name	vscode-settings
description	VS Code configuration, extensions, keybindings, and workspace optimization. Use when user mentions "vscode", "vs code", "vscode settings", "vscode extensions", "keybindings", "code editor", "workspace settings", "settings.json", "launch.json", "tasks.json", "vscode snippets", "devcontainer", "remote development", or customizing their VS Code setup.

VS Code Settings

Settings Hierarchy

Settings resolve in this order (later overrides earlier):

1. Default settings - built-in VS Code defaults
2. User settings - ~/.config/Code/User/settings.json (Linux), ~/Library/Application Support/Code/User/settings.json (macOS), %APPDATA%\Code\User\settings.json (Windows)
3. Workspace settings - .vscode/settings.json in workspace root
4. Folder settings - per-folder overrides in multi-root workspaces

Commit .vscode/settings.json, extensions.json, tasks.json, and launch.json to version control. Add user-specific paths to .gitignore if needed.

Keybinding Customization

Keybindings live in keybindings.json. Open with Cmd+K Cmd+S (macOS) or Ctrl+K Ctrl+S (Windows/Linux).

Structure

[
  {
    "key": "ctrl+shift+d",
    "command": "editor.action.duplicateSelection"
  },
  {
    "key": "ctrl+shift+k",
    "command": "editor.action.deleteLines",
    "when": "editorTextFocus && !editorReadonly"
  }
]

When Clauses

Common context keys for conditional bindings:

• editorTextFocus - cursor is in an editor
• editorHasSelection - text is selected
• editorLangId == 'typescript' - specific language
• resourceExtname == '.json' - specific file extension
• inDebugMode - debugger is active
• sideBarVisible - sidebar is open
• terminalFocus - terminal has focus

Combine with &&, ||, !:

{
  "key": "ctrl+enter",
  "command": "workbench.action.terminal.sendSequence",
  "args": { "text": "\n" },
  "when": "terminalFocus && !terminalTextSelected"
}

Key Chords

Two-part shortcuts:

{
  "key": "ctrl+k ctrl+c",
  "command": "editor.action.addCommentLine"
}

  "label": "custom-build",
  "type": "shell",
  "command": "make build",
  "problemMatcher": {
    "owner": "custom",
    "fileLocation": ["relative", "${workspaceFolder}"],

    }
  }
}

Compound Tasks

  "program": "${file}",
  "console": "integratedTerminal",
  "justMyCode": true,
  "env": { "PYTHONDONTWRITEBYTECODE": "1" }
}

Go

Multi-Root Workspaces

Create a .code-workspace file:

  "folders": [
    { "name": "Frontend", "path": "./packages/frontend" },
    { "name": "Backend", "path": "./packages/backend" },
    { "name": "Shared", "path": "./packages/shared" }
  ],
  "settings": {
    "files.exclude": { "**/node_modules": true }
  },
  "extensions": {
    "recommendations": ["dbaeumer.vscode-eslint"]
  }
}

Per-folder settings override workspace settings. Open with code project.code-workspace.

Dev Containers

devcontainer.json

// .devcontainer/devcontainer.json
{
  "name": "Node.js Dev",
  "image": "mcr.microsoft.com/devcontainers/typescript-node:20",
  "features": {
    "ghcr.io/devcontainers/features/docker-in-docker:2": {},
    "ghcr.io/devcontainers/features/github-cli:1": {}
  },
  "forwardPorts": [3000, 5432],
  "postCreateCommand": "npm install",
  "customizations": {
    "vscode": {
      "extensions": [
        "dbaeumer.vscode-eslint",
        "esbenp.prettier-vscode"
      ],
      "settings": {
        "editor.formatOnSave" 
      
    
  

With Dockerfile

{
  "name": "Custom Dev",
  "build": {
    "dockerfile": "Dockerfile",
    "context": "..",
    "args": { "NODE_VERSION": "20" }
  },
  "remoteUser": "node",
  "mounts": [
    "source=${localEnv:HOME}/.ssh,target=/home/node/.ssh,type=bind,readonly"
  ]
}

Docker Compose

{
  "name": "Full Stack",
  "dockerComposeFile": "docker-compose.yml",
  "service": "app",
  "workspaceFolder": "/workspace",
  "shutdownAction": "stopCompose"
}

Remote Development

SSH: Install "Remote - SSH" extension. Configure ~/.ssh/config, then Cmd+Shift+P > "Remote-SSH: Connect to Host". VS Code installs its server on the remote automatically.

WSL: Install "WSL" extension. Run code . from a WSL terminal, or use Cmd+Shift+P > "WSL: Connect to WSL".

