Why?

Steam hosts all of the CS:GO resource images on their CDN, but unfortunately finding the URL for them was difficult in the past and would require scraping the market or inventories.

This library allows you to retrieve the needed CDN URLs given the sticker name, which can save you lots in bandwidth and prevents you from having to scrape it or host it yourself.

How?

Most of the graphical resources for CSGO are stored in VPK files which include the sticker, music kit, tools, and status icon images.

The root of a VPK contains a dir file (pak01_dir.vpk) that specifies where files are located over multiple packages. If you look in the install directory of CS:GO, you'll see pak01_003.vpk, pak01_004.vpk, etc... where these files are located.

Thankfully, Valve was kind enough (as of writing this) to include all of the relevant images in a packages which are only ~13GB.

This library, using DepotDownloader, gets all require VPK files from the public branch of CS2. It will only download the VPK files that have changed since the last update, and will only download the relevant VPK files for the options you have enabled.

It then Extracts the real images from the VPK files and stores them in a data directory via the command line interface of Source 2 Viewer.

When trying to retrieve a CDN image URL for a given item, the library takes the SHA1 hash of the image and the VPK path that links to it to generate the corresponding URL.

Example URL: https://steamcdn-a.akamaihd.net/apps/730/icons/econ/stickers/cologne2015/mousesports.3e75da497d9f75fa56f463c22db25f29992561ce.png

How to Install

npm install csgo-cdn

See example.js

import SteamUser from 'steam-user';
import CSGOCdn from './index.js';

const user = new SteamUser();
const cdn = new CSGOCdn(
    user,
    {
        logLevel: 'debug'
    }
);

cdn.on('ready', () => {
   console.log(cdn.getItemNameURL('M4A4 | 龍王 (Dragon King) (Field-Tested)'));
   console.log(cdn.getItemNameURL('★ Karambit | Gamma Doppler (Factory New)', cdn.phase.emerald));
});

  }

getItemNameURL(marketHashName, phase)

• marketHashName - The market hash name of an item (ex. "Sticker | Robo" or "AWP | Redline (Field-Tested)")
• phase - Optional weapon phase for doppler skins from the phase enum property

Note: If the item is a weapon, you can omit the wear (ex. AWP | Redline)
