Add Required AssetsĪt the bottom right-hand corner of Visual Studio Code, you should see a warning bar appear ( Figure 1). from the menu, navigate to the new AdvWorksAPI folder created by the above command and click the Select Folder button. NET 6 Web API app using the following dotnet command: dotnet new webapi -minimal -n AdvWorksAPI In the terminal window in VS Code, create a. Select Terminal > New Terminal from the menu.

If you wish to use VS Code for your editor and your application creation, use the following section for guidance. You also need either VS Code or Visual Studio. NET 6 on your computer, which you can get at. To get the most out of this article, I suggest that you follow along with the steps as I outline them. Let's now look at how to make this code more manageable. You can imagine how that code grows as you add the same CRUD logic for customers, employees, books, or whatever other tables you have in your database. This is a lot of code in the Program.cs file for just working with products. Listing 1: A very basic set of Minimal Web APIs // GET a single row of dataĪpp.MapGet("/product/", (int id) =>
NET 6” in the Jan/Feb 2022 issue of CODE Magazine. For a great primer on Minimal APIs, check out Shawn Wildermuth's article entitled “ Minimal APIs in. You then have the rest of your app.Map*() methods that retrieve a single product, post a new product, update an existing product and delete a product, as shown in Listing 1. In this example, I'm using hard-coded Product objects, whereas in a real application, you'd most likely use the Entity Framework to retrieve these from a database table. In the Program.cs file, you write an app.MapGet() method to return a set of Product objects. You normally have a Product class with basic properties such as ProductID, Name, Color, and ListPrice, as shown in the following code snippet. Let's look at a simple Minimal Web API system that works with product data. In this article, you're going to see how to move each group of Web APIs into their own router class to provide a much more consistent and maintainable way to create Minimal Web API calls.
For example, if you have a set of CRUD routes for working with products and another set for working with customers, create a ProductRouter class and a CustomerRouter class. Instead of keeping all your app.Map*() methods in the Program.cs file, you should create a router class to separate your groups of app.Map() methods into. NET 6, but as the number of routes grows, your Program.cs file can easily become overwhelming to maintain. It's very easy to get started using Minimal Web APIs in.
