Systems built with microservices tend to become complex over time. There are several approaches that encapsulate complex distributed system layouts with an API Gateway, or backends for frontends. Having a GraphQL gateway is one of the available options. This method of delivering client-facing APIs has become the standard with modern single-page applications.

During this talk you will:

• Discover the basics of GraphQL as the communication layer and it's core differences from REST approach
• See the real life example of how my team used Ariadne - an open-source python GraphQL server, to abstract the complexity of a large-scale, microservice-oriented system
• Learn about some common mistakes, caveats, and outtakes from taking such an approach
• Discover how deploying GraphQL as an API gateway speeds up the development process, makes the engineering team more productive and allows both, front-end and back-end engineers to shape the APIs together
