Visual Studio Code: A Power User’s Guide

Michael Wanyoike

In this guide, you’ll learn how to take advantage of Visual Studio Code to supercharge your development workflow.

This article is written for Visual Studio Code beginners, and users looking to get more out of the app. VS Code, as it’s commonly known, is considered a “lightweight” code editor. In comparison with full integrated development environment (IDE) editors which occupy gigabytes of disk space, VS Code uses less than 200MB when installed.

Despite the “lightweight” term, Visual Studio Code offers a massive number of features which keep increasing and improving with every new update. For this guide, we’ll cover the most popularly used features. Every programmer has their own toolset that they update whenever they discover new workflows. If you want to learn every tool and feature VS Code has to offer, check out their official documentation. In addition, you may want to keep track of updates for new and improved features.


In order to follow this guide, you need to be proficient in at least one programming language and framework. You also need to be conversant with versioning your project code with git. You’ll also need to have an account with a remote repository platform such as GitHub. I recommend you setup SSH Keys to connect with your remote repo.

We’ll use a minimal Next.js project to demonstrate VS Code features. If you’re new to this, don’t worry — the focus of the guide isn’t the framework or language used. You can transfer the skills we’ll teach to any language and framework you work with in Visual Studio Code.

A Bit of History

Not so long ago, these were the fully integrated development environments on offer:

These platforms provide the complete development workflow, from coding to testing and deployment. They analyze code, highlight errors, and have all sorts of other features that provide assistance. They also contain plenty of features that most developers don’t use, though they are essential for some teams. As a result, these platforms took a lot of disk space and were slow to start up. Many developers preferred using advanced text editors such as emacs and vim to write their code in.

Soon, a new crop of platform independent code editors arrived. These lightweight editors provided many features that were previously exclusive to IDEs. I’ve listed them below in the order they were released:

Mac developers had access to TextMate, which was released in October 2004. The snippets system used by all of these editors originated from TextMate. According to a developer survey done by Stack OverFlow in 2019, Visual Studio Code is the most popular code development environment with 50.7% usage. Visual Studio IDE comes second, and NotePad++ comes third.

That’s enough history and stats. Let’s show you how to use Visual Studio Code’s features.

Setup and Updates

Visual Studio Code’s package installer is less than 100MB and consumes less than 200MB when fully installed. When you visit the download page, it will detect your operating system and offer you the correct download link.

Updating VS Code is easy. When an update is available, it displays a notification prompt. For Windows users, you’ll have to click on the notification to download and install the latest version. The download process occurs in the background while you’re working. When it’s ready to install, a restart prompt will appear. Clicking this will install the update for you and restart VS Code.

For Ubuntu-based distributions, clicking on the update notification will simply open the website for you to download the latest installer. A much easier way is simply running sudo apt update && sudo apt upgrade -y. This will update all installed Linux packages including Visual Studio Code. The reason this works is because VS Code added its repo to your package repo registry during the initial installation. You can find the repo information on this path: /etc/apt/sources.list.d/vscode.list.

User Interface

Let’s first get acquainted with the user interface:

VS Code user interface

Visual Studio Code’s user interface is divided into five main areas which you can easily adjust.

  • Activity Bar: allows you to switch between views: explorer, search, version control, debug and extensions.
  • Side Bar: contains the active view.
  • Editor: this is where you edit files and preview markdown files. You can arrange multiple open files side-by-side.
  • Panel: displays different panels: integrated terminal, output panels for debug information, errors and warnings.
  • Status: displays information about the currently opened project and file. Also contains buttons for executing version control actions, and enabling/disabling extension features.

There’s also the top Menu Bar where you can access the editor’s menu system. For Linux users, the default integrated terminal will probably be the Bash shell. For Windows users, it’s PowerShell. Fortunately, there’s a shell selector located inside the terminal dropdown that will allow you to choose a different shell. If installed, you can choose any of the following:

  • Command Prompt
  • PowerShell
  • PowerShell Core
  • Git Bash
  • WSL Bash

Working with Projects

Unlike full IDEs, Visual Studio Code doesn’t provide project creation or offer project templates in the traditional way. It simply works with folders. On my Linux development machine, I’m using the following folder pattern to store and manage my projects:


The Projects folder is what I refer to as to the workspace. As a freelance writer and developer, I separate projects based on which company I’m working for, and which repo I’m using. For personal projects, I store them under my own fictitious “company name”. For projects that I experiment with for learning purposes, and which I don’t intend to keep for long, I’ll just use a name such as play or tuts as a substitute for {repo-provider}.

