Router-view is a component in Vue.js that is used to render the component associated with the current route. It is a placeholder component that is used to render the component associated with the current route. When the URL changes, router-view re-renders the component associated with the new route. It is a crucial component in building single-page applications (SPAs) using Vue.js and provides a seamless way of rendering components based on the current route.
Router-view is used in conjunction with the Vue Router library, which provides the routing functionality for Vue.js applications. The Vue Router library allows developers to define routes for their application and associate a component with each route. When a user navigates to a particular route in the application, Vue Router renders the associated component inside the router-view component.
Here is an example of how to use router-view in a Vue.js application:
```
<template>
<div id="app">
<router-view></router-view>
</div>
</template>
<script>
import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)
const router = new VueRouter({
routes: [
{ path: '/', component: Home },
{ path: '/about', component: About },
{ path: '/contact', component: Contact }
]
})
const Home = { template: '<div>Home</div>' }
const About = { template: '<div>About</div>' }
const Contact = { template: '<div>Contact</div>' }
export default {
router
}
</script>
```
In this example, router-view is used to render the component associated with the current route. The Vue Router library is used to define three routes: '/' for the Home component, '/about' for the About component, and '/contact' for the Contact component. When a user navigates to a particular route, the associated component is rendered inside the router-view component.
