Spartacus Tracking Library
Spartacus' tracking library offers a various set of features related to support, e.g. the TMS support (including the support for Adobe Launch, GTM, etc.) and also the personalization feature.
It can be added to the existing Spartacus application by running ng add @spartacus/tracking. For more information about Spartacus schematics, visit the official Spartacus schematics documentation page.
