Let's talk about the basic process of Vue entering new routing

With the increase in the complexity and functionality of web applications, front-end frameworks have developed rapidly, and vue, as one of them, plays an important role in the front-end framework. When developing web applications, we often encounter situations where we need to enter new routes. Therefore, this article will introduce the basic process of Vue entering a new route.

1. Dynamic routing and static routing

In vue, there are dynamic routing and static routing. Dynamic routing refers to passing parameters in the URL, while static routing refers to not passing parameters in the URL. Among them, static routing is more commonly used than dynamic routing.

2. Basic use of vue routing

vue-router is a simplified version of the vue framework. It provides a complete routing solution for creating SPA (single page application). It allows us to render different components through URLs. In this process, the routing module plays an important role. Let's take a look at a basic vue routing code:

import Vue from 'vue'
import Router from 'vue-router'
import Home from './views/Home.vue'

Vue.use(Router)

export default new Router({
  routes: [
    {
        path: '/',
        name: 'home',
        component: Home
    },
    {
        path: '/about',
        name: 'about',
        component: () => import('./views/About.vue')
    }
  ]
})

In the above code, we first introduced the vue-router library and created a routing instance. In the routes attribute, we define two different routes, Home and About. Home routing is a static routing, while About routing is a dynamic routing, but the difference is that we use the lazy loading function, which can help us improve the performance of the application.

3. Navigation in vue routing

In vue routing, navigation refers to the process of jumping from one route to another. Vue Router provides the router-link component as the entry point for navigation. router-link is a routing link component that allows us to switch between components in our application without refreshing the entire page. In the example below, we use to create a navigation link to the about page.

<router-link to="/about">About</router-link>

4. Hooks in vue routing

In vue routing, Vue Router provides several methods, called life cycle hooks, which can be used to perform specific tasks. Using these hooks for routes allows us to execute code before route navigation, after route navigation, and before components are rendered. The following are some commonly used hooks:

1. beforeEach: executed before routing jump, which can be used for authentication judgment.
2. afterEach: Executed after routing jump, can be used for page middleware processing.
3. beforeRouteEnter: Executed when the current route is about to be jumped to. It can be used to preload and process data for the upcoming page.

5. Programmatic navigation in vue routing

In many cases, we want to use programmatic navigation to a new URL, which is called programmatic navigation. Programmatic navigation refers to using code within a routing function to navigate to a new URL. Vue Router provides the $router.push method to implement programmatic navigation, which accepts a URL path as a parameter. Here is an example of using programmatic navigation:

this.$router.push('/about')

Finally, vue routing plays a very important role in the development of web applications. In this article, I cover the basic process of entering a new route, which includes dynamic routing, static routing, basic usage of routes, navigation in routes, hooks, and programmatic navigation. These basic knowledge are an integral part of Vue development, and I hope they can help you better understand the basic use of Vue routing.
