ASP.NET Core 2 and Angular 5

By: Valerio De Sanctis

Overview of this book

Become fluent in both frontend and backend web development by combining the impressive capabilities of ASP.NET Core 2 and Angular 5 from project setup right through the deployment phase. Full-stack web development means being able to work on both the frontend and backend portions of an application. The frontend is the part that users will see or interact with, while the backend is the underlying engine, that handles the logical flow: server configuration, data storage and retrieval, database interactions, user authentication, and more. Use the ASP.NET Core MVC framework to implement the backend with API calls and server-side routing. Learn how to put the frontend together using top-notch Angular 5 features such as two-way binding, Observables, and Dependency Injection, build the Data Model with Entity Framework Core, style the frontend with CSS/LESS for a responsive and mobile-friendly UI, handle user input with Forms and Validators, explore different authentication techniques, including the support for third-party OAuth2 providers such as Facebook, and deploy the application using Windows Server, SQL Server, and the IIS/Kestrel reverse proxy.

Implementing JWT authentication


In order to handle JWT-based token authentication, we need to properly set up the ASP.NET Core Identity service to ensure that it will handle these tasks:

  • Generate a JWT token upon each username/password POST request coming from our clients
  • Validate any JWT token coming with HTTP requests by looking at the headers of the request itself

That said, the first thing to do is define the required steps we need to take care of:

  1. Add and configure the authentication service in the Startup.cs file.

  2. Update the appsettings.json and appsettings.Development.json files to store the required JWT security information (issuer and security key).

  3. Create a TokenController that will accept POST requests carrying the user credentials (username and password), validate them, and generate JWT tokens accordingly.

  4. Create an Angular LoginComponent with a Model-Driven login form to allow our users to perform the login.

  5. Create an Angular AuthService that will handle login/logout and store the JWT...
