Target keyword: graphql grpc asp.net core · Read time: ~32 min · .NET: 8 / 9 · Project: ShopNest Multi-Protocol API Gateway

Introduction

ShopNest public partners use REST; internal services use gRPC; mobile apps may prefer GraphQL (Hot Chocolate) — choose the right protocol per client.

After this article you will

  • Compare REST vs gRPC vs GraphQL honestly
  • Add Hot Chocolate GraphQL endpoint
  • GraphQL queries, mutations, subscriptions
  • OData for rich REST querying
  • Multi-protocol gateway pattern

Hands-on build guide — ShopNest Multi-Protocol API Gateway

  1. GraphQL /graphql endpoint for products + categories.
  2. gRPC InventoryService from Article 53 side-by-side.
  3. YARP gateway routes /api → REST, /graphql → GraphQL.

Common pitfalls

  • GraphQL N+1 queries — use DataLoader.
  • Exposing GraphQL without auth — depth/complexity limits required.

Interview & portfolio questions

Q: When GraphQL?
A: Many clients need different field sets — one endpoint, client specifies shape.

Summary

  • Not every API must be REST — match protocol to client
  • ShopNest uses REST public + gRPC internal
  • GraphQL optional for mobile flexibility

Next: Rate Limiting

FAQ

OData still used?

Yes for enterprise REST clients wanting $filter/$expand.

GraphQL subscriptions?

WebSocket transport — similar plumbing to SignalR.
