers develop web applications quickly and efficiently. When creating a Vue application, you need to install it, choose an IDE, create a Vue instance, define routes, and use Vuex for state management. Each of these steps is a critical step in creating a Vue application and must be followed strictly in the following five steps.
