npm install steam-js-api
A simple and clean API wrapper for the Steamworks Web API, specializing in providing great documentation and straight-forward results. The Steamworks Web API is very inconsistent, this wrapper fixes that by normalizing parameters and responses into predictable, more usable formats.
The project includes the most important parts from the Steamworks Web API, and is still growing. The full public Steamworks Web API will be added in future releases. Plans for implementing a full trading and inventory system are also on the horizon.
This is packaged with NPM, so you can just do npm install steam-js-api and get going with it.
const api = require('steam-js-api')You can also just download one of the releases, and load the file in your javascript like this:
const api = require('./steam-js-api/app.js')The official documentation can be found in the Github Wiki. Everything is listed by the Web API interface that it uses, along with a short description of what information you can get from it. Everything is perfectly organized, as all things should be.
Counter-Strike: Global Offensive (CSGO) has a special stat format, making use of a scheme defined in json/stats.json. For information about this, see the Stats-CSGO wiki page.
You can use every function like a Promise or with a callback. If no callback is given, then the function returns a Promise. Anytime a Steam ID is used, the module internally verifies the ID before making the request, and will return an error if the Steam ID isn't valid.
Almost every function requires you to set the API key. You only have to set this once by calling setKey(). Because almost all functions need an API key, the ones that do not will explicitly say so in the wiki. An exception will be thrown if you don't set an API key before calling a function that requires one.
// Basic usage example, with API key
const api = require('steam-js-api')
// I recommend using environment variables for security. This is what I do.
// More info here: https://www.twilio.com/blog/working-with-environment-variables-in-node-js-html
api.setKey('{YOUR_KEY_HERE}')
steamID = '76561198099490962' // My Steam ID, feel free to use it for testing :)
appID = 730 // We only want to check for one game
moreInfo = true // Provide more info (name, links)
// Synchronous result
let result
try {
result = await api.getOwnedGames(steamID, appID, moreInfo)
console.log(result.data.games[0])
} catch (e) {
console.error(e)
}
// With a callback
api.getOwnedGames(steamID, appID, moreInfo, (result) => {
if (result.error)
console.error(result)
else
console.log(result.data.games[0])
})
// Alternatively, use a Promise
api.getOwnedGames(steamID, appID, moreInfo).then(result => {
console.log(result.data.games[0])
}).catch(console.error)This will print out an object that looks like this one:
{
"name": "Counter-Strike: Global Offensive",
"appid": 730,
"playtime": 61041,
"playtime_recent": 1,
"url_store": "https://store.steampowered.com/app/730",
"url_store_header": "https://steamcdn-a.akamaihd.net/steam/apps/730/header.jpg",
"url_app_logo": "https://steamcdn-a.akamaihd.net/steamcommunity/public/images/apps/730/d0595ff02f5c79fd19b06f4d6165c3fda2372820.jpg",
"url_app_icon": "https://steamcdn-a.akamaihd.net/steamcommunity/public/images/apps/730/69f7ebe2735c366c65c0b33dae00e12dc40edbe4.jpg"
}To keep the library small, I wrote my own testing code that works very well and is pretty simple. Every function is tested in this file: tests/main.js. The format is pretty straight-forward, and nicely demonstrates every function in real use. However, the wiki is still the best place to actually learn how to use the functions!
The next section is the full list of all interfaces this wrapper supports. If you can't find one that you want, please follow this example to get the plain JSON object until the interface is officially supported.
api.request('ISteamNews/GetNewsForApp/v2', {appid: '730'}, res => {
if (res.error) {
console.error(res.error)
console.error(`Data: ${res.data}`)
return
}
items = res.data.newsitems
})All supported interfaces are listed here. If you can't find one that you want, please use the above example to get the basic JSON response until the interface is officially supported. Almost all supported interfaces have unique object structures to allow easier access to data. You can find out the exact structure by copying the examples and running them, or by checking the wiki.
Trading specific interface.
Specifically playtime, owned games, badges, and Steam level.
Steam economy item related stuff.
Returns more detailed information about user profiles; summaries, bans, friends.
Game statistics related APIs; achievements, scores, stats, etc.
- GetGlobalAchievementPercentagesForApp
- GetNumberOfCurrentPlayers
- GetPlayerAchievements
- GetSchemaForGame
- GetUserStatsForGame
These are custom functions that don't use the traditional Steam Web API stuff. As such, they might change in functionality at some point in the future. But I doubt it, Volvo has barely touched the Web API for a number of years now, so this stuff should work as long as everything else in this list does.
Counter-Strike: Global Offensive specific functions, all in a CSGO object as part of the module. This also includes wrappers for functions from ISteamUserStats and ISteamEconomy to allow for more readable code. See the CSGO wiki page for more information about this submodule.
If there's something you can't find, then it likely isn't officially supported yet. But I have the solution! Just follow this simple example and you can still quickly access the interface.
api.request('ISteamNews/GetNewsForApp/v2', {appid: '730'}, res => { if (res.error) { console.error(res.error) console.error(`Data: ${res.data}`) return } items = res.data.newsitems })
The main goal of the project is to improve the existing Steamworks Web API, essentially by reformatting it and making it easier to work with. The existing documentation is lacking in many areas, and this project aims to fix it.
Another big goal is to keep everything simple and focused into one library; avoiding dependencies. In sacrificing some initial development time, the library is much smaller and easier to build upon.
For the real attentive people, this repository has some scripts I wrote myself to streamline some development tasks. Obviously, these aren't included in the installed NPM package. Feel free to use them if you want, they come under the exact same license as everything else.
Please do not request interfaces to be added. I'm going through the entire list of interfaces and adding them one-by-one. While you wait, check out the above example code for accessing unsupported interfaces.
