Steam WebAPI Client

This is yet another node.js module for the Steam WebAPI. I made it for myself because I'm sure none of the other modules are any good, but anyone is of course welcome to use it. Don't expect too many updates outside of fixing stuff.

It detects and handles errors from the X-eresult and X-error_message headers. It also requests gzip compression for responses.

Constructor

The constructor takes two arguments: key and localAddress.

var SteamWebAPI = require('@doctormckay/steam-webapi');
var api = new SteamWebAPI("yourapikey", "192.168.0.5");

The first argument is your API key. The second is the local IP address you want to make your requests from. Both are optional. If you don't provide an API key you can only use the methods that don't require one.

You can change your API key at any time by assigning it to the key property. Same goes for localAddress with the localAddress property.

Methods

get(iface, method, version[, input], callback)

• iface - The WebAPI interface that you want to use. The leading "I" is optional.
  • For example, IGameServersService or SteamUser.
• method - The WebAPI method that you want to use.
  • For example, GetPlayerSummaries.
• version - The numeric version of the method you want to use.
  • For example, 1.
• input - Optional. An object containing the parameters you want to pass to this request.
  • You shouldn't provide key or format, as these will be filled automatically.
  • Array inputs (e.g. input[0]=foo&input[1]=bar) should be passed as JavaScript arrays. They will be serialized accordingly.
• callback - A function to be called when the request completes
  • err - An Error object on failure, or null on success
  • response - An object containing the response data

Performs a GET request to a method.

post(iface, method, version[, input], callback)

Same as get except with a POST request.

Failure

On failure, you'll get back an Error object with the following properties:

• statusCode - The HTTP status code of the response. This may be 200 if an error was detected elsewhere.
• eresult - Only if Steam sends back an X-eresult header, this will be an EResult value.
• message - A string describing the error that occurred. These are the conditions that are checked, in order from top to bottom:
  • If X-eresult is returned, is not 1, and X-error_message is returned, then this is the value of X-error_message; otherwise,
  • If X-eresult is returned and is not 1, then this is the string name of the EResult value (for example, NoMatch); otherwise,
  • If the HTTP status code is not 200, this is the HTTP status message (for example, Not Found or Unauthorized); otherwise,
  • If the received response wasn't valid JSON, then this is Malformed response

Response

Response data is parsed as JSON. If the top-level object contains exactly one property named response, then the value of the response property is returned. Otherwise, the parsed JSON is returned as-is.
