We don't provide out of the box functionality to track deep_link or installation events using the JS Tracker SDK, however, you can track them directly as self-describing events.
Event Schemas
For capturing deep link events, use our deep_link_received schema from Iglu Central.
For install events, use our application_install schema from Iglu Central.
Planned Improvements
For customers using our React Native Tracker SDK, we are going to release a new version that will be purely built with JavaScript (based on our JS Tracker SDK) and will also contain out of the box tracking of the deep link, install and screen events.
We will be publishing this in January, but if you are keen to try it out, install dev version 4.1.1-dev.1 from NPM. We don't recommend using this version in production.
