Editor's Notes
- #4: Talk about nested query
- #19: The Schema first approach relies upon the GraphQL schema language, coding conventions, and tries to provide a minimal amount of syntax. It is the easiest to get started though it does not currently support some advanced scenarios. The GraphType first approach can be more verbose, but gives you access to all of the provided properties of your GraphType's and Schema. You are required to use inheritance to leverage that functionality.
- #22: MaxComplexity & FieldImpact For example if I have 3 tables with 100, 120 and 98 rows and I know I will be querying the first table twice as much then a good estimation for avgImpact would be 105.
- #24: https://graphql-dotnet.github.io/docs/getting-started/authorization
- #25: Define ObjectGraphType Define InputObjectGraphType Define query or mutation Type Define schema and register them with resolve
- #27: MaxComplexity & FieldImpact For example if I have 3 tables with 100, 120 and 98 rows and I know I will be querying the first table twice as much then a good estimation for avgImpact would be 105.
- #28: Finding real problem get you grounded about features to prioritize Think like client and see who will be using it.
