Why It's Not so Easy to Migrate to GraphQL

I will talk about the experience of migrating from REST to GraphQL in the Yandex Real Estate and Yandex Rental services. We will look step by step at how we work with the GraphQL schema, why we wrote our own GraphQL client, and how development processes have changed after switching to GraphQL. I’ll tell you what difficulties we encountered during integration in the thick client.

The talk will explore a fundamental problem that may arise at BFF and how it can be solved.
