Data integrity is critical. A single malformed event payload can ruin reports and cause downstream pipeline failures. TypeScript's template literal types allow us to enforce strict naming conventions across our entire tracking plan.

type EventNamespace = 'user' | 'billing' | 'project';
type EventAction = 'created' | 'updated' | 'deleted';
type TrackEventName = `${EventNamespace}:${EventAction}`;

function track(event: TrackEventName, payload: object) {
  // Implementation
}

This ensures that no developer can accidentally send 'user_login' when the system expects 'user:login', keeping the analytics database clean and queryable.
