A Node.js script that extracts Steam Workshop addon IDs from a Steam collection and outputs them in a format that can be used for Garry's Mod servers.

The script:

1. Connects to the Steam API
2. Downloads the details of a Steam collection
3. Extracts all workshop IDs from the collection
4. Generates an addons.txt file with resource.AddWorkshop() commands

1. Make sure Node.js is installed
2. Install the dependencies:

npm install

1. Open script.js in a text editor
2. Replace "collection-id-here" with the actual Steam collection ID
3. Run the script:

node script.js

You can find the collection ID in the URL of a Steam collection:

https://steamcommunity.com/sharedfiles/filedetails/?id=123456789

In this example, 123456789 would be the collection ID.

The script creates an addons.txt file with the following format:

resource.AddWorkshop(106404821)
resource.AddWorkshop(110656185)
resource.AddWorkshop(118623480)
...

This file can be used directly in your Garry's Mod server.

• axios: For HTTP requests to the Steam API
• fs: Node.js built-in filesystem module

The script handles download errors and displays appropriate error messages.

After running the script with a valid collection ID, you'll get output like:

Ready! 492 Addons saved in addons.txt.

The generated addons.txt file contains all workshop IDs from the collection in the correct format for Garry's Mod.
