Vue Router NPM Install

If you are a Vue.js developer, you must have heard about Vue Router. It is the official router for Vue.js and allows you to create SPA (Single Page Application) easily. In order to use Vue Router in your project, you need to install it using NPM (Node Package Manager).

Step 1: Install Node.js and NPM

If you don't have Node.js and NPM installed on your system, you need to install them first. Node.js comes with NPM, so when you install Node.js, NPM gets installed automatically. You can download Node.js from https://nodejs.org/en/download/.

Step 2: Create a Vue.js Project

In order to use Vue Router, you need to create a Vue.js project first. You can create a project using Vue CLI, which is a command-line interface for creating Vue.js projects. If you don't have Vue CLI installed, you need to install it first. You can install it using the following command:

$ npm install -g @vue/cli

This will install Vue CLI globally on your system.

Once you have Vue CLI installed, you can create a new Vue.js project using the following command:

$ vue create my-project

This will create a new Vue.js project with the name "my-project".

Step 3: Install Vue Router

Now that you have created a new Vue.js project, you can install Vue Router using NPM. You can do this using the following command:

$ npm install vue-router

This will install Vue Router and its dependencies in your project's node_modules directory.

Step 4: Import and Use Vue Router

After installing Vue Router, you need to import it in your project and use it. You can do this in your main.js file. Here's an example:

// Import Vue Router
import VueRouter from 'vue-router';

// Use Vue Router
Vue.use(VueRouter);

Once you have imported and used Vue Router, you can define your routes and use them in your components. Here's an example:

// Define routes
const routes = [
  { path: '/', component: Home },
  { path: '/about', component: About },
  { path: '/contact', component: Contact }
];

// Create router instance
const router = new VueRouter({
  routes
});

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

In the above example, we have defined three routes - "/" (Home), "/about" (About), and "/contact" (Contact). We have also created a router instance and passed the routes to it. Finally, we have created a Vue instance and passed the router to it.

That's it! You have successfully installed and used Vue Router in your Vue.js project.
