Learn how to implement data loaders in a .NET GraphQL API using Hot Chocolate.

In this video, I demonstrate the N+1 problem and implement a data loader to eliminate the N+1 problem and optimize our GraphQL resolvers.

In this series, I demonstrate how to build a GraphQL API in .NET with the Hot Chocolate NuGet package. GraphQL is a query language used for APIs that ultimately simplifies client development. Client applications only need to hit a single endpoint (usually "/graphql") in order to query the EXACT data that they need. Although client-side GraphQL development is simple, server-side GraphQL development is a bit more difficult. The goal of this series is to show how to overcome those difficulties!
