How to Integrate Angular with a .NET Core Project – Let’s go to the movies!

Reading Time: 10 minutesIn this article, we are going to show you how to integrate a server-side .NET Core project with a client side Angular project. We are going to start with the server side first by creating a layer to fetch data from a database and creating an endpoint that will process the client side request and return the fetched data from the database.

After we are finished with the server side of the application, we are going to continue our work on the client part. We are going to create components to process and display the data fetched from the server with a simple interface. For that purpose, we are going to use a service to create a centralized place to handle our HTTP requests.

To create a server side of our project, we are going to use Visual Studio 2017 and for a client part the Visual Studio Code editor.

To download the complete source code check out GitHub.

So, let’s get to the action.

This post is a guest post by Marinko Spasojevic. You can read more of his work on the CodeMaze blog.

Project Preparation

Let’s start by creating a new ASP.NET Core Web Application:


After we click on the OK button, we are going to choose the Web API project:


After several seconds, the project is prepared for us.

Now, let’s open the launchSettings.json file to modify the endpoint url address and to disable our browser to start as soon as the application starts:


Because the server side and the client side projects will run on different domains we need to enable CORS on the server side project. To do that we need to open the Startup.cs class and to modify the ConfigureServices and Configure methods:

To learn more about CORS configuration and the project configuration overall, you can check out the NET Core Project Configuration article.

Configuring Entity Framework Core

We are going to use EF Core library to enable access to a database from our server application. It was installed automatically during the application creation process.

So, let’s create a new folder Models and a new class Movie inside it:

This class represents our Movie table inside a database.
Now, we need to create a context class MovieContext.cs in our project, which will be a middleware for a database communication:

After that, we need to provide a database connection string inside the appsettings.json file:

Finally, we need to register our context class in the Startup.cs class:

We have finished with the EF Core configuration in our application. We didn’t dive any deeper than we should into the configuration logic, but if you like to read about it in more detail you can check out this article .NET Core 2.0, Angular and MySQL. Repository Pattern

Creating Controller and the Get Action

Now let’s create our action that will represent an endpoint for the client request. In the SolutionExplorer we can find the Controllers folder and one class inside it. We are going to rename that class to MoviesController and to remove all the code except the first Get action:


Let’s modify our MoviesController class to fetch the data from the database by using our previously created context class:


With this code in place, we have finished with the server side. Of course, we didn’t haven’t gone too deep inside the action logic due to the sake of simplicity, but to read in more detail about all this stuff you can read .NET Core 2.0, Angular and MySQL. Get Requests.

Now we can test our Web API by sending a request from Postman or any other tool you like:
Result Server Side

Now we are ready to move on the Angular part.

Creating an Angular Project

We are going to use Angular CLI to help us with the project creation and the creation of our components. To learn more about Angular CLI, you can read Angular CLI Installation and Starting a New Project.

Let’s open the command prompt window, navigate to the location we want our application in and type the command:

After some time, our project is ready. Let’s open it inside the Visual Studio Code editor and start working on it:

Client side app

Modifying the App Component

Let’s modify the app.component.html file first:

Then, the app.component.css file as well:

If we start our application by typing ng serve in the console window of Visual Studio Code, we will get this result:

App component

When we click on the Show Movies button we should be able to see all of our movie entities on the page. So, let’s start working on that feature.

Using Services and HttpClientModule

To send a request to our endpoint, we are going to introduce the HttpClientModule in our app. So we need to import it inside the app.module.ts file and to place it in the imports array:

After the module modification, we are going to create a new folder _interfaces and to create one interface file movie.model.ts inside that folder:

Then, we are going to create a new service file http-service by using the Angular CLI command:

Created service

That looks great.

So, let’s modify that service file:

We have the getData function, which we are going to call once we require a data from a certain endpoint from the server. You can read here in more detail about services and HTTP calls.

The getData function will return an Observable as a response, so if we want to fetch that data from a response we need to subscribe on this function. So, let’s do exactly that.

Fetching and Displaying Data from the Server

Let’s modify the app.component.ts file first:

In order to display our data, we need to modify the app.component.html file by adding this code below the p tag:

Finally, let’s modify our app.component.css file:

Now if we start our application again and click on the Show Movies button, we will see this result:

Data shown

Everything works great, and our application is almost finished.

We should always try to extract part of a component into another reusable component. Maybe later on, we would like to reuse our movie list in some other component, therefore, extracting the movie list into its own component is a good solution.

Extracting the MovieList Component

First, let’s create the MovieList component:

Movie list component

Then, let’s move complete table code from the app.component.html file to the movie-list.component.html file:

After that, we are going to move the css code from the app.component.css file to the movie-list.component.css file:

After the css modification, let’s modify the movie-list.component.ts file by adding the @Input decorator:

The @Input decorator is used to accept the data sent from the parent component and it must have the same name as the movies parameter inside the *ngFor statement:

Finally, we need to inject this component into the parent component, the app.component.ts file:

As we can see, we are using a selector from our movies-list component to inject it into the parent component. Furthermore, to send our data to the @Input movies decorator, we must place its name inside square brackets. Now, as soon as we fetch data into the movies property in the app component, the data will be transferred to the movies-list component via the movies attribute.

If we start our project again and click the Show Movies button, we are going to see the same result, but this time, we have much readable and reusable code.


In this article, we have learned how to create the Angular project and to integrate it with the .NET Core Web API project.

Furthermore, we have learned:

  • How to enable communication between the projects on different domains
  • The way to use Entity Framework Core to access our database
  • How to create an endpoint for our client requests
  • To prepare an Angular application
  • How to fetch data from the server by using the HttpClientModule
  • The way to display our data by using @Input decorator in a reusable component

That is all. We hope that you have enjoyed reading this article and that you have found many useful pieces of information.
