How to Structure an Angular + .NET 8 Microservices Project? (MVVM, MVC, Docker, Databases...)

In today's fast-paced digital landscape, building scalable and maintainable software systems is crucial for businesses to stay competitive. Microservices architecture has emerged as a popular approach to achieve this goal. In this article, we will explore how to structure an Angular + .NET 8 microservices project, covering essential topics such as MVVM, MVC, Docker, and databases.

Microservices architecture is a design approach that structures an application as a collection of small, independent services. Each service is responsible for a specific business capability and communicates with other services using lightweight protocols and APIs. This approach offers several benefits, including:

Scalability: Microservices can be scaled independently, allowing for more efficient use of resources.
Flexibility: New services can be added or removed without affecting the entire system.
Resilience: If one service fails, it won't bring down the entire application.

For our Angular + .NET 8 microservices project, we need to choose the right frameworks to implement the frontend and backend. Here are our choices:

Angular 16: A popular JavaScript framework for building single-page applications (SPAs).
.NET 8: A modern, cross-platform framework for building web applications and services.

To set up our project structure, we'll create separate folders for the frontend and backend. We'll also create a database folder to store our SQL Server database files.

project/
frontend/
angular/
src/
app/
components/
services/
...
...
backend/
net/
src/
Controllers/
Models/
Services/
...
...
database/
sqlserver/
...
...

In our Angular frontend, we'll implement the MVVM (Model-View-ViewModel) pattern to separate the application logic from the presentation layer. We'll use the @angular/core and @angular/forms modules to create our components and services.

// frontend/angular/src/app/components/user.component.ts
import { Component, OnInit } from '@angular/core';
import { User } from '../models/user.model';

@Component({
  selector: 'app-user',
  template: `
    <h1>{{ user.name }}</h1>
    <p>{{ user.email }}</p>
  `,
})
export class UserComponent implements OnInit {
  user: User;

  constructor(private userService: UserService) {}

  ngOnInit(): void {
    this.userService.getUser().subscribe((user) => {
      this.user = user;
    });
  }
}

In our .NET 8 backend, we'll implement the MVC (Model-View-Controller) pattern to handle HTTP requests and responses. We'll use the Microsoft.AspNetCore.Mvc and Microsoft.EntityFrameworkCore packages to create our controllers and services.

// backend/net/src/Controllers/UserController.cs
using Microsoft.AspNetCore.Mvc;
using Microsoft.EntityFrameworkCore;

namespace backend.net.Controllers
{
  [ApiController]
  [Route("api/[controller]")]
  public class UserController : ControllerBase
  {
    private readonly DbContext _context;

    public UserController(DbContext context)
    {
      _context = context;
    }

    [HttpGet]
    public async Task<ActionResult<User>> GetUser()
    {
      return await _context.Users.FirstOrDefaultAsync();
    }
  }
}

To containerize our application, we'll use Docker to create images for our frontend and backend services. We'll also create a Docker Compose file to orchestrate the containers.

# frontend/Dockerfile
FROM node:16

WORKDIR /app

COPY package*.json ./

RUN npm install

COPY . .

RUN npm run build

EXPOSE 4200

CMD ["ng", "serve", "--host", "0.0.0.0"]

# backend/Dockerfile
FROM mcr.microsoft.com/dotnet/core/sdk:8.0

WORKDIR /app

COPY *.csproj ./

RUN dotnet restore

COPY . .

RUN dotnet build -c Release

EXPOSE 5000

CMD ["dotnet", "run"]

# docker-compose.yml
version: '3'

services:
  frontend:
    build: ./frontend
    ports:
      - "4200:4200"
    depends_on:
      - backend

  backend:
    build: ./backend
    ports:
      - "5000:5000"

To connect to our SQL Server database, we'll use the Microsoft.EntityFrameworkCore package to create a DbContext class. We'll also create a database connection string to store the database credentials.

// backend/net/src/DbContext.cs
using Microsoft.EntityFrameworkCore;

namespace backend.net
{
  public class DbContext : DbContext
  {
    public DbSet<User> Users { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
      optionsBuilder.UseSqlServer("Server=myserver;Database=mydatabase;User Id=myuser;Password=mypassword;");
    }
  }
}

Here are some best practices to keep in mind when building your Angular + .NET 8 microservices project:

Separate concerns: Keep the frontend and backend logic separate to improve maintainability and scalability.
Use containerization: Use Docker to containerize your application and improve deployment efficiency.
Implement security: Implement security measures such as authentication and authorization to protect your application.
Monitor performance: Monitor your application's performance to identify bottlenecks and improve scalability.
