Let’s walk through a more detailed step-by-step process with code for a more comprehensive API Gateway using YARP in ASP.NET Core. We’ll consider a simplified scenario with two microservices: UserService and ProductService. The API Gateway will route requests to these services based on the path.
Step 1: Create Microservices
Create two separate ASP.NET Core Web API projects for UserService and ProductService. Use the following commands:
dotnet new webapi -n UserService
dotnet new webapi -n ProductService
Step 2: Install YARP Packages
Add the YARP NuGet packages to both microservices projects:
# For UserService
dotnet add package Microsoft.ReverseProxy –version 2.11.0
dotnet add package Microsoft.ReverseProxy.Telemetry.Consumption –version 1.0.0
# For ProductService
dotnet add package Microsoft.ReverseProxy –version 2.11.0
dotnet add package Microsoft.ReverseProxy.Telemetry.Consumption –version 1.0.0
