Configuration

You may have additional information about your application's environment, current user and so on, which you want to send to your Snowplow pipeline with each event.

Setting event properties​

The tracker instance has a set of set...() methods to attach extra data to all tracked events:

Set the platform ID with setPlatform()​

You can set the platform:

t.setPlatform('{{PLATFORM}}');

Example:

t.setPlatform('mob');

If the platform is not set manually, it defaults to 'srv' (for server).

For a full list of supported platforms, please see the Snowplow Tracker Protocol.

Set user ID with setUserId()​

You can set the user ID to any string:

t.setUserId('{{USER ID}}');

Example:

t.setUserId('alexd');

Set domain user ID with setDomainUserId()​

You can set the domain user ID to any string:

t.setDomainUserId('{{DOMAIN USER ID}}');

Example:

t.setDomainUserId('e8091074-f197-4279-a92e-71a34171d477');

Set session ID with setSessionId()​

You can set the session ID to any string:

t.setSessionId('{{SESSION ID}}');

Example:

t.setSessionId('s8091074-f197-4279-a92e-71a34171d477');

Set session index with setSessionIndex()​

You can set the session index to any number:

t.setSessionIndex('{{SESSION INDEX}}');

Example:

t.setSessionIndex(10);
/* t.setSessionIndex('10'); will also work as long as input string can be converted to a valid number. */

Set network user ID with setNetworkUserId()​

You can set the network user ID to any string:

t.setNetworkUserId('{{NETWORK USER ID}}');

Example:

t.setNetworkUserId('b98c76ad-e45c-45db-a101-224718064ac2');

Set screen resolution with setScreenResolution()​

If your code has access to the device's screen resolution, then you can pass this in to Snowplow too:

t.setScreenResolution( {{WIDTH}}, {{HEIGHT}} );

Both numbers should be positive integers; note the order is width followed by height. Example:

t.setScreenResolution(1366, 768);

Set viewport dimensions with setViewport()​

If your code has access to the device's screen resolution, then you can pass this in to Snowplow too:

t.setViewport( {{WIDTH}}, {{HEIGHT}} );

Both numbers should be positive integers; note the order is width followed by height. Example:

t.setViewport(300, 200);

Set color depth with setColorDepth()​

If your code has access to the bit depth of the device's color palette for displaying images, then you can pass this in to Snowplow too:

t.setColorDepth( {{BITS PER PIXEL}} );

The number should be a positive integer, in bits per pixel. Example:

t.setColorDepth(32);

Set the timezone with setTimezone()​

This method lets you pass a user's language in to Snowplow:

t.setTimezone( {{TIMEZONE}} );

Example:

t.setTimezone('Europe/London');

Set the language with setLang()​

This method lets you pass a user's language in to Snowplow:

t.setLang( {{LANGUAGE}} );

The number should be a positive integer, in bits per pixel. Example:

t.setLang('en');

Set the IP Address with setIpAddress()​

This method lets you set an IP Address on your events:

t.setIpAddress( {{IP ADDRESS}} );

Example:

t.setIpAddress('192.168.0.1');

Set the Useragent with setUseragent()​

This method lets you override the default Useragent on your events:

t.setUseragent( {{USER AGENT}} );

Example:

t.setUseragent('myapp/0.1.0');