If you’d like to create a new project and open it in VS Code, you can use the following steps. Open a terminal and execute the following commands:

$ mkdir vscode-demo
$ cd vscode-demo
# Launch Visual Studio Code
$ code .

You can also do this in File Explorer. When you access the mouse context menu, you should be able to open any folder in VS Code.

If you want to create a new project linked to a remote repo, it’s easier creating one on the repo site — for example, GitHub or BitBucket.

GitHub create project

Take note of all the fields that have been filled in and selected. Next, go to the terminal and execute the following:

# Navigate to workspace/company/repo folder
$ cd Projects/sitepoint/github/

# Clone the project to your machine
$ git clone{insert-username-here}/vscode-nextjs-demo.git

# Open project in VS Code
$ cd vscode-nextjs-demo
$ code .

Once the editor is up and running, you can launch the integrated terminal using the keyboard shortcut Ctrl+~ (tilde key). Use the following commands to generate package.json and install packages:

# Generate `package.json` file with default settings
$ npm init -y

# Install package dependencies
$ npm install next react react-dom

Next, open package.json and replace the scripts section with this:

"scripts": {
  "dev": "next",
  "build": "next build",
  "start": "next start"

The entire Visual Studio Code window should look like this:

VS Code run script

Before we look at the next section, I’d like to mention that VS Code also supports the concept of multi-root workspaces. If you’re working with related projects — front-end, back-end, docs etc. — you can manage them all in a single workspace inside one editor. This will make it easier to keep your source code and documentation in sync.

Version Control with Git

Visual Studio Code comes built-in with Git source control manager. It provides a UI interface where you can stage, commit, create new branches and switch to existing ones. Let’s commit the changes we just did in our project. On the Activity bar, open the Source Control Panel and locate the Stage All Changes plus button as shown below.

VS Code source control

Click on it. Next, enter the commit message “Installed next.js dependencies”, then click the Commit button at the top. It has the checkmark icon. This will commit the new changes. If you look at the status located at the bottom, you’ll see various status icons at the left-hand corner. The 0 ↓ means there’s nothing to pull from the remote repo. The 1 ↑ means you’ve got one commit you need to push to your remote repo. Clicking on it will display a prompt on the action that will take place. Click OK to pull and push your code. This should sync up your local repo with the remote repo.

To create a new branch or switch to an existing branch, just click the branch name master on the status bar, left bottom corner. This will pop up a branch panel for you to take an action.

VS Code branch actions

Do check out the following extensions for an even better experience with Git:

Support for a different type of SCM, such as SVN, can be added via installing the relevant SCM extension from the marketplace.

Creating and Running Code

On the Activity Bar, head back to the Explorer Panel and use the New Folder button to create the folder pages at the root of the project. Select this folder and use the New File button to create the file pages/index.js. Copy the following code:

function HomePage() {
  return <div>Welcome to Next.js!</div>;

export default HomePage;

With the Explorer Panel, you should see a section called NPM Scripts. Expand on this and hover over dev. A run button (play icon) will appear next to it. Click on it and this will launch a Next.js dev server inside the Integrated Terminal.

VS Code run script

It should take a few seconds to spin up. Use Ctrl + Click on the URL http://localhost:3000 to open it in your browser. The page should open successfully displaying the “Welcome” message. In the next section, we’ll look at how we can change Visual Studio Code preferences.

User and Workspace Settings

To access VS Code preference settings, use the shortcut key Ctrl + ,. You can also access it via the menu command like this:

  • On Windows/Linux – File > Preferences > Settings
  • On macOS – Code > Preferences > Settings

By default, a Settings editor graphical interface should appear. It helps users make changes to preferences easily, as there are thousands of editable settings that are available. The Settings editor provides user friendly names and description for what each setting does. In addition, related settings have been grouped together and there’s a search bar for locating a specific setting.

VS Code settings panel

When changing settings using the editor, pay attention to the active scope at the top. Take note that not all settings can be configured via the graphical interface. For that, you have to edit the file settings.json directly. As you scroll down the Settings editor, you’ll come across a shortcut that will take you to this file.

There are two different scopes that Visual Studio Code settings are classified under:

  • User Settings: Settings are stored under user account. They will take effect on all projects your work on.
  • Workspace: Settings are stored within project or workspace folder. They will apply only in that specific project.

