Everything you need to know to write maintainable GraphQL query documents—from variables and fragments to pagination patterns. Practical examples with curl and jq against a real API.

We've been experimenting with how Claude Code can help us migrate the functionality in FS-klienten (our legacy PowerBuilder application) to our new frontend FS Admin. The results are really promising and indicate that if we manage to use Claude correctly, this is a game changer.

I'll demonstrate how a team at Sikt used Claude to analyze screens in our legacy application, then plan and finally extend our existing GraphQL schema with the neccessary changes for this screen to be migrated.
