SteamUser

$3


SteamUser allows you to communicate with the Steam servers in the same manner as a proper Steam client. It's designed to
be a self-contained module which provides all the functionality expected of a Steam user client.

Upgrading from v3?

Installation

Install it from npm:

$ npm install steam-user

- Enums
- Static Methods
- Options
- Properties
- Methods
- Events

Some of the documentation for SteamUser, especially documentation for experimental features (but not exclusively),
is located in the GitHub wiki.

Patterns ^

There are a number of coding patterns that are repeated throughout SteamUser. **Please read this section in its
entirety before starting work with SteamUser.**

$3

All methods listed in this document that accept a callback also return a Promise. You may use either callbacks or
promises.

Legacy callbacks return their data spanning across multiple arguments. All promises (which return any data at all)
return a single object containing one or more properties. The names of these properties for legacy callbacks are the
names of the callback arguments listed in this readme. Newer callbacks return a single object response argument, which
is identical to the promise output for that method.

Some methods indicate that their callback is required or optional. **You are never required to use callbacks over
promises**, but if a callback is listed as optional then an unhandled promise rejection will not raise a warning/error.
If a callback is listed as required and you neither supply a callback nor handle the promise rejection, then a
promise rejection will raise a warning, and eventually a crash in a future Node.js release.

Enums ^

There are a lot of enums used in Steam. They're all available directly from SteamUser. For example, access EResult
using SteamUser.EResult.

All enums can be viewed on GitHub.

Additionally, for convenience, the name of an enum value is available from any enum at the key identified by the enum
value. For example, given an EResult of 88 you can translate it using SteamUser.EResult[88] which gives you
the string TwoFactorCodeMismatch.

Static Methods ^

Static methods, or functions attached directly to SteamUser, are called on the root module and not on instantiated handler instances.

$3

- amount - The amount of the currency
- currency - The currency code value in the ECurrencyCode enum

Formats a currency value and returns a string. For example:

``js
console.log(SteamUser.formatCurrency(12.34, SteamUser.ECurrencyCode.USD)); // $12.34
console.log(SteamUser.formatCurrency(12345, SteamUser.ECurrencyCode.JPY)); // � 12345
console.log(SteamUser.formatCurrency(123.45, SteamUser.ECurrencyCode.EUR)); // 123,45�
`

Options ^

There are a number of options which can control the behavior of the SteamUser object. They are:

$3

Controls where the Steam server list and sentry files are written. If null, no data will be automatically stored.

Defaults to a platform-specific user data directory.

- On OpenShift, this is $OPENSHIFT_DATA_DIR/node-steamuser
- On Windows, this is %localappdata%\doctormckay\node-steamuser
- On Mac, this is ~/Library/Application Support/node-steamuser
- On Linux, this is $XDG_DATA_HOME/node-steamuser, or ~/.local/share/node-steamuser if $XDG_DATA_HOME isn't defined or is empty

#### Custom Storage Engine

If you don't want to (or can't) save data to the disk, you can implement your own storage engine. To do this, simply add the following code:

`js
user.storage.on('save', function(filename, contents, callback) {
// filename is the name of the file, as a string
// contents is a Buffer containing the file's contents
// callback is a function which you MUST call on completion or error, with a single error argument

// For example:
someStorageSystem.saveFile(filename, contents, function(err) {
callback(err);
});
});

user.storage.on('read', function(filename, callback) {
// filename is the name of the file, as a string
// callback is a function which you MUST call on completion or error, with an error argument and a Buffer argument

// For example:
someStorageSystem.readFile(filename, function(err, file) {
if(err) {
callback(err);
return;
}

callback(null, file);
});
});
`

In this manner, you can save data to a database, a cloud service, or anything else you choose.

$3

A boolean which controls whether or not SteamUser will automatically reconnect to Steam if disconnected due to Steam going down.

Defaults to true.

$3

A boolean which controls whether or not SteamUser will use a single sentry file for all accounts.

If off, a file named sentry.accountname.bin will be saved for each account.
If on, a file named sentry.bin will be used for all accounts.

Defaults to false.

$3

What kind of machine ID will SteamUser send to Steam when logging on? Should be a value from EMachineIDType.

Added in 1.7.0.

Defaults to AccountNameGenerated.

$3

If you're using machineIdType AccountGenerated, this is the format it uses. This is an array of three strings, each of which will be hashed with SHA1 before being sent to Steam. {account_name} will be replaced with the current account name.

Added in 1.13.0.

