Recommended configuration for using Visual Studio Code for front-end development on Linux

Introduction:
With the rapid development of front-end development, more and more developers choose Visual Studio Code (VS Code for short) ) as the primary code editor. VS Code is a free and open source lightweight editor that supports a rich set of extension plug-ins and can meet various needs of front-end development.
This article will give the recommended configuration for using VS Code for front-end development on Linux, including installation and configuration steps, and attach some code examples.

1. Install VS Code
Install VS Code on Linux through the following steps:

Open the terminal and enter the VS Code official website: https://code.visualstudio. com/.
Click the "Download for Linux" button to download the Debian package of VS Code.
Enter the following command in the terminal to install VS Code:
```
sudo dpkg -i <vscode-package>.deb
sudo apt-get install -f
```
After the installation is complete, enter the "code" command to start VS Code.

2. Install commonly used extension plug-ins
The extension plug-ins of VS Code greatly enhance its functions. Here are several commonly used extension plug-ins:

ESLint: Plugin for code specification checking.
Installation method: Search for "ESLint" in VS Code and click to install.
Prettier: Plug-in for code formatting, supports multiple languages.
Installation method: Search for "Prettier - Code formatter" in VS Code and click to install.
Live Server: Provides a local development server to render changes to HTML, CSS and JavaScript files in real time.
Installation method: Search for "Live Server" in VS Code and click to install.

Through the installation of the above plug-ins, our development process has been greatly simplified and coding efficiency has been improved.

3. Configure ESLint
For front-end development, writing standardized and clean code is crucial. ESLint is an excellent code specification checking tool that can help us maintain code consistency.
The following are the steps to configure ESLint:

Install ESLint in the project root directory:
```
npm install eslint --save-dev
```
Run the following command in the terminal to generate ESLint configuration file:
```
npx eslint --init
```
Follow the prompts to select the rules for the configuration file. You can use preset rules such as Airbnb and Google, or you can define your own.
Add the following configuration in the settings of VS Code:
```
"editor.codeActionsOnSave": {
 "source.fixAll.eslint": true
}
```
In this way, every time the file is saved, VS Code will automatically call ESLint to check the code specification and try to fix it mistake.

4. Configure Prettier
Prettier is a code formatting tool that can automatically format the code to maintain a consistent style.
The following are the steps to configure Prettier:

Install Prettier in the project root directory:
```
npm install prettier --save-dev
```
Add in the settings of VS Code The following configuration:
```
"editor.defaultFormatter": "esbenp.prettier-vscode",
"[javascript]": {
 "editor.formatOnSave": true
}
```
In this way, every time a JavaScript file is saved, VS Code will automatically call Prettier for code formatting.

5. Use Live Server
Live Server is a very useful extension plug-in that provides a local development server and renders modifications to HTML, CSS and JavaScript files in real time. The following are the steps to use Live Server:

Right-click the project folder in VS Code and select "Open with Live Server" to start the local development server. The default port is 5500.

6. Code Example
Here is a code example of a simple HTML page:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <h1>Hello, world!</h1>
    <script src="script.js"></script>
</body>
</html>

In the above code, style.css and script.js are styles respectively. and script files, which can render page changes in real time through Live Server.

Conclusion:
With the above configuration and steps, we can use Visual Studio Code on Linux for efficient front-end development. Installing commonly used extension plug-ins, configuring code specification checking and code formatting tools, and combining it with the local development server provided by Live Server greatly improves development efficiency and code quality. We hope that readers can further expand and configure it according to their own needs and project characteristics, bringing more convenience and fun to front-end development.
