steam-tradeoffers is a library for Node.js written in JavaScript. It allows you to automate Steam trading using trade offers. It was designed with node-steam in mind, but does not depend on it directly. Some of the methods of the library are wrappers for Steam Web API.
Please read the FAQ first if you have any questions.
If your question is not answered here, please ask it in https://github.com/steam-forward/node-steam-forum, please do not open an issue here. Issues are only for bugs and feature requests.
npm install steam-tradeoffers
Instantiate a SteamTradeOffers object...
var SteamTradeOffers = require('steam-tradeoffers');
var offers = new SteamTradeOffers();...then setup session and WebAPI key:
offers.setup({
sessionID: sessionID,
webCookie: cookies,
APIKey: webAPIKey
});You can obtain session information with node-steam and its plugin steam-weblogon.
A demo bot exists that also serves as a donation bot.
Source code (based on the storehouse.js example).
You'll need to install node-steam, steam-weblogon, and steam-web-api-key in order to run the examples.
The storehouse.js file contains an example of handling incoming trade offers.
The offerbot.js is an example of making a trade offer.
On first launch both of the examples will 'crash'. Check your email for Steam Guard code and edit an example file to add it, then run it again.
Please read the FAQ before creating an issue about examples.
options param of all methods is just an object. All callbacks supplied with Error as the first argument or null if no errors occured.