Defaults to ["SteamUser Hash BB3 {account_name}", "SteamUser Hash FF2 {account_name}", "SteamUser Hash 3B3 {account_name}"].

$3

If enabled, then node-steam-user will internally cache data in memory about all apps and packages that it knows about.
Currently, node-steam-user "knows about" an app/package if:

- Packages
- You own it, or
- You request info about it via getProductInfo
- Apps
- It's in a known package, or
- You request info about it via getProductInfo, or
- A friend who is online plays the app, or
- You request info about an online user who is playing it via getPersonas

This option is required in order to use several methods and events. This works when logging in anonymously.

Added in 3.3.0.

Defaults to false.

$3

If picsCacheAll is enabled, enablePicsCache is enabled, and changelistUpdateInterval is nonzero, then apps and
packages which get updated while your bot is running will also be added to the cache. Default behavior is to only cache
apps and packages that are "known" via the above criteria.

Added in 3.3.0.

Defaults to false.

$3

If enablePicsCache is enabled, then node-steam-user will automatically request app/package changes (via
getProductChanges) for known apps and packages, and update the internal cache when they update. This is the frequency,
in milliseconds, for changelist update requests. Set to 0 to disable.

Added in 3.3.0.

Defaults to 60000. Minimum value 1000, although you're recommended to not go below 10 seconds or so.

$3

Set this to an object where keys are header names and values are header values, and those headers will be included
with all HTTP requests node-steam-user makes to the Steam WebAPI.

Added in 3.29.0.

Defaults to {}.

$3

Pass an IP here (as a string) to bind to that address, or null to let the OS decide.

Added in 4.0.0.

Defaults to null.

$3

Pass a port here to bind to that port, or null to let the OS decide.

Added in 4.0.0.

Defaults to null.

$3

Specify a URL here to use an HTTP proxy. For example, http://user:pass@1.2.3.4:8081

Added in 4.0.0.

$3

A value from EConnectionProtocol.

Added in 4.0.0.

Defaults to Auto.

$3

Set this to the full name of a language (e.g. "english" or "spanish") to localize specific things within steam-user.
Currently this is only used to localize rich_presence_string in user event data and in requestRichPresence.

Added in 4.0.0.

Defaults to english.

$3

If you're having trouble connecting to Steam (e.g. through a firewall or a proxy), set this to true. When in web
compatibility mode, connections to Steam will always use WebSockets (the protocol option will be ignored, and you
will get a warning if you set it to TCP), and only Steam servers listening on port 443 will be considered.

Added in 4.6.0.

Defaults to false.

Methods ^

$3


- options - An optional object containing zero or more options to set for this SteamUser.

Constructs a new SteamUser.

Prior to v4.0.0, it was possible to pass a SteamClient instance as the first argument to this constructor. This functionality was removed in v4.0.0. See the full list of v4 changes.

$3


- option - The name of the option to set
- value - The value to set for this option

Changes the value of an option.

$3

- options - An object containing zero or more options.

$3

- sentry - A Buffer containing the binary sentry file, binary SHA1 hash, or null to unset the set sentry

If you aren't using dataDirectory or you just want to provide your own sentry file, you can do it using this method.

You should call this before calling logOn. When you log on, SteamUser will use this sentry file.

You can provide either an entire sentryfile (preferred), or a Buffer containing the binary SHA1 hash of your sentryfile
(e.g. the output of the sentry event in node-steam 0.6.x).

$3


- details - An object containing details for this logon
- accountName - If logging into a user account, the account's name
- password - If logging into an account without a login key or a web logon token, the account's password
- loginKey - If logging into an account with a login key, this is the account's login key
- webLogonToken - If logging into an account with a client logon token obtained from the web, this is the token
- steamID - If logging into an account with a client logon token obtained from the web, this is your account's SteamID, as a string or a SteamID object
- authCode - If you have a Steam Guard email code, you can provide it here. You might not need to, see the steamGuard event. (Added in 1.9.0)
- twoFactorCode - If you have a Steam Guard mobile two-factor authentication code, you can provide it here. You might not need to, see the steamGuard event. (Added in 1.9.0)
- rememberPassword - true if you want to get a login key which can be used in lieu of a password for subsequent logins. false or omitted otherwise.
- logonID - A 32-bit integer to identify this login. The official Steam client derives this from your machine's private IP (it's the obfuscated_private_ip field in CMsgClientLogOn). If you try to logon twice to the same account from the same public IP with the same logonID, the first session will be kicked with reason SteamUser.EResult.LogonSessionReplaced. Defaults to 0 if not specified.
- As of v4.13.0, this can also be an IPv4 address as a string, in dotted-decimal notation (e.g. "192.168.1.5")
- machineName - A string containing the name of this machine that you want to report to Steam. This will be displayed on steamcommunity.com when you view your games list (when logged in).
- clientOS - A number to identify your client OS. Auto-detected if you don't provide one.
- dontRememberMachine - If you're providing an authCode but you don't want Steam to remember this sentryfile, pass true here.

v3.11.0 or later is required to use machineName or dontRememberMachine.
v4.3.0 or later is required to use webLogonToken.

