@saadeh/ext-sync

🔄 A simple CLI tool for syncing and sharing VS Code/Cursor/Antigravity extensions across teams and projects.

🚀 Why ext-sync?

Ever joined a new project and spent hours installing the "right" extensions? Or wanted your entire team to use the same development setup? ext-sync solves this by letting you:

• 📦 Import your current extensions into a shareable config file
• 🔄 Sync extensions from a config file (perfect for onboarding)
• 🎯 Initialize projects with stack-specific extensions (React, Laravel, NestJS, JavaScript)
• ⚡ Smart filtering - only installs extensions you don't already have

📥 Installation

npm install -g @saadeh/ext-sync

📁 Configuration File

The ext-sync.json file is dead simple. It just contains a list of your extensions:

{
  "extensions": [
    "esbenp.prettier-vscode",
    "dbaeumer.vscode-eslint",
    "eamodio.gitlens"
  ]
}

1. Initialize new setup

If you are starting fresh, use the interactive menu to install recommended extensions for your stack (e.g., React, Laravel, Python).

ext-sync
# Select "Initialize new setup"

• 📦 Installs recommended extensions for your chosen stack.
• 💾 Creates ext-sync.json with these extensions.
• ➕ Appends to the list if you run it again for another stack.

2. Import existing extensions

If you already have a perfect setup, save it!

ext-sync
# Select "Import extensions"

• 📥 Reads all your currently installed extensions.
• 💾 Saves them to ext-sync.json.
• 🔄 Merges with existing list if the file already exists.

3. Sync extensions

Install everything in your config to your current editor.

ext-sync
# Select "Sync extensions"

• 🚀 Installs all extensions listed in ext-sync.json.
• ⚡ Efficient: Only installs what is missing.
• 🕵️ Smart: Automatically detects if you are using VS Code, Cursor, or Antigravity.

The ext-sync.json file supports multiple stacks:

{
  "editor": "antigravity",
  "stacks": ["react", "laravel"],
  "extensions": {
    "react": [
      "dsznajder.es7-react-js-snippets",
      "esbenp.prettier-vscode",
      "dbaeumer.vscode-eslint"
    ],
    "laravel": [
      "bmewburn.vscode-intelephense-client",
      "onecentlin.laravel-blade"
    ]
  }
}

Commit this file to your repo so your team can sync instantly!
