Live Server is a popular web extension tool used by developers to create and test websites in real-time. It provides a convenient way to view changes instantly without the need for manual refreshing. With Live Server, you can save time and effort during the development process.

What is Live Server?
Live Server is a lightweight extension for Visual Studio Code that enables developers to create a local development server and preview their web pages in real-time. It eliminates the need to manually refresh the page every time you make a change in your HTML, CSS, or JavaScript code.

How does Live Server work?
Once you have installed Live Server, simply right-click on your HTML file and select “Open with Live Server” from the context menu. This will start a local server, and your default browser will open automatically with the live version of your web page.

As you make changes to your code and save the file, Live Server automatically refreshes the browser window, allowing you to see the updates instantly. This immediate feedback loop can greatly enhance your productivity by reducing the time spent switching between code editor and browser.

Live Server offers several useful features that make it an essential tool for web developers:

  • Auto-refresh: Whenever you save changes in your HTML, CSS, or JavaScript files, Live Server automatically refreshes the browser window.
  • Error notifications: If there are any syntax errors in your code, Live Server will display error notifications in the browser console.
