First you’ll need to install the package.
Before any events can be captured, you need to initialize the library. To do this, you’ll need to call the create method, and pass your API key and capture URL.
For this example, let’s say you’ve built a search component that emits a custom event when the user types in the search bar.
We can listen to the onTextInput event and call the captureSearchInput function. Inside this function, we can use the event tracker library to capture the users input. We’ll need to import the search method and also the SearchEventRequest, SearchAction, MetaData, and MetaDataKey helpers to do this.
Assuming there’s some additional logic to call an API to receive some search results, we’ll also want to capture those search results using the library. We could add another custom event to our search component, which emits the results and the search input when the component receives some results.
Then in the captureSearchResults function, we can use the event tracker library to capture the search results. We’ll need to create a MetaData object for the searchInput, so that we can pass this to the SearchEventRequest.
We’ll also need to create an array from the searchResults, mapping each result to a MetaData object. The key property should be MetaDataKey.RelatedEntity so that the library knows the result is an entity associated with the searchInput.
Once the user has received some results based on their input, it’s quite valuable to know which item they have then selected. Luckily, we can also capture this using the event tracker library.
We can add another custom event to our search component, which emits the search input and selected result when a search result is clicked.
Inside the captureResultClicked function, we can use the event tracker library to capture which result has been clicked and the searchInput that it’s associated with.
