NodeJS Script for downloading Visual Studio Code extensions.

Use Cases

• Downloads the extensions as .vsix files
• Allow an offline VSCode instance to install extensions offline
• Download the extensions for an arbitrary target platform

Limitations:

• Only the latest extension version can be downloaded
• The latest version might be a pre-release version
• Requires to download a Chromium browser binary

How it works

This script uses a headless Chromium browser & NodeJS to download the extensions. A .txt newline-delimited list of extension ids must be supplied.

How to use

Installation

1. Download & Install NodeJS. Version 16 or above is good.
2. Git Clone the repository, or download a .zip package from the Releases page.
3. Enter the repository which you'd cloned/unzipped, and install this project's NPM packages via npm install.

Configuration

Prepare a newline-limited file of extension ids. If VSCode is in your $PATH you can run the following command to export a list of extensions:

$ code --list-extensions > extensions.txt

The following command runs the script and downloads it to the ~/Downloads/vscode-ext/'s directory:

$ node src/index.js -i extensions.txt

The following options are available:

Required:
  -i, --input  A newline-delimited list of extension ids to download. You can run VSCode CLI to generate this: `code --list-extensions > extensions.txt                                        [string] [required]
