What technology is used in vue development?

In the field of front-end development, Vue.js is a highly respected framework. Vue.js is characterized by its ease of use and rich ecosystem, especially when it comes to building single-page applications (SPA). During the development process of Vue.js, some technologies need to be used to improve development efficiency, which will be introduced in detail below.

1. ES6

Vue.js can be used well in combination with ES6. The new features of ES6 make Vue code easier to read and write. ES6's new operators, changes in declaration methods such as var let, template strings, and class definition methods can make code ideas clearer. For example, the emergence of arrow functions and destructed assignment makes it easier for developers to solve the scope problem of function execution when writing code. In addition, there are async/await, class definitions, iterators, Promise, etc.

2. Webpack

Webpack is an essential technology that should be learned during front-end development. It provides the required customized compilation process for front-end projects. Vue.js is developed based on the component development model, and each Vue component is an independent module. The "modularization" idea used by Webpack allows different components to be loaded as modules, realizing interdependence between components, improving code reusability and reducing duplicate code.

Webpack can be used to manage dependency packages during development, packaging, splitting code, compressing code, hot loading, etc. It can also convert various files into JS modules. In Vue.js applications, Webpack is often used to build Vue components, render templates, compress code, improve application performance, and more.

3. Vue-cli

Vue-cli is a scaffolding tool for quickly generating Vue projects. It has built-in pre-installed development tools such as Webpack, Vue-router, Vuex, and more. Using Vue-cli, you can easily generate a standardized Vue project, thereby improving development efficiency. Taking Vue3.0 as an example, to create a new empty vue project, you only need to use the command line tool to enter:

"vue create my-app"

It will let you choose a preset template , you can also customize which plug-ins you need to install. The template will be pre-installed with some integrated libraries, such as router, vuex, axios, etc., and all dependencies will be configured, allowing you to quickly establish a development environment.

4. Vue-router

Vue-router, as the official router of Vue.js, allows you to manage the routing of applications and implement the routing function of single-page applications. Vue-router makes it easy to manage routing configurations with component thinking, thereby improving the maintainability and scalability of the application.

In the Vue.js application, the routing configuration file of Vue-router is placed under the src/router/index.js file. By introducing the Vue-router module and creating a routing instance, add routing components to it. , thereby realizing page navigation. For example, you can define routes in index.js like this:

import VueRouter from 'vue-router'
import Home from '../views/Home.vue'

const routes = [
{

path: '/',
name: 'Home',
component: Home

}
]

const router = new VueRouter({
routes
})

export default router

5. Vuex

Vuex is the official state management tool in Vue.js. It was developed to solve data management problems between Vue components and make data sharing easier. Vuex provides a unified storage to store all cross-component shared data. The core concept of Vuex is "state". Vuex uses a single state tree as the only data source and uses mutations to control all states to ensure that state changes are maintainable and easy to track.

State changes are processed by submitting a mutation. Use store.commit('mutation') to trigger a mutation. Vuex will also maintain a snapshot of the state tree while tracking the state change record, allowing We can always go back to a previous state.

6. Axios

Axios is a Promise-based HTTP request library, which can provide client data request services. Vue.js is very common when calling back-end data. We always need to obtain data through HTTP requests. In this case, we need to use an HTTP request library. Compared with native ajax and jQuery encapsulated APIs, the advantage of Axios is that it is easier to handle requests, cancel requests, and handle response errors.

Axios can be used as a client in the browser, or it can use Node.js as a server-side proxy to handle HTTP requests.

7. ElementUI

ElementUI is a component library based on Vue.js 2.0. It provides some common UI components, such as buttons, panels, progress bars, etc. Use ElementUI to quickly build consistent and beautiful user interaction interfaces. You can directly install the Element plug-in and introduce related components to easily display, operate and interact with data.

Summary:

The above introduces the technologies that should be mastered and used in the Vue development process. Of course, this is just an introduction to a series of technical points. These technologies have different characteristics and usage scenarios, which require us to use them flexibly and make flexible choices in actual development. At the same time, continuous learning, updating and expansion of knowledge reserves are required to adapt to the challenges of various business and technological changes.
