How to use Vue Router to generate and manage dynamic routes?

Vue Router is the official routing manager of Vue.js, which can help us implement routing functions in single-page applications (SPA). Through Vue Router, we can realize the generation and management of dynamic routes, and more flexibly control route jumps when dealing with complex business scenarios. This article will introduce how to use Vue Router to generate and manage dynamic routes, with code examples.

1. Install and configure Vue Router

Before you begin, you need to install Vue Router. You can install Vue Router through the following command:

npm install vue-router --save

After the installation is complete, configure it in the main.js file of the project:

import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App.vue'

Vue.use(VueRouter)

const router = new VueRouter({
  mode: 'history',
  routes: [
    // 这里定义初始路由
  ]
})

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

In the above code, we first import Vue and VueRouter, and then Enable Vue Router via Vue.use(VueRouter). During the Vue instantiation process, the router instance is injected into the Vue instance. Among them, the initial route can be defined in the routes array.

2. Create dynamic routing

To realize the generation and management of dynamic routing, we first need to create dynamic routing.

Before creating dynamic routing, do some preparation work:

• Create a folder in the project to store dynamic routing configuration, such as src/router/ route-config/.
• Create a js file in this folder to store dynamic routing configuration, such as route-config.js.
• Define the configuration information of dynamic routing in this file.

The specific code example is as follows:

const RouteConfig = [
  {
    path: '/user/:id',
    component: () => import('@/views/User.vue'),
    meta: {
      requireAuth: true
    }
  },
  // 其他动态路由配置...
]

export default RouteConfig

In the above code, we define a dynamic routing configuration information, which includes path path, component component and meta metadata.

3. Generation and management of dynamic routes

In the configuration of Vue Router, we can generate and manage dynamic routes through router.addRoutes().

In the main file of the project, such as src/main.js, we can import dynamic routing configuration and use router.addRoutes() to dynamically Generate and manage routes.

The specific code examples are as follows:

import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App.vue'
import RouteConfig from './router/route-config/route-config.js'

Vue.use(VueRouter)

const router = new VueRouter({
  mode: 'history',
  routes: [
    // 这里定义初始路由
  ]
})

// 动态生成和管理路由
router.addRoutes(RouteConfig)

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

In the above code, we imported the dynamic routing configuration RouteConfig, and then passed router.addRoutes() to dynamically generate and manage routes.

So far, we have completed the generation and management of dynamic routing using Vue Router.

Summary:

The generation and management of dynamic routes through Vue Router allows us to control route jumps more flexibly and is suitable for complex business scenarios. When using Vue Router, we need to install and configure it, create dynamic routes and manage it. I hope this article can help you use Vue Router to generate and manage dynamic routes.
