Creating Dynamic Web Apps with Angular 5 and ASP.NET Core

Let’s start by talking about the tools you’ll need for your Angular/.NET project. We think Visual Studio Code and Visual Studio 2017 are great, for the most part. It might seem absurd to use two different IDEs, but we promise it will be worth it. We’ll also cover how to integrate Angular 5 into the solution project so that debugging the front and back ends only requires pressing F5.

The first step is to install the Angular CLI (Command Line Interface). It’s a useful tool that provides us with several commands for Angular development. Just enter npm install -g @angular/cli into your terminal to get going.

After configuring the Angular project, let’s focus on the ASP.NET Core backend. Everything will be covered, including how to set up authentication techniques and CORS (Cross-Origin Resource Sharing) as well as how to create a new Web API project. It’s like reaching the full potential of your ASP.NET Core backend!

Are you ready to create something really amazing? Now let’s get to work building that fantasy architecture!

Setting up the Angular Project

So you want to make dynamic web apps with Angular 5 and ASP.NET Core? Then, you’ve come to the right place! First, let’s create the Angular project.

The first step is to install the Angular CLI (Command Line Interface). It is known that there are additional command line utilities. To get started, just enter npm install -g @angular/cli into an open terminal window or command prompt. Your system will install the Angular CLI globally as a result of this.

We must configure our project to support PWA features after installing the Angular CLI. What exactly are PWA features, you might ask? These consist of service workers, icons, splash screens, offline support, and manifest, among other things.JSON. Interesting stuff, that.

Configuring PWA features requires updating the app name, icons, theme color, and other relevant information. Edit the src/manifest.json file to achieve this. Don’t forget to edit the src/ngsw-config.json file to configure the service worker to enable offline support.

We also need icons, splash screens, and offline support. After all, what good is an app if it doesn’t have an attractive splash screen and icon? You can choose which files and resources should be cached for offline access by editing the src/ngsw-config.json file.

And there you have it! You have successfully set up offline support, splash screens, icons, and PWA features for your Angular project. You’re well on your way to creating dynamic web applications with Angular 5 and ASP.NET Core. Await the subsequent stage, which involves configuring the backend of ASP.NET Core.

Setting up the ASP.NET Core Backend

The .NET Core SDK installation is the first thing you must do. By the way, SDK stands for “Software Development Kit” in case you were wondering. See? Today has already taught us something new! In any case, the official .NET Core website is where you can download the SDK. Just be sure the version you select is compatible with your operating system.

It’s time to start a new ASP.NET Core Web API project after installing the SDK. And what do you know? A few easy commands will allow us to accomplish that. It really is that simple! To get started, open your terminal (or command prompt, if you want to be fancy) and enter the following command:

dotnet new webapi -n MyApi

You might wonder, “What is “MyApi”?” It’s just the project name, after all. You are free to select any name you desire. Just be sure that it’s something that will stick in their minds and make them envious of your coding prowess.

It’s time to set up CORS and authentication for your newly created ASP.NET Core Web API project. In case you were unaware, CORS is an acronym for “Cross-Origin Resource Sharing”. It acts as a bouncer for your API, limiting access to only those who should be. Authentication is akin to a secret password that is known only by the cool kids.

Open the Startup.cs file in your preferred code editor to configure CORS. Don’t worry if you don’t have a preferred code editor; you can use whichever you like. This is the code that can be found inside the ConfigureServices method:

services.AddCors(options =>{

  options.AddPolicy(“AllowAll”, builder => {






That’s the location of the magic. You are instructing your API to grant more access by adding this piece of code. “Hey, come on in everyone, the more the merrier!” is essentially what you’re saying.

But there’s still more! A small amount of additional code must be added in order to enable authentication. In the same file, locate the Configure method and add the following code to it:


And that’s it! You’ve successfully configured the ASP.NET Core backend for your dynamic PWA in a few easy steps. Now that you’ve taken this one step toward becoming a coding pro, feel free to congratulate yourself. Continue your fantastic work!

Integrating Angular PWA and ASP.NET Core Backend

The exciting part is about to begin as we connect our ASP.NET Core backend to our Angular PWA. Get comfortable, because this is going to get real!

Transforming Angular HTTP Requests into ASP.NET Core

Now that our Angular project is operational, we would like to send some lovely HTTP requests to our backend API. However, how can we go about doing that?

Initially, we must import the HttpClient module into our Angular project from ‘@angular/common/http’. We will be able to send HTTP requests to our ASP.NET Core backend APIs thanks to this module.

After importing the module, we can use dependency injection to incorporate the HttpClient service into our Angular services or components. Using the HttpClient service’s power, we can now send GET, POST, PUT, and DELETE requests to our backend like a pro!

Authenticating Requests with JWT

Ensuring that our APIs are only accessible by authorized users is imperative. JSON Web Tokens (JWT) are useful in this situation. We can safely authenticate our requests by utilizing JWT.

We must first put in place a system on the ASP.NET Core backend for token generation and verification before we can use JWT for request authentication. After that is set up, we can add the JWT token to the headers of our Angular HTTP requests.

Managing State with RxJS

An essential component of any application is state management. In our Angular PWA, we can effortlessly manage state thanks to Angular’s robust RxJS library. We can easily write asynchronous programs and generate reactive data streams with RxJS.

The Observables and Subjects provided by RxJS allow us to store and modify the state of our application. We are able to notify other components and services that have subscribed to the state stream whenever there is a change in our state. This facilitates maintaining the synchronization of our application and offers a smooth user experience.

Styling the Angular PWA with Angular Material

Let’s now add some flair to our Angular PWA and make it shine! Angular Material has arrived to save us from the dull and uninspired user interface designs. We have access to an extensive library of pre-built, modifiable components with Angular Material.

To use their lovely components in our templates, all we have to do is import the required Angular Material modules into our app.module.ts file. Do you want a fancy submit button and a slick form field? Not a problem! All it takes is the addition of some Angular Material magic!


Our Angular PWA and the ASP.NET Core backend integration is a match made in heaven. We can use Angular Material to style our PWA, manage state with RxJS, authenticate with JWT, and make HTTP requests. For developers who want to create dynamic web apps, it’s like a dream come true. Thus, why do you delay? Connect with MegaMinds to explore the endless possibilities of transforming your ideas into impactful solutions.