Logs onto Steam. Omit the details object if you wish to login to an anonymous user account.

There are four ways to log onto Steam:

- Anonymously
- Omit accountName (or the details object entirely) and you will log onto an anonymous user account.
- Individually using account name and password
- These properties are required:
- accountName

- authCode - Specify if you are using an email Steam Guard code.
- twoFactorCode - Specify if you are using a TOTP two-factor code (required if your account has 2FA enabled).
- rememberPassword - Specify if you want to get a login key for subsequent logins.
- logonID - Defaults to 0 if not specified.
- machineName - Defaults to empty string if not specified.
- clientOS - Defaults to an auto-detected value if not specified.
- dontRememberMachine - Only relevant if using an authCode. Defaults to false if not specified.
- These properties must not be provided:
- loginKey
- webLogonToken
- steamID
- Individually using account name and login key
- These properties are required:
- accountName
- loginKey
- These properties are optional:
- rememberPassword - Specify if you want to get a new login key for subsequent logins.
- logonID - Defaults to 0 if not specified.
- machineName - Defaults to empty string if not specified.
- clientOS - Defaults to an auto-detected value if not specified.
- These properties must not be provided:

- steamID
- Individually using account name and client logon token obtained from the web
- NOTE: If you log on this way, webSession will NOT be emitted automatically, and you will need to use webLogOn() to get a web session.
- These properties are required:
- accountName
- webLogonToken
- steamID
- These properties must not be provided:
- password
- authCode
- twoFactorCode
- dontRememberMachine
- loginKey
- rememberPassword
- logonID
- machineName
- clientOS

$3

Logs you off of Steam and closes the connection.

$3

v3.18.0 or later is required to use this method

Logs you off of Steam and then immediately back on. If you aren't logged into an anonymous account, then you must
set rememberPassword to true when logging on initially to use this. You also must wait for the
loginKey event to be emitted before you can use this. Attempts to call this method without both
criteria being met will result in an Error being thrown and nothing else will happen.

When used, disconnected and then loggedOn will be emitted in succession. This is essentially the same as using
logOff() and then calling logOn() immediately in the disconnected event callback.

$3

SteamUser will automatically log onto steamcommunity.com when a successful connection to Steam is established (as an
individual user), but you can call webLogOn() to create a new session if your old one expires or becomes invalid.

Listen for the webSession event to get your cookies.

$3


- callback - Optional. Called when a response is available
- err - An Error object on failure, or null on success

Requests Steam to send you a validation email to your registered email address.

$3

- callback - Required. Called when the activation email has been sent.

You'll be sent an SMS with an activation code that you'll need to provide to finalizeTwoFactor.

You should save the entire response object somewhere secure. You can use JSON.stringify on it safely.

Properties of note in the response object:
- status - A value from EResult. If this is not OK (1), then the request failed.
- shared_secret - This is your secret that's used for two-factor authentication.
- identity_secret - This is your secret that's used for trade confirmation.
- revocation_code - You will need this in the future to disable two-factor authentication.

$3


- secret - A Buffer containing your shared secret

- callback - Required.
- err - An Error object on failure, or null on success

v2.0.0 or later is required to use this method

Finishes the process of enabling TOTP two-factor authentication for your account. You can use steam-totp in the future when logging on to get a code.

If TOTP two-factor authentication is enabled, a code will be required on every login unless a loginKey is used.

- callback - Optional. A function to be called once Steam receives and responds to this request.
- err - An Error object on failure, or null on success

v3.21.0 or later is required to use this method

If this account is being used to play a game on another logon session, calling this method will kick that other session
off of Steam entirely (it will get an error event if the other session is using node-steam-user).

%placeholders% in the rich presence localization value will be replaced with the value of the corresponding key that
you upload. For example, to get a TF2 RP string of "Special Event - Hello, World!", then you should upload:

"steam_display": "#TF_RichPresence_Display",
"state": "PlayingMatchGroup",
"matchgrouploc": "SpecialEvent",