Depending on your platform, you can locate VS Code’s user setting in the following locations:

  • Windows: %APPDATA%\Code\User\settings.json
  • macOS: $HOME/Library/Application Support/Code/User/settings.json
  • Linux: $HOME/.config/Code/User/settings.json

For Workspace, simply create a folder .vscode at the root of your project. Then create the file settings.json inside this folder. If working with the Settings editor panel, it will do this for you automatically when you change settings under the Workspace scope. Here’s a subset of the global settings I prefer to work with:

  "editor.minimap.enabled": false,
  "window.openFoldersInNewWindow": "on",
  "diffEditor.ignoreTrimWhitespace": false,
  "files.trimTrailingWhitespace": true,
  "javascript.updateImportsOnFileMove.enabled": "always",
  "workbench.editor.enablePreview": false,
  "workbench.list.openMode": "doubleClick",
  "window.openFilesInNewWindow": "default",
  "editor.formatOnPaste": true,
  "editor.defaultFormatter": "esbenp.prettierVS Code",
  "editor.formatOnSave": true,
  "editor.tabSize": 2,
  "explorer.confirmDelete": false

I tend to work with multiple projects simultaneously, hence the setting window.openFoldersInNewWindow allows me to open new project folders without closing (replacing) the active one. For editor.defaultFormatter, I’ve set it to Prettier, which is an extension I have installed. We’ll discuss this in a later section shortly. Next, let’s look at language associations.

Language Association

I do a lot of projects using React. Lately, most React frameworks generate components use the .js extension instead of .jsx. As a result, formatting and syntax colorization becomes a problem when you start writing JSX code. To fix this, you need to associate .js files with JavaScriptReact. You can easily do this by changing Language Mode via the Ctrl + Shift + P command panel. You can also update settings.json by adding this configuration:

  "files.associations": {
    "*.js": "javascriptreact"

Next time you open a JS file, it will be treated as a React JSX file. I’ve specified this in my global settings since I often work with React projects. Unfortunately, doing this breaks a built-in feature called Emmet. It’s a popular plugin that helps developers autocomplete HTML and CSS code in a very intuitive way. You can fix this issue by adding the following configuration in settings.json:

  "emmet.includeLanguages": {
    "javascript": "javascriptreact"

Next time you have trouble activating Emmet for a particular file extension or language, check to see if it can be resolved by adding the language association in emmet.includeLanguages. For more information, check out the official documentation for VS Code Emmet.

Keyboard Shortcuts

So far, we’ve covered two keyboard shortcuts:

  • Ctrl + ,: Open settings
  • Ctrl + Shift + P: Open command palette

The Command Palette provides access to Visual Studio Code’s entire functionality including keyboard shortcuts for common operations. If you install an extension, any manually triggered actions will be listed here. However, for extensions such as Prettier and Beautify, they’ll use the same Format command. Visual Studio Code also has its own built-in formatter plugin. To specify which plugin should execute the action, you need to go to the Settings editor and change the Default Formatter configuration. Here’s an example of how I’ve set it in mine:

  "editor.defaultFormatter": "esbenp.prettierVS Code"

You can also specify a different formatter for a specific language mode. Here are several more keyboard shortcuts you need to memorize:

  • Ctrl + P will let you navigate to any file or symbol by typing its name
  • Ctrl + Tab will cycle you through the last set of files opened
  • Ctrl + Shift + O will let you navigate to a specific symbol in a file
  • Ctrl + G will let you navigate to a specific line in a file

Here are my favorite commands I use often while writing code:

  • Ctrl + D: press multiple times to select identical keywords. When you start typing, it renames all the selected keywords
  • Ctrl + Shift + Up/Down: Add Cursor above or below in order to edit multiple lines at once
  • Alt + Shift + Click: Add Cursor at multiple locations in order to edit in different sections of code simultaneously
  • Ctrl + J: Add 2 or more lines into one. Works perfectly if you’ve a formatter active as you edit code
  • Ctrl + F: Search for a keyword in current file
  • Ctrl + H: Search and replace in current file
  • Ctrl + Shift + F: Search in all files

If you visit the Menu options, you’ll find shortcut keys for most commands. Personally, I’ve never gotten used to some of the default shortcut keys that come with Visual Studio Code due to using editors such as Atom for a long time. The solution I found was simply to install the Atom Keymap. This allows me to use the shortcut key Ctrl + \ to toggle the Side Bar. If you’d like to edit the keyboard bindings yourself, simply go to the menu under File > Preferences > Keyboard Shortcuts. (Code > Preferences > Keyboard Shortcuts on macOS).

Code Editor Features

In this section, we’ll quickly look into the various developer-friendly features Visual Studio Code provides to help you write faster, cleaner and more maintainable code.


