Building Scalable APIs with ASP.NET Core

Introduction

Building scalable APIs is crucial for modern applications. In this post, we'll explore best practices for creating robust APIs with ASP.NET Core.

Setting Up the Project

First, create a new ASP.NET Core Web API project:

csharp
dotnet new webapi -n MyApi
cd MyApi

Creating a Controller

Here's an example of a well-structured controller:

csharp
[ApiController]
[Route("api/[controller]")]
public class ProductsController : ControllerBase
{
    private readonly IProductService _productService;

    public ProductsController(IProductService productService)
    {
        _productService = productService;
    }

    [HttpGet]
    public async Task<ActionResult<IEnumerable<Product>>> GetProducts()
    {
        var products = await _productService.GetAllAsync();
        return Ok(products);
    }

    [HttpGet("{id}")]
    public async Task<ActionResult<Product>> GetProduct(int id)
    {
        var product = await _productService.GetByIdAsync(id);
        if (product == null)
            return NotFound();
        return Ok(product);
    }
}
Pro Tip: Always use async/await for database operations to improve scalability.

Best Practices

  • Use dependency injection
  • Implement proper error handling
  • Add request validation
  • Use caching where appropriate
  • For more information, check out the official documentation.
