//  Handler function, invoked on every identify event
// Argument: event = event payload, settings = function settings, as of Jan 2020 it provides access to API Key value.
// Step 1. Invoke func on identify event
async function onIdentify(event, settings) {
 event.traits = event.traits || {};
 var email = event.traits.email; // Step 2. Pick up email from 'traits' obj of the incoming event
 var user_id = event.userId; // Pick up userId from the incoming event
 // Step 3. Make HTTP request to Profile API with the email from previous step
 // You can use userId value instead of email as a lookup field. In this case, insert "user_id:${userId_variable_name}" in Profile API URL instead of "email:${email_variable_name}"
 // Note '?' parameters. You can omit 'include' parameter to return all traits from the profile. 'Limit' parameter defines how many traits is returned in JSON.

Folder Structure

Motivations

• Clear feature ownership
• Module usage predictibility (refactoring, maintainence, you know what's shared, what's not, prevents accidental regressions, avoids huge directories of not-actually-reusable modules, etc)
