Dev Proxy .NET Aspire extensions

Use Dev Proxy extensions for .NET Aspire to seamlessly integrate Dev Proxy into your distributed applications. Use Dev Proxy to:

• Verify how your distributed app handles API errors, both from your own services and third-party APIs
• Mock APIs while developing your app
• And more!

What This Package Does

The Dev Proxy .NET Aspire extensions allow you to easily add Dev Proxy as a resource in your distributed application. This package provides the following features:

• Add Dev Proxy as a container or executable resource to your application
• Configure Dev Proxy with custom arguments and bind mounts
• Integrate Dev Proxy with other services in your application

Usage

Here's how to add Dev Proxy's Docker container to your application:

using DevProxy.Hosting;

var builder = DistributedApplication
    .CreateBuilder(args);

// Add an API service to the application
var apiService = builder.AddProject<Projects.AspireStarterApp_ApiService>("apiservice")
    .WithHttpsHealthCheck("/health");

// Add Dev Proxy as a container resource
var devProxy = builder.AddDevProxyContainer("devproxy")
    // specify the Dev Proxy configuration file
    .WithConfigFile("./devproxy.json")
    // mount the local folder with PFX certificate for intercepting HTTPS traffic
    .WithCertFolder(".devproxy/cert")
    // mount the local folder with Dev Proxy configuration
    .WithConfigFolder(".devproxy/config")
    // let Dev Proxy intercept requests to the API service
    .WithUrlsToWatch(() => [$"{apiService.GetEndpoint("https").Url}/*"]);

// Add a web frontend project and configure it to use Dev Proxy
builder.AddProject<Projects.AspireStarterApp_Web>("webfrontend")
    .WithExternalHttpEndpoints()
    .WithHttpsHealthCheck("/health")
    // set the HTTPS_PROXY environment variable to the Dev Proxy endpoint
    .WithEnvironment("HTTPS_PROXY", devProxy.GetEndpoint(DevProxyResource.ProxyEndpointName))
    .WithReference(apiService)
    .WaitFor(apiService)
    .WaitFor(devProxy);

// Build and run the application
builder.Build().Run();

If you have Dev Proxy installed locally, you can add it as a resource instead of using the Docker container.

using DevProxy.Hosting;

var builder = DistributedApplication
    .CreateBuilder(args);

// Add an API service to the application
var apiService = builder.AddProject<Projects.AspireStarterApp_ApiService>("apiservice")
    .WithHttpsHealthCheck("/health");

var devProxy = builder.AddDevProxyExecutable("devproxy")
    .WithConfigFile(".devproxy/config/devproxy.json")
    .WithUrlsToWatch(() => [$"{apiService.GetEndpoint("https").Url}/*"]);

// Add a web frontend project and configure it to use Dev Proxy
builder.AddProject<Projects.AspireStarterApp_Web>("webfrontend")
    .WithExternalHttpEndpoints()
    .WithHttpsHealthCheck("/health")
    .WithEnvironment("HTTPS_PROXY", devProxy.GetEndpoint(DevProxyResource.ProxyEndpointName))
    .WithReference(apiService)
    .WaitFor(apiService)
    .WaitFor(devProxy);

// Build and run the application
builder.Build().Run();

Key Features

• Container Resource: Use AddDevProxyContainer to run Dev Proxy as a containerized service.
• Executable Resource: Use AddDevProxyExecutable to run Dev Proxy from the locally installed executable.
• Custom Configuration: Use the extension methods to configure Dev Proxy as needed.
• Service Integration: Easily integrate Dev Proxy with other services in your application.
