Deploying ASP.NET Core 6 with Angular SPA Locally: A Step-by-Step Guide

For developers working with a Node.js front end and an ASP.NET Core backend, the process of sharing your application can seem daunting. You might find yourself questioning how to seamlessly deploy an Angular 13 application together with an ASP.NET Core 6 backend so that others can test the app without the need to install various dependencies or build the app themselves. Here, we’ll take a closer look at this problem and provide a detailed solution.

The Challenge

You’ve created both an Angular front end and an ASP.NET Core backend using the Angular template in Visual Studio. Your objective is to serve the index.html file of your Angular app through the ASP.NET Core application. You want to enable smooth testing experiences for others without necessitating additional builds or installations on their machines.

Initial Attempts

It’s common to run into issues at this stage. For instance, if you've tried implementing the following approach in your code:

But upon building and running the application, you’re greeted with 404 Not Found errors when you try to access the app. This can be frustrating, especially for those new to the ecosystem.

The Solution

After investigating, the key to solving the problem lies in the difference between building and publishing your project. Rather than running the build command, the publish command is necessary.

Step 1: Publish the Application

To correctly package your application for local deployment, use the following command:

This will create a publish folder within your Release build directory. In this folder, the necessary Angular files will now be located under the standard web content path, which is wwwroot.

Step 2: Update Your Middleware Configuration

With your Angular files now published, you’ll need to adjust your middleware configuration in your ASP.NET Core application. Here is a refined setup:

While configuring it this way may seem optimal, it’s worth noting that the standard setup should be adequate without adding custom options.

Step 3: Run the Application

Now that you’ve updated everything, run your application using the generated executable file. You can navigate to localhost:5000 in your web browser and should see your Angular app serving correctly without any errors.

Conclusion

Deploying an ASP.NET Core 6 backend with an Angular 13 front end can initially be intimidating. However, by ensuring you publish your application and properly configuring the middleware to serve static files, you can successfully create a local deployment that you can share with others for testing.

By following the steps outlined above, you can be confident that your application is packaged correctly and that it will work seamlessly on any machine without needing manual builds or installations.