Tunnels: Run code tunnel on a remote machine to create a persistent tunnel. Connect from any browser at vscode.dev or from the desktop app via "Remote - Tunnels" extension. No SSH required.

Extension Authoring Basics

Scaffold a new extension:

npm install -g yo generator-code
yo code

Minimal package.json contribution points:

{
  "contributes": {
    "commands": [{
      "command": "myext.helloWorld",
      "title": "Hello World"
    }],
    "keybindings": [{
      "command": "myext.helloWorld",
      "key": "ctrl+shift+h"
    }],
    "configuration": {
      "title": "My Extension",
      "properties": {
        "myext.enable": { "type": "boolean", "default": true }
      }
    }
  }

Register in src/extension.ts:

import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {
  const disposable = vscode.commands.registerCommand('myext.helloWorld', () => {
    vscode.window.showInformationMessage('Hello World!');
  });
  context.subscriptions.push(disposable);
}

export function deactivate() {}

Debug with F5 (launches Extension Development Host). Publish with vsce publish.

Profiles

Create profiles for different workflows: Cmd+Shift+P > "Profiles: Create Profile".

Use cases:

• Frontend - Tailwind, ESLint, Prettier, browser debug configs
• Python - Pylance, Ruff, Jupyter, Python debug configs
• Writing - Markdown extensions, zen mode defaults, spell checker
• Minimal - No extensions, clean UI for demos/screencasts

Export/import profiles as .code-profile files or share via GitHub Gist.

Switch profiles via the gear icon in the bottom-left or Cmd+Shift+P > "Profiles: Switch Profile".

Settings Sync

Enable via Cmd+Shift+P > "Settings Sync: Turn On". Syncs:

• Settings, keybindings, snippets, extensions, UI state, profiles

Sign in with GitHub or Microsoft account. Choose what to sync in Settings Sync preferences.

For teams, commit .vscode/settings.json and .vscode/extensions.json instead of relying on sync. Keep personal preferences (theme, font size) in user settings only.

Productivity Tips

Multi-cursor: Alt+Click to add cursors. Cmd+D to select next occurrence. Cmd+Shift+L to select all occurrences. Cmd+Alt+Up/Down to add cursors above/below.

Emmet: Type abbreviations and press Tab in HTML/JSX. div.container>ul>li*3 expands to full markup. Works in JSX with "emmet.includeLanguages": { "javascriptreact": "html" }.

Breadcrumbs: Enable with "breadcrumbs.enabled": true. Navigate file path and symbol hierarchy at the top of the editor.

Zen Mode: Cmd+K Z to enter. Hides all UI chrome for focused editing. Configure with "zenMode.hideLineNumbers", "zenMode.centerLayout".

Quick Open: Cmd+P to open files by name. Add : for go-to-line, @ for go-to-symbol, # for workspace symbol search.

Command Palette: Cmd+Shift+P for all commands. Type partial matches.

Side-by-side editing: Cmd+\ to split. Drag tabs between groups. Cmd+1/2/3 to focus groups.

Timeline view: Built-in local file history in the Explorer sidebar. Compare previous versions without Git.

Sticky scroll: Shows nested scope context at the top of the editor. Enable with "editor.stickyScroll.enabled": true.

Project-Specific Formatter/Linter Configuration

Per-Language Formatters

// .vscode/settings.json
{
  "[typescript]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode",
    "editor.tabSize": 2
  },
  "[python]": {
    "editor.defaultFormatter": "charliermarsh.ruff",
    "editor.tabSize": 4,
    "editor.formatOnSave": true
  },
  "[go]": {
    "editor.defaultFormatter": "golang.go",
    "editor.formatOnSave": true,
    "editor.codeActionsOnSave": {
      "source.organizeImports": "explicit"
    }
  },
  "[json]": {
    "editor.defaultFormatter" 
  
   
     
     
     
  

ESLint + Prettier Coexistence

{
  "eslint.validate": ["javascript", "typescript", "javascriptreact", "typescriptreact"],
  "prettier.requireConfig": true,
  "editor.formatOnSave": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": "explicit"
  }
}

Order matters: Prettier formats first (on save), then ESLint fixes remaining issues (code action on save). Use eslint-config-prettier to disable ESLint rules that conflict with Prettier.

Ruff for Python

{
  "[python]": {
    "editor.defaultFormatter": "charliermarsh.ruff",
    "editor.codeActionsOnSave": {
      "source.fixAll.ruff": "explicit",
      "source.organizeImports.ruff": "explicit"
    }
  }
}
