How to build multi tenant saas application using asp net core and angular based

Introduction

Building a -tenant SaaS (Software as a Service) application using ASP.NET Core and can be a task. However, with the right approach and understanding of the technologies involved, it is definitely achievable. In this article, we will explore the steps and considerations involved in building such an application.

Understanding Multi-Tenancy

Before diving into the technical details, it is to understand the concept of multi-tenancy. In a multi-tenant application, a single instance of the software serves multiple customers, known as tenants. Each tenant has their own isolated data and configuration, while sharing the same underlying infrastructure and codebase.

ASP.NET Core for Backend

ASP.NET Core is a powerful and flexible framework for building web applications. It provides a solid foundation for developing the backend of our multi-tenant SaaS application. Here's an example of how we can our ASP.NET Core code:


// Startup.cs
 void ConfigureServices(IServiceCollection services)
{
    // Configure multi-tenancy
    services.AddMultiTenancy();
    
    // Configure database context
    services.AddDbContext(options =>
        options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
    
    // Add other services
    // ...
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // Configure multi-tenancy middleware
    app.UseMultiTenancy();
    
    // Configure other middleware
    // ...
}

Angular for Frontend

Angular is a popular JavaScript framework for building dynamic web applications. It provides a robust set of tools and features for creating the frontend of our multi-tenant SaaS application. Here's an example of how we can structure our Angular code:


// app.component.html

Welcome to {{tenant.name}}

This is the homepage of the {{tenant.name}} SaaS application.

// app.component.ts import { Component } from '@angular/core'; import { TenantService } from './tenant.service'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { tenant: Tenant; (private tenantService: TenantService) { this.tenant = this.tenantService.getCurrentTenant(); } } // tenant.service.ts import { Injectable } from '@angular/core'; import { } from '@angular/common/http'; @Injectable({ providedIn: 'root' }) export class TenantService { private apiUrl = '/api/tenants'; constructor(private http: HttpClient) { } getCurrentTenant(): Tenant { // Make an HTTP request to the current tenant // ... } }

Conclusion

Building a multi-tenant SaaS application using ASP.NET Core and Angular requires careful planning and implementation. By leveraging the power of these technologies, we can create a scalable and efficient solution that meets the of multiple tenants. With the examples provided in this article, you should now have a good starting point for building your own multi-tenant SaaS application.
