Basics

Insider Version of VS Code

The VS Code team uses the Insiders version to test the latest features and bug fixes of VS Code. You can use this same version by downloading here.

For Early Adopters - Insiders has the most recent code changes and may lead to the occasional broken build.
Frequent Builds - New builds everyday with the latest bug fixes and features.
Side-by-side install - Insiders installs next to the Stable build allowing you to use either independently.

Getting Started

Open the welcome page to get started with the basics of VS Code. Help -> Welcome.

Includes the interactive playground.

Command Palette

Access all available commands based on your current context.

Mac: cmd+shift+p or f1

Windows / Linux: ctrl+shift+p or f1

Reference keybindings

All of the commands are in the command palette with the associated key binding (if it exists). If you forget what the key binding is use the command palette to help you out.

Customization

There are many things you can do to customize VS Code.

Change your theme
Change your keyboard shortcuts
Tune your settings
Add JSON validation
Create snippets
Install extensions

Check out the full documentation.

Change your theme

Open the command palatte and type "themes". You can install more themes from the extension Marketplace.

Additionally, you can install and change your file icon themes.

Change your keyboard shortcuts

Keyboard Reference Sheets

Download the keyboard shortcut reference sheet for your platform (macOS, Windows, Linux).

Keymaps

Are you used to keyboard shortcuts from another editor? You can install a Keymap extension that brings the keyboard shortcuts from your favorite editor to VS Code. Go to Preferences -> Keymap Extensions to see the current list on the Marketplace. Some of the more popular ones:

Customize your keyboard shortcuts

Open the command palatte and type "Keyboard Shortcuts." You can now add your own keybindings in the file on the right.

See more in the Official Documentation.

Tune your settings

Open settings.json

Mac: cmd+,

Windows / Linux: File -> Preferences -> User Settings

Format on paste

"editor.formatOnPaste": true

Change the font size

"editor.fontSize": 18

Change the zoom level

"window.zoomLevel": 5

Font ligatures

"editor.fontLigatures": true

Tip: You will need to have a font installed that supports font ligatures. FiraCode is a popular font on the VS Code team.

Auto Save

"files.autoSave": true

Format on save

"editor.formatOnSave": true,

Change the size of tab characters

"editor.tabSize": 4

Spaces or tabs

"editor.insertSpaces": true

Render whitespace

"editor.renderWhitespace": true

Ignore files / folders

Removes these files / folders from your editor window.

"files.exclude": {
		"somefolder/": true, 
		"somefile": true
}

Remove these files / folders from search results.

"search.exclude": {
    "someFolder/": true,
    "somefile": true
}

And many, many others.

Language specific settings

For those settings you only want for specific languages.

"[languageid]": {
    
}

Tip: You can find the language ID by typing in the command palatte "Configure language specific settings"

Add JSON Validation

Enabled by default for many files. Create your own schema and validation in settings.json

"json.schemas": [
    {
        "fileMatch": [
            "/bower.json"
        ],
        "url": "http://json.schemastore.org/bower"
    }
]

or for a schema defined in your workspace

"json.schemas": [
    {
        "fileMatch": [
            "/foo.json"
        ],
        "url": "./myschema.json"
    }
]

or a custom schema

"json.schemas": [
    {
        "fileMatch": [
            "/.myconfig"
        ],
        "schema": {
            "type": "object",
            "properties": {
                "name" : {
                    "type": "string",
                    "description": "The name of the entry"
                }
            }
        }
    },

See more in the documentation.

Git Integration

Diffs

Click Git icon then select the file to diff.

Side by side

Default is side by side diff.

Inline view

Toggle inline view by clicking more button in the top right.

Branches

Easily switch between branches via the status bar.

Staging

Stage all

Hover over the number of files and click the plus button.

Stage selected

Stage a portion of a file by selecting that file (using the arrows) and then choosing "Stage Selected Ranges" from the command palette.

Undo last commit

See Git output

Sometimes I want to see what my tool is doing. Visual Studio Code makes it easy to see what git commands are running. This is helpful when learning git or debugging a difficult source control issue.

Mac: shift+cmd+u

Windows / Linux: ctrl+shift+u

to run toggleOutput. Select Git in the dropdown.

Gutter indicators

View diff decorations in editor. See documentation for more details.

Resolve merge conflicts

During a merge click the git icon and make changes in the diff view.

Setup VS Code as default merge tool

git config --global merge.tool code

Debugging

Configure debugger

f1 and select "Debug: Open Launch.json", select the environment. This will generate a launch.json file. Works out of the box as expected for Node and other environments. May need some additional configuration for other languages. See documentation for more details.

Breakpoints and stepping through

Place breakpoints next to the line number. Navigate forward with the debug widget.

Data inspection

Inspect variables in the debug panels and in the console.

Task Runner

Auto detect tasks

f1, type "Configure Task", then select "Configure Task Runner". This will generate a task.json file with content like the following. See documentation for more details.

{
	// See http://go.microsoft.com/fwlink/?LinkId=733558
	// for the documentation about the tasks.json format
	"version": "0.1.0",
	"command": "npm",
	"isShellCommand": true,
	"showOutput": "always",
	"suppressTaskName": true,
	"tasks": [
		{
			"taskName": "install",
			"args": ["install"]
		},
		{
			"taskName": "build",
			"args": ["run", "build"]
		}
	]
}

There are occasionally issues with auto generation. Check out the documentation for getting things to work properly.

Run tasks from command palette

f1, run the command "Run Task", and select the task you want to run. Terminate the running task by running the command "Terminate Running Task"