This is a popular feature also known as “code completion” or autocomplete. Out of the box, VS Code provides Intellisense for:

  • JavaScript, TypeScript
  • HTML
  • CSS, SCSS and Less

As you type your code, a pop with a list of possible options will appear. The more you type, the shorter the list gets. You can press Enter or Tab once your intended keyword is highlighted to autocomplete your code. Pressing Esc will remove the popup. Inserting a . at the end of a keyword or pressing Ctrl + space bar will trigger the IntelliSense popup to appear.

If you’re working with a language that is not supported out of the box, you can install a language extension from the marketplace to activate IntelliSense for your desired programming language. Check out the official docs to learn more on how you can customize IntelliSense.


Typing repetitive code such as if statements, for loops and component declaration can be a bit tiring. You might find yourself copying and pasting code to work faster. Fortunately, Visual Studio Code offers a feature called Snippets, which are simply templates of code. For example, instead of typing console.log, just type log and IntelliSense will prompt to insert the snippet for you.

There are many snippets you can access as long as you’ve memorized the shorthand or keyword that triggers snippet insertion. Since you’re new to this, you can access a list of all snippets available via Command Palette > Insert Snippets:

insert snippets

Scroll up and down to view the entire list. Take note that most snippets have tabstops that allow you to replace the relevant sections of code when you insert them. You can find more snippet extensions in the marketplace. You can also create your own. This article shows you how to do both. You can check out the official docs for more information on how to define your own snippets.


Often when typing or pasting code from different sources, we tend to mix coding styles. For example:

  • indenting with space vs tabs
  • ending with semicolon
  • double quotes or single quotes

Formatting is important, as it makes the code readable. However, it can be time consuming when you come across large sections of unformatted code. Luckily, Visual Studio Code can perform formatting for you with a single command. You can execute the formatting command via the Command Palette. Visual Studio Code supports formatting for the following languages out of the box:

  • JavaScript
  • TypeScript
  • JSON
  • HTML

You can customize Visual Studio Code’s formatting behavior by changing the following settings to true or false:

  • editor.formatOnType: format the line after typing
  • editor.formatOnSave: format a file on save
  • editor.formatOnPaste: format the pasted content

However, the built-in formatters may not conform to your style of coding. If you’re working with frameworks such as React, Vue or Angular, you’ll find that the built-in formatters tend to mess up your code. You can fix this by disabling formatting for a specific language:

"html.format.enable": false

However, the best solution is to install a formatter extension from the marketplace. My favorite is [Prettier]( Code), as it supports a huge number of languages including:

  • Flow · JSX · JSON
  • CSS · SCSS · Less
  • Vue · Angular
  • GraphQL · Markdown · YAML

After installing it, you’ll need to set it as the default formatter:

  "editor.defaultFormatter": "esbenp.prettierVS Code",
": {
    "editor.defaultFormatter": "esbenp.prettierVS Code"

It’s also recommended you install prettier package locally as a dev dependency:
npm install prettier -D --save-exact

The default formatting options Prettier enforces may work out for you. If not, you can customize by creating a .prettierrc configuration file either at the root of your project or in your home directory. You can place your custom formatting rules here. Here’s an example:

  "trailingComma": "all",
  "tabWidth": 2,
  "semi": false,
  "singleQuote": true

Feel free to check out other formatting extensions. However, you’ll find Prettier to be the most popular.


A Lint, or Linter is a tool that analyzes your code and checks for syntax errors, styling issues, calls to undeclared variables, usage of deprecated functions, misuse of scope and many other issues. Visual Studio Code doesn’t come shipped in with any Linter. However, it does make it easy setting up one for the programming language you’re using. For example, if you’re working on new Python project, you’ll get a prompt to install one for you. You can also open the Command Palette (Ctrl + Shift + P) and select the Python: Select Linter command.

For JavaScript, you’ll need to install an extension such as ESLint which is the most popular. This extension requires you to install ESLint as a dev dependency. You may also need one or more ESLint plugins that will help you lint the coding style and framework you’re using. You can check out our guide on how to configure ESLint. There are also other linter tools you can check out. My recommendation is to go with ESLint as it’s easier to configure and supports more JavaScript styles and frameworks.

Once you’ve set up the linting tool, VS Code will automatically lint your code every time you save the file. You should also update your package.json scripts to include a command for running the lint tool.


If you use print statements to debug, you should cease and desist as there’s a better way to debug your code. With VS Code, you can set breakpoints and inspect variables while your code is running.
