Reefact.JsonEnumValueBinding 7.0.3

Json Enum Naming

Presentation

Library for customizing enumeration values for serialization / deserialization in JSON format and ASP.Net binding

Just as the JsonPropertyNameAttribute allows customization of property names, JsonEnumValueAttribute performs the same task for enumeration values.

Reinforce the stability of your API contracts and take full control over the JSON serialization of your enumerations with the Reefact.JsonEnumValueBinding library. Designed for developers who demand uncompromising contract security, this library simplifies the customization of enumeration values, guaranteeing long-term compatibility with your customers.

Main features

🔧 Customized contract: The JsonEnumValueAttribute lets you explicitly name each enumeration value. You thus maintain a clear, documented relationship between your enumeration values and the corresponding JSON values in your API contracts.

⚓ Stability: With the fine-grained customization offered by the JsonEnumValueAttribute, future changes to your enumeration values internally no longer compromise client compatibility. Simplify JSON serialization without sacrificing contract clarity and stability. Contractual security is reinforced, allowing refactorings without risk of breakage.

📚 Documentation simplified: The use of the JsonEnumValueAttribute promotes the intrinsic documentation of your contracts, offering developers using your APIs immediate insight into the intentions behind each enumeration value.

🌐 Compatible with ASP.NET and System.Text.Json: Use JsonEnumValueAttribute to enforce customization when binding in the ASP.NET context, ensuring that your API contracts remain robust even in complex environments.

Usage

How to get started :

• Install the NuGet "Reefact.JsonEnumValueBinding" package for your project

dotnet add package Reefact.JsonEnumValueBinding

• Activate the functionality in the Startup.cs file

public class Startup {

    public void ConfigureServices(IServiceCollection services) {
        services.AddControllers()
                AddJsonEnumValueBinding(); // Binding enabled
        // ...
    }
    // ...
}

• Apply the JsonEnumValueAttribute to enumeration values in your code.

public enum ProductStatus {
    [JsonEnumValue("available")] Available,
    [JsonEnumValue("out_of_stock")] OutOfStock,
    [JsonEnumValue("discontinued")] Discontinued
}

Thus, the example below:

using Microsoft.AspNetCore.Mvc;

public class Product {
    public [JsonPropertyName("name")] string Name { get; set; }
    public [JsonPropertyName("status")] string Status { get; set; }
}

[ApiController]
[Route("api/products")]
public sealed class ProductsController : ControllerBase {

    [HttpGet("{id}")]
    public IActionResult GetProduct(int id) {
        var product = new Product {
            Name = "Widget",
            Status = ProductStatus.OutOfStock
        };

        return Ok(product); 
    }
}

produces the following result:

{
    "name": "Widget",
    "status": "out_of_stock"
}

Binding is also supported:

[ApiController]
[Route("api/products")]
public class ProductsController : ControllerBase {

    private readonly List<Product> _products = new List<Product> {
        new Product { Name = "Widget 1", Status = ProductStatus.OutOfStock },
        new Product { Name = "Widget 2", Status = ProductStatus.Available },
        new Product { Name = "Widget 3", Status = ProductStatus.OutOfStock }
    };

    [HttpGet("{status}")]
    public IActionResult GetProductsByStatus([FromRoute] ProductStatus status) {
        var productsByStatus = _products.Where(p => p.Status == status).ToList();

        return Ok(productsByStatus);
    }
}

Next call:

curl http://localhost:5000/api/products/out_of_stock

produces the following result:

[
    {
        "name": "Widget 1",
        "status": "out_of_stock"
    },
    {
        "name": "Widget 3",
        "status": "out_of_stock"
    }
]

Conclusion

Get started today and get stable API contracts, clear documentation and peace of mind when refactoring.
