    API Design Patterns Every Startup Should Know

    Your API is your product's contract with the world. Here are the patterns that will keep that contract clean and maintainable.

    Use GraphQL when your frontend needs are diverse and the backend data model is complex. But don't use it just because it's trendy.

    Conclusion

    Choose the API style that matches your use case. REST for simple CRUD, GraphQL for complex frontends, gRPC for service-to-service communication.
