How to implement navigation in Vue

Vue is a JavaScript framework suitable for developing single-page applications, so an important part is navigation. In Vue, you can use Vue Router to implement navigation. Here are the steps on how to implement navigation in Vue.

Step One: Install Vue Router

You can use npm or yarn to install Vue Router in your Vue project. In the terminal or command line, enter the following command:

npm install vue-router -save 或
yarn add vue-router

Step 2: Create a Vue Router instance

In the project, you need to create a Vue Router instance. Open the main.js file in the project and enter the following code:

import Vue from 'vue';
import VueRouter from 'vue-router';

Vue.use(VueRouter);

const router = new VueRouter({
  routes: [
    {
      path: '/',
      name: 'home',
      component: Home
    },
    {
      path: '/about',
      name: 'about',
      component: About
    }
  ]
});

What you do is import Vue and Vue Router, and create a Vue Router instance and define routes. Please note that routing is an attribute of the Vue Router instance, and the path attribute is used to specify the routing path, the name attribute is used to specify the route name, and the component attribute is used to specify the component, such as Home, About, etc.

Step 3: Set routing

In the Vue project, you need to set routing. Open the App.vue file and add the following code:

<template>
  <div>
    <nav>
      <router-link>Home</router-link>
      <router-link>About</router-link>
    </nav>
    <router-view></router-view>
  </div>
</template>

What it does is add a link in the navigation bar using the router-link tag. The path is specified using the to attribute, in this example we have a link to "/" and "/about". In addition, use the router-view component to load the selected routing component.

Step 4: Use routing

Now that you have created a Vue Router instance, set up routing and links, you can use routing in your components. Open the Home.vue file and add the following code:

<template>
  <div>
    <h1 id="Home-Page">Home Page</h1>
    <p>Welcome to my home page!</p>
  </div>
</template>

Now open About.vue and add the following code:

<template>
  <div>
    <h1 id="About-Page">About Page</h1>
    <p>Welcome to my about page!</p>
  </div>
</template>

Now open main.js and add the following code:

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

Note that we have injected the router instance into the Vue instance and used the $mount() method to mount the Vue instance on the # app element of the application.

Now restart your Vue application and navigate to the "/" and "/about" paths in your browser, you will see the Home and About pages.

In this article, you learned how to implement navigation in a Vue application. The steps include installing Vue Router, creating a Vue Router instance, setting up routing, and using routing. Now you can add navigation in your Vue application to enable users to easily navigate the application and access the required pages.
