Many developers create a separate layer for working with APIs, but Nikita believes that this approach is inefficient — it is better to generate code from your API contract. The talk will cover the following topics: how does SDK differ from API, and why is SDK preferable for development? How can you automatically generate an SDK for Swagger and GraphQL? What should you do if you don’t have an API contract? And finally, why is it important for backend developers to understand React? The talk will help optimize development processes and simplify team interactions, making working with APIs more predictable and convenient.

<p>There are traps in the world of software development that can catch even experienced developers off guard. The talk will reveal the non-obvious aspects of using generated contracts between the server and the client, in particular, in the context of TypeScript and GraphQL. Join us to hear a story where developers face real challenges and temptations in the world of code. We'll see what consequences blind compliance with the conditions can lead to. And also we will try to find out "where is the Devil hiding in?".</p>
