Methods

---

addError(err [, src] [, extra])

Logs an internal Boomerang error.

If the BOOMR.plugins.Errors plugin is enabled, this data will be compressed on the err beacon parameter. If not, it will be included in uncompressed form on the errors parameter.

Parameters:

Name	Type	Argument	Description
err	string | object		Error
src	string	<optional>	Source
extra	object	<optional>	Extra data

---

addVar(name [, val] [, singleBeacon])

Add one or more parameters to the beacon.

This method may either be called with a single object containing key/value pairs, or with two parameters, the first is the variable name and the second is its value.

All names should be strings usable in a URL's query string.

We recommend only using alphanumeric characters and underscores, but you can use anything you like.

Values should be strings (or numbers), and have the same restrictions as names.

Parameters will be on all subsequent beacons unless singleBeacon is set. Early beacons will not clear vars that were set with singleBeacon.

Parameters:

Name	Type	Argument	Default	Description
name	string | object			Variable name
val	string | object	<optional>		Value. If the first parameter is an object, this becomes the singleBeacon parameter.
singleBeacon	boolean	<optional>	false	Whether or not to add to a single beacon or all beacons.

It's a good idea to set this to whatever part of your domain you'd like to share bandwidth and performance measurements across. Set this to a falsy value to disable all cookies. strip_query_string boolean <optional> Whether or not to strip query strings from all URLs (e.g. u, pgu, etc.) user_ip string <optional> Despite its name, this is really a free-form string used to uniquely identify the user's current internet connection.

---

page_ready( [ev], auto)

Method that fires the BOOMR#event:page_ready event. Call this only if you've set autorun to false when calling the BOOMR.init method. You should call this method when you determine that your page is ready to be used by your user. This will be the end-time used in the page load time measurement. Optionally, you can pass a Unix Epoch timestamp as a parameter or set the global BOOMR_page_ready var that will be used as the end-time instead.

Parameters:

Name	Type	Argument	Description
ev	Event | number	<optional>	Ready event or optional load event end timestamp if called manually
auto	boolean		True if called by page_ready_autorun

Returns:

Type: BOOMR

Parameters:

Name	Type	Description

Queryies all plugins to see if they implement readyToSend(), and if so, that they return true.

If not, the beacon cannot be sent.

Returns:

Type: boolean

True if Boomerang can send a beacon

---

real_sendBeacon()

Sends all beacon data.

This function should be called directly any time a "new" beacon is about to be constructed. For example, if you're creating a new XHR or other custom beacon, you should ensure the existing beacon data is flushed by calling BOOMR.real_sendBeacon(); first.

---

registerEvent(e_name)

Registers a Boomerang event.

Parameters:

Name	Type	Description
e_name	string	Event name

Returns:

Type: BOOMR

Boomerang object

---

removeVar(name)

Removes one or more variables from the beacon URL. This is useful within a plugin to reset the values of parameters that it is about to set.

Plugins can also use this in the BOOMR#event:beacon event to clear any variables that should only live on a single beacon.

This method accepts either a list of variable names, or a single array containing a list of variable names.

Parameters:

Name	Type	Description
name	Array.<string> | string	Variable name or list

Returns:

Type: BOOMR

Boomerang object

---

requestStart(name)

Returns:

Type: object

An object with a .loaded() function that you can call when the dynamic timer is complete.

Example

var timer = BOOMR.requestStart("my-timer");
// do stuff
timer.loaded();

---

responseEnd(name, t_start, data, t_end)

Sends a beacon for a dynamic request.

Parameters:

Name	Type	Description
name	string | object	Timer name or timer object data. Properties Name Type Argument Description initiator string <optional> Initiator, such as xhr or spa url string <optional> URL of the request
t_start	TimeStamp	Start time

Example

BOOMR.sendAll({
  metrics: {
    conversion: 1,
    size: 1000
  },
  timers: {
    customTimer1: 125
  },
  vars: {
    var1: 1,
    var2: 2
  },
  when: 9999999
});

---

sendBeacon( [beacon_url_override])

Request boomerang to send its beacon with all queued beacon data (via BOOMR.addVar).

Boomerang may ignore this request.

When this method is called, boomerang checks all plugins. If any plugin has not completed its checks (ie, the plugin's is_complete() method returns false, then this method does nothing.

If all plugins have completed, then this method fires the BOOMR#event:before_beacon event with all variables that will be sent on the beacon.

After all BOOMR#event:before_beacon handlers return, this method checks if a beacon_url has been configured and if there are any beacon parameters to be sent. If both are true, it fires the beacon.

The BOOMR#event:beacon event is then fired.

sendBeacon() should be called any time a plugin goes from is_complete() = false to is_complete = true so the beacon is sent.

The actual beaconing is handled in BOOMR.real_sendBeacon after a short delay (via BOOMR.setImmediate). If other calls to sendBeacon happen before BOOMR.real_sendBeacon is called, those calls will be discarded (so it's OK to call this in quick succession).

Parameters:

Name	Type	Argument	Description
beacon_url_override	string	<optional>	Beacon URL override

---

Sends a Custom Metric immediately

Parameters:
