Steam Web API Library

Version

Steam Web API Library is currently in version 1.0.2 per the Semantic Versioning standards.

Enhancements, features, and known issues are available in the Issues and Projects section of this respository.

Overview

Steam Web API Library is a JavaScript library that makes it easier to query data from the Steam Web API. The library reduces the amount of tedious API endpoint information you need to look up by doing that part for you. All you need to do is import the library and follow the usage guide below! The library can return data as a JSON, XML, or VDF (Valve Data Format) object.

1.0 | Quickstart Guide

Steam Web API Library is easy to install and use:

Run npm i swalib in your project root directory.
Ensure that you have your Steam Web API key in a .env file in the root directory of your project. Refer to example.env for naming requirements:

STEAM_KEY=XXXXXXXXXXXXXXXXXXXXXXX

Note: a future update will allow you to specify where your .env file is located. For the time being, it must be in the root directory of your project.

Import Steam Web API Library into your project:

import CallSteamAPI from "./SteamWebAPILibrary.js";

2.0 | Usage and Functionality

NOTE: Methods that request information from specific Steam users require that the user profiles be set to "public" visibility. Otherwise the server will return an undefined object.

2.1 | Option one (recommended) -- passing arguments as a destructured object in the async function.

Create an async function and call the library method you wish to use, then call the function as needed in your synchronous code.

import CallSteamAPI from "./src/SteamWebAPILibrary.js";

const myAppVariable = new CallSteamAPI();

async function myFunc() {
  const result = await myAppVariable.getNewsForApp({
    appid: "440",
    count: "4",
    format: "json",
    maxlength: "500",
  });

  return result;
}

myFunc();

Parameters that have a default value will maintain their default value whether or not they are included in your destructured object.

2.2 | Option two -- passing arguments in your function call directly.

Create an async function and call the library method you wish to use, then call the function as needed in your synchronous code. Arguments passed must match parameter order.

import CallSteamAPI from "./src/SteamWebAPILibrary.js";

const myAppVariable = new CallSteamAPI();

async function myFunc(appid, count, maxlength, format) {
  const result = await myAppVariable.getNewsForApp({
    appid,
    count,
    maxlength,
    format,
  });

  return result;
}

myFunc("440", "5", "500", "json");

2.3 | Querying for specific data endpoints

Steam Web API Library is capable of flexibly returning specific fields as well as returning the whole data object. By default, the full data object will be returned.

Specific data endpoint querying is only supported in JSON format. XML and VDF objects are returned as-in in their full scope and format.

The special specificData parameter determines whether the library will attempt to pull specific data information from the API. If specificData is specified with a valid endpoint, the library will return only that data:

import CallSteamAPI from "./src/SteamWebAPILibrary.js";

const myAppVariable = new CallSteamAPI();

async function myFunc() {
  const result = await myAppVariable.getPlayerAchievements({
    appid: "440",
    steamid: "01234567890123456",
    specificData: "gameName", //Returns only the "gameName" field for the specified user and app
  });

  return result;
}

6.0 | Tests

Description: In order to scalable and maintainable code, this package has a suite of tests. This section discusses what those tests do, and how to run them.

Summary: This package has an in-memory cache. Since it currently supports GET requests, it doesn't not invalidate this cache, and since it's in-memory it doesn't need to support expiration.

The tests located in /tests currently test the in-memory cache, which can also be switched off by explicitely passing in a false value for useCache.

When running these tests, the CallSteamAPI class bypasses the check for a Steam API Key.
