How to build a dynamic PWA in Angular and ASP.NET Core with a multi-tenant project.

Updated: Mar 18, 2023

Progressive Web Applications (PWAs) have become increasingly popular in recent years due to their ability to provide an app-like experience on the web. PWAs are web applications that are built using modern web technologies and can be installed on a user's device like a native app. They are fast, reliable, and provide a great user experience. In this article, we will explore how to build a dynamic PWA in Angular and ASP.NET Core with a multi-tenant project.


Before we dive into the technical details of building a dynamic PWA, let's first define what a multi-tenant project is. In simple terms, a multi-tenant project is a software application that serves multiple clients or tenants. Each client has its own data, user accounts, and preferences, but they all use the same application. A multi-tenant application can help reduce costs and simplify management for organizations that serve multiple clients.


To build a dynamic PWA in Angular and ASP.NET Core with a multi-tenant project, we need to follow these steps:

  1. Create an Angular application

  2. Add PWA support to the Angular application

  3. Create an ASP.NET Core API

  4. Create a multi-tenant database

  5. Configure the ASP.NET Core API to work with multi-tenancy

  6. Connect the Angular application to the ASP.NET Core API

Let's go through each step in detail.


Step 1: Create an Angular application

To create an Angular application, we need to install Node.js and Angular CLI on our development machine. Once we have these tools installed, we can create a new Angular application using the following command:

ng new my-pwa-app

This will create a new Angular application with some basic files and configurations.


Step 2: Add PWA support to the Angular application

To add PWA support to the Angular application, we need to install the "@angular/pwa" package using the following command:

ng add @angular/pwa

This will add the necessary files and configurations to the Angular application to make it a PWA. The "@angular/pwa" package will also generate a manifest file and a service worker file, which are required for PWAs.


Step 3: Create an ASP.NET Core API

To create an ASP.NET Core API, we need to install .NET Core SDK and Visual Studio on our development machine. Once we have these tools installed, we can create a new ASP.NET Core API project using Visual Studio.


Step 4: Create a multi-tenant database

To create a multi-tenant database, we need to design our database schema to support multi-tenancy. This usually involves adding a "tenant" column to each table that stores data for a particular client. We can use a tool like Entity Framework Core to generate our database schema from our code.


Step 5: Configure the ASP.NET Core API to work with multi-tenancy

To configure the ASP.NET Core API to work with multi-tenancy, we need to use a middleware that can identify the tenant for each incoming request. We can use the "SaasKit" middleware for this purpose. SaasKit provides a "TenantResolver" that can identify the tenant based on the host name, URL, or header of each request.


Step 6: Connect the Angular application to the ASP.NET Core API

To connect the Angular application to the ASP.NET Core API, we can use the HttpClient module provided by Angular. We can create a service in Angular that encapsulates the API calls and returns data to our components. The service can also handle the authentication and authorization of each request.


In conclusion, building a dynamic PWA in Angular and ASP.NET Core with a multi-tenant project requires a combination of front-end and back-end development skills. We need to create an Angular application and add PWA support to it. We also need to create an ASP.NET Core API and configure it to work with multi-tenancy. Finally, we need to connect the Angular application to the ASP.NET Core API using the HttpClient module.


Once we have completed these steps, we can test our dynamic PWA by running the Angular application and navigating to it in a web browser. We can then install the PWA on our device and use it like a native app. Our PWA will be fast, reliable, and provide a great user experience.


To summarize, building a dynamic PWA in Angular and ASP.NET Core with a multi-tenant project is a complex process that requires a good understanding of web development, back-end development, and multi-tenancy. However, with the right tools and skills, we can create a powerful and flexible application that can serve multiple clients and provide a great user experience.
