Visual Studio Code — Development Environment & Programming

Microsoft's free code editor that provides extensions, terminal, and Git integration in a single window.

Basic information

What is this program?

Visual Studio Code (VS Code) is a free code editor distributed by Microsoft. It starts as a lightweight editor, but with extensions, it becomes a de facto development environment that handles language servers, debuggers, and even container development.

It has a built-in terminal, Git, and debugger, and with the Remote-SSH extension you can open code on a remote server as if editing locally. It is also widely used by server administrators when editing configuration files and scripts.

What problems does it solve?

• ('In code editing', 'when working with scripts and configuration files in multiple languages together', 'you can get syntax highlighting, auto-completion, and error marking through extensions.')
• ('In remote server work', 'when you want to edit on a server instead of nano or vim', 'you can edit the server file system locally with Remote-SSH.')
• ('In debugging', 'when you need to trace issues while a script is running', 'you can pause execution with breakpoints and the variables panel to inspect.')

Key features

Intelligent auto-completion

Language server-based code auto-completion and error indication

• Use case: multilingual editing
• Result: check typos and API errors while editing
• Limitations: language-specific extensions must be installed first.

Integrated terminal

Use shell and multiple terminal sessions inside the editor

• Use case: when moving between editing and execution
• Result: edit and run simultaneously with split screen
• Limitations: the shell environment uses the local profile as-is.

Remote-SSH

Use the remote server's file system and terminal through a local UI

• Use case: server development and operations
• Result: set up a remote development environment with just an SSH connection
• Limitations: pay attention to server-side extension installation and resource usage.

Git integration

Handle diff, commits, and branches through the UI

• Use case: source control
• Result: basic Git workflow without terminal commands
• Limitations: for complex conflict resolution, the terminal may be better.

Installation and execution

Linux (deb)

For Ubuntu and Debian-based systems, download and install the .deb file.

sudo apt install ./code_1.142.0-*.deb

Linux (rpm / Snap)

Install on RPM-based systems or via Snap.

sudo rpm -i code-1.142.0-*.rpm   # Fedora/RHEL
sudo snap install code --classic   # Snap

Windows / macOS

Download and install the official installation file.

# code.visualstudio.com/download
# Windows: User/System Setup.exe, macOS: Universal .zip/.dmg

Practical usage examples

Open a folder and get started

When you open a project folder with File > Open Folder, the tree, terminal, and Git status appear together.

File > Open Folder… > /home/jw/project
Shortcut: Ctrl+K Ctrl+O

Remote SSH connection

After installing the Remote-SSH extension, select Connect to Host from the green bar at the lower left to connect to a server.

Ctrl+Shift+P > Remote-SSH: Connect to Host

Terminal and execution

Use Ctrl+` to open the integrated terminal and handle build, run, and Git commands.

Ctrl+`  →  Terminal opens
$ git status
$ python3 app.py

Pros and limitations

Pros

• Free, lightweight, and fast to start (less overhead than a full IDE)
• A very large extension ecosystem — supports most languages and tools
• Supports remote workflows such as Remote-SSH and container development
• Good portability with the same UI on Windows, macOS, and Linux

Considerations before use

• Large-project-specific features may be lacking compared to commercial IDEs like JetBrains.
• Installing many extensions slows down memory and startup speed.
• Because it is a Microsoft product, some environments require corporate policy and license review.
