ما ستصبح قادرًا عليه

  • Explain the pressure a shared general-purpose API comes under from several clients.
  • Distinguish a backend for frontend from an API gateway and from a service.
  • Decide who owns a BFF and why that ownership is the point.
  • Recognise when BFF duplication has become a problem and what to do about it.
  • Choose between a BFF, a shared API and a query-language approach on evidence.
