GraphQL in Microservices using ASP.NET Core Web API | Hot Chocolate Complete Implementation Guide

GraphQL in Microservices using ASP.NET Core Web API | Complete Implementation with Hot Chocolate In this video, we will implement GraphQL in a Microservices Architecture using ASP.NET Core Web API and Hot Chocolate. Modern applications often struggle with over-fetching and under-fetching problems in REST APIs. When multiple frontend clients such as Web, Mobile, and Admin dashboards require different shapes of data, traditional REST APIs become rigid and inefficient. In this complete step-by-step video, we implement GraphQL inside the API Gateway as a Backend for Frontend (BFF) layer. You will learn how GraphQL acts as a flexible data-fetching layer that aggregates data from multiple microservices like Order, Product, User, and Payment services. This video covers: • Why REST becomes insufficient in modern UI-driven applications • What is GraphQL and how it solves over-fetching and under-fetching • GraphQL vs REST detailed comparison • Implementing GraphQL using Hot Chocolate in ASP.NET Core • Creating Input Models and Output Models • Defining GraphQL Input Types and Output Types • Implementing Queries and Mutations • Using GraphQL in API Gateway as BFF • Clean architecture integration with microservices • Real-time Order Details and Place Order scenario We build a real-world example where GraphQL aggregates data from multiple microservices and returns a flexible response tailored to different UI screens. This Video is perfect for: ASP.NET Core developers Microservices architects Backend developers System design learners Full-stack developers If you want to build scalable, flexible, and modern APIs using GraphQL with ASP.NET Core Web API, this video is for you.
