1 | # Spring for GraphQL Paging
2 |
3 | This repo contains the code for a live coding session I did on:
4 |
5 | - Spring Data JPA
6 | - GraphQL
7 | - Paging & Sorting
8 |
9 | The reason I put this together was because I was getting a few questions around how to do
10 | paging in GraphQL. GraphQL is independent of your data layer. I walked through creating
11 | some data and how to use the paging and sorting repository in Spring Data. From there
12 | your GraphQL query just needs to pass the appropriate arguments to the repository to return
13 | the appropriate results.
