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

With the development of cloud computing and open source technology, the Linux operating system is becoming more and more popular among programmers and developers. On Linux, Visual Studio Code (VS Code for short), as a powerful code editor, has gradually become one of the preferred tools for developers. This article will introduce how to use VS Code for back-end development on Linux and give some recommended configurations.

1. Install VS Code

First, you need to install VS Code on Linux. You can download the installation package for Linux from the official website and install it according to the prompts. After the installation is complete, you can start VS Code.

2. Install Extensions

VS Code provides many powerful functions and tools through a rich extension ecosystem, making back-end development more convenient and efficient. Here are some recommended extensions that you can install by searching for and installing them in VS Code’s extensions panel:

• Python: This is a must-have extension if you use Python for backend development. It provides code completion, syntax checking, debugging support and other functions.
• Java: If you use Java for backend development, you can install the Java extension. It supports project management, code completion, debugging and other functions.
• Node.js: If you use Node.js for backend development, you can install the Node.js extension. It provides running, debugging, testing and other related tools.
• Docker: If you use Docker for application containerization, you can install the Docker extension. It provides integration with Docker to facilitate you to manage and operate containers.
• Git: As a version control tool, the Git extension provides you with integration with Git, making code submission, pull and branch management more convenient.

3. Configuring the debugger

The debugger is one of the indispensable tools for back-end development. In VS Code, you can configure the corresponding debugger according to your own development language. Taking Python as an example, you can press the F5 key to enter debugging mode, and then select Python (or other language) as the debugging environment. Next, you need to create a launch.json file in the .vscode folder to configure the behavior of the debugger.

Taking Python as an example, the following is a simple launch.json configuration example:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Python: Debug",
      "type": "python",
      "request": "launch",
      "program": "${file}",
      "console": "integratedTerminal"
    }
  ]
}

The above configuration will start the Python interpreter in the integrated terminal and execute the current file. You can adapt and expand it to suit your needs.

4. Using the terminal

In back-end development, the terminal is one of the essential tools. VS Code provides an integrated terminal function that can execute terminal commands directly in the editor. You can open the terminal panel by pressing the Ctrl ` key (the backtick key) and execute the corresponding command in it. For Linux systems, you can use any terminal command you are familiar with, which makes back-end development in VS Code more convenient.

5. Using code snippets

In order to improve development efficiency, VS Code supports code snippets (snippet). A code snippet can be a template for a section of code that is expanded into a complete block of code using simple keywords. In back-end development, we often need to enter repeated code snippets, such as function definitions, model declarations, etc. By defining and using code snippets, you can save a lot of time and effort.

Taking Python as an example, you can open the preferences of VS Code and select User Snippets. In a Python snippet file, you can define your own code snippet, as shown below:

{
  "Python": {
    "model": {
      "prefix": "model",
      "body": [
        "class ${1:Model}(models.Model):",
        "    ${2:field_name} = models.${3:CharField}(max_length=${4:255})"
      ],
      "description": "Model snippet"
    }
  }
}

The above code defines a code snippet named model. You can enter model in the editor and then press the Tab key to expand to the complete model code.

Summary

With the above configuration, you can use Visual Studio Code on Linux for back-end development and improve development efficiency. Of course, these are just some recommended configurations, and you can adjust and expand them according to your needs and habits. I hope this article can help you use VS Code for back-end development on Linux!
