Automatically install extensions in VS Code?

Thanks to Daniel's suggestion, and I find if you want to keep a list of vscode extensions and install all of them in single click, you can try this approach:

1. Create the list of extensions you want using the workspace recommended extensions

• Use the Configure Recommended Extensions command to create the extensions.json file You will create a file like this:

{
  // See https://go.microsoft.com/fwlink/?LinkId=827846 to learn about workspace recommendations.
  // Extension identifier format: ${publisher}.${name}. Example: vscode.csharp
  // List of extensions which should be recommended for users of this workspace.
  "recommendations": [
    "ms-vscode.cpptools",
    "file-icons.file-icons",
    "shd101wyy.markdown-preview-enhanced",
    "sagebind.mathpad",
    "johnpapa.vscode-peacock"
  ],
  // List of extensions recommended by VS Code that should not be recommended for users of this workspace.
  "unwantedRecommendations": []
}

• Add your favorite vscode extension id into the list in JSON

2. Re-launch vscode to open the workspace folder (the parent folder for .vscode folder)
3. Navigate to "Extensions", filter extensions using "Recommended" filter
4. A list of extensions will be shown in "Workspace Recommendations"
5. Click the ☁️ button to install all extensions at once

See https://code.visualstudio.com/docs/editor/extension-gallery#_command-line-extension-management

I wrote this Makefile to automatically install extensions

freeze-extensions:
    code --list-extensions > extensions.txt

install-extensions:
    cat extensions.txt | xargs -L 1 code --install-extension
