node-steam-inventory

A module for interacting with steam for getting users inventory

Two endpoints

Steam has two endpoints:

• https://steamcommunity.com/profiles/STEAM_ID/inventory/json/APP_ID/CONTEXT_Id/ (OLD)
• https://steamcommunity.com/inventory/STEAM_ID/APP_ID/CONTEXT_Id/ (NEW)

You can see their differences in stackoverflow. In this module you can use both of them.

Installation

npm install @xfaider/node-steam-inventory

Usage

var steamInventoryModule = require('@xfaider/node-steam-inventory');
var steamInventory = new steamInventoryModule.SteamUserInventory(options);

Constructor params

Params:

• options[defaultGotOptions]: default options for got module for all call methods. Default: {}.

Basic usage

steamInventory.loadAndFormat({
    steamId: userSteamId
}).then(formattedArray => {
    console.log(formattedArray);
    // Array of objects formatted by `formatItem`
});
