FAQ
Mobile API FAQs.
Questions we get before kicking off mobile API engineering projects.
- REST is simple, standardized, and easy to cache; GraphQL is superior when mobile screens require nested data from multiple resources in a single request, preventing over-fetching over slow mobile networks. We often implement a hybrid architecture.
