Retrieves the Steam CDN URLs for CS:GO Item Images from their market_hash_name or properties.

Can retrieve CDN images for:

• Stickers
• Characters
• Graffiti (without tint)
• Weapons (and doppler phases)
• Music Kits
• Tools (Crate Keys, Cases, Stattrak Swap Tool, etc...)
• Status Icons (Pins, ESports Trophies, Map Contribution Tokens, Service Medals, etc...)

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.

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 few packages which are only ~400MB.

This library, using node-steam-user, checks the manifest for any updates to the public branch of CS:GO, and if so, downloads only the required VPK packages that contain all relevant images if they have changed from the content servers.

When trying to retrieve a CDN image URL for a given item, the library takes the SHA1 hash of the file 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

const SteamUser = require('steam-user');
const csgoCDN = require('csgo-cdn');

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));
});

• 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)

Ensure that you have enabled the relevant VPK downloading for the item category by using the options in the constructor.

Returns the 'large' version of the image.

• stickerName - Name of the sticker path from items_game.txt (ex. cluj2015/sig_olofmeister_gold)
• large - Whether to obtain the large version of the image

• stickerName - Name of the patch path from items_game.txt (ex. case01/patch_phoenix)
• large - Whether to obtain the large version of the image

• defindex - Definition index of the item (ex. 7 for AK-47)
• paintindex - Paint index of the item (ex. 490 for Frontside Misty)
