8. 8 Modeling GraphQL API's Renato Benkendorf
9. 9 Where it came from?
11. 11 Scaling GraphQL
12. 12 Scaling GraphQL 1. to multiple clients 2. cross-team
13. 13 Scaling GraphQL Aggregation layer (ESB, BFF, API Gateway, Orchestrator)
14. 14 Scaling GraphQL integrate business domains to the clients
15. 15 Scaling GraphQL
16. 16 Demystifying GraphQL
17. 17 Demystifying GraphQL QL (Query-Language) Graph
18. 18 Demystifying GraphQL Graph • The objects are vertices or nodes. • The links are edges.
19. 19 Demystifying GraphQL Query language (QL) refers to any computer programming language that requests and retrieves data by sending queries
20. 20 Demystifying GraphQL GraphQL • The nodes are the object types. • The edges are the fields.
21. 21 and what about modelling?
23. 23 Modeling a GraphQL API
24. 24 Modeling a GraphQL API data modelling
25. 25 Modeling a GraphQL API data modelling 1. Using “endpoint style” rather than thinking in graphs 2. Mapping their GraphQL schema directly to their database tables (foreign keys and all) 3. Mapping their GraphQL schema directly to their back-end data model (eg. your model classes from your ORM or the like)

36. 36 "With GraphQL, you model your business domain as a graph" Modeling a GraphQL API
37. 37 Use case
39. 39 Use case current scenario • domain business currently is servicing • domain data in redux • mapping the boundaries
40. 40 Use case next challenges • app cross-squad • app composition • manage a lot of data from different domains
