Today I built a lightweight Web API using 𝗔𝗦𝗣.𝗡𝗘𝗧 𝗖𝗼𝗿𝗲 𝗠𝗶𝗻𝗶𝗺𝗮𝗹 𝗔𝗣𝗜𝘀 and 𝗘𝗻𝘁𝗶𝘁𝘆 𝗙𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸 𝗖𝗼𝗿𝗲, adding 𝗮𝘂𝘁𝗵𝗲𝗻𝘁𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝗮𝗻𝗱 𝗮𝘂𝘁𝗵𝗼𝗿𝗶𝘇𝗮𝘁𝗶𝗼𝗻.

Minimal APIs help reduce boilerplate code and are ideal for small services or microservices.

Here’s what I implemented:

• CRUD operations for a simple TaskItem model.
• Integrated EF Core with a SqlServer database.
• Secured the API using JWT-based authentication and role-based authorization.

𝗘𝘅𝗮𝗺𝗽𝗹𝗲: 𝗗𝗲𝗳𝗶𝗻𝗶𝗻𝗴 𝗮 𝗿𝗼𝘂𝘁𝗲

RouteGroupBuilder taskItems = app.MapGroup("/tasks");

taskItems.MapGet("/{id}", GetTask)
.RequireAuthorization();

static async Task GetTask(int id, AppDbContext db)
{
return await db.Tasks.FindAsync(id)
is TaskItem task
? TypedResults.Ok(new TaskItemDTO(task))
: TypedResults.NotFound();
}

𝗘𝘅𝗮𝗺𝗽𝗹𝗲: 𝗔𝗱𝗱𝗶𝗻𝗴 𝗮 𝘁𝗮𝘀𝗸

taskItems.MapPost("/", CreateTask)
.RequireAuthorization();

static async Task CreateTask(TaskItemDTO taskItemDTO, AppDbContext db)
{
//Convert DTO to model.

db.Tasks.Add(taskItem);
await db.SaveChangesAsync();

taskItemDTO = new TaskItemDTO(taskItem);

return TypedResults.Created($"/taskitems/{taskItem.Id}", taskItemDTO);

}

This approach is clean, fast, and perfect for RESTful APIs.
