How does AngularJS handle large-scale API orchestration in frontend architecture?

AngularJS handles API orchestration using services, interceptors, and chained promises.

In enterprise systems, multiple APIs must be coordinated to build a single view. AngularJS uses service layers to abstract API calls and $q promises to chain asynchronous operations. Interceptors manage authentication, logging, retries, and error normalization. This creates a structured orchestration layer in frontend architecture.
