vue.jsHow do I use hot reload with Vue.js?

Hot reloading is a feature of Vue.js that allows for real-time updates to the code without having to manually refresh the page. It works by watching the source code for changes and then automatically reloading the page when a change is detected. Here's an example of how to use it:

// main.js
import Vue from 'vue'
import App from './App.vue'

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

To enable hot reloading, you need to add the --hot flag to the command when running your application. For example, if you are using the Vue CLI, you would run the following command:

vue serve main.js --hot

This will start the development server with hot reloading enabled. Now, whenever you make a change to the code, the page will automatically reload with the new changes.

Code explanation

1. import Vue from 'vue' - imports the Vue library
2. import App from './App.vue' - imports the App component
3. render: h => h(App) - renders the App component
4. vue serve main.js --hot - starts the development server with hot reloading enabled
