Alexey Ivanov talks about the challenges and benefits involved in moving away from a REST API to a GraphQL one.

What is this talk about:

- GraphQL query language: its data types and response format.
- Differences in using a REST API and GraphQL API.
- What you need to be aware of before switching between them.

What is this talk _not_ about:

- a "how to start" guide.
- GraphQL server implementation details.
- Apollo, Relay, and other ways to work with queries on the client side.
