Wax-expresstrade NPM

WAX ExpressTrade API for Node.js

license

Powerful async/await based Node.js implementation of OPSkins WAX ExpressTrade.

Stop wasting time on coding endpoint communication, event polling and bothering with two factor authentication - just pass your api key with secret and use methods out-of-the-box.

INFO FOR v.1.1: API has changed a lot from now - please update your code before updating wax-expresstrade library to the newest version.

Installation

npm i wax-expresstrade --save

Powerful!

:arrows_counterclockwise: We base on official implementation - it means, that interfaces, methods and responses are identically named as in documentation. E.g. IUser/GetInventory refers to API.IUser.GetInventory() method.

:rocket: The entire module is async/await friendly - so you do not need to worry about promisifying or callback hell.

:sparkles: All trade-offers updates are emitted as event, which makes catching changes unbelievably easy! E.g. API.on('OfferChanged', offer => console.log(offer))

:fire: Two-Factor authentication? Naah! wax-expresstrade handles all this stuff with no additional configuration, just pass twoFactorSecret and... that's all!

Usage

const ExpressTrade = require('wax-expresstrade')

// First, initialize our module
const API = new ExpressTrade({
  apiKey: 'OPSkins API Key goes here',
  twoFactorSecret: 'Secret from opskins mobile auth goes here',
  pollInterval: 5000 // Optional, but just set this one value and module will handle all offers updates automatically!
})

// It's ready to use, wasn't it simple?
const appId = 1 // VGO

const mySkins = await API.IUser.GetInventory({ appId })
const anotherOneSkins = await API.ITrade.GetUserInventory({ uid: 72789, appId })

console.log(
  `You have ${mySkins.items.length} skins and your friend has got ${
    anotherOneSkins.items.length
  } ones!`
)

Methods

Basically, there is no need to re-define available methods. Take a look into documentation, look for module (e.g. IItem) and method (e.g. GetItems)

Execute node code with const items = await API.IItem.GetItems({ skuFilter: [10, 20, 25, 40] })

Events

IMPORTANT: You need to set pollInterval value in milliseconds (min. 1000) to make module emit events!

Intercepting events is really easy, take a look:

const API = ... // ExpressTrade initialization is described above in "Usage" section

API.on('OfferChanged', offer => {
	console.log(`Offer #${offer.id} changed its state to ${offer.state}!`)
	console.log(`That offer was sent by ${offer.sent_by_you ? 'you' : 'someone else'}`)
})

OfferChanged

offer - Trade Offer Object

Emitted alongside with state-changed events of offers, which have been already created (e.g. OfferAccepted, OfferDeclined, but not OfferSent/OfferReceived).
