Domain Layer Order Entity The Order entity represents an order within the e-commerce system. It captures essential details related to a customer's purchase and is a core component of the Order API. Properties Id : Type: int Description: Unique identifier for the order. This serves as the primary key in the database. ProductId : Type: int Description: Identifier for the product associated with the order. This links the order to a specific product in the Product API. ClientId : Type: int Description: Identifier for the client who placed the order. This associates the order with a specific customer. PurchaseQuantity : Type: int Description: The quantity of the product purchased in the order. OrderedDate : Type: DateTime Description: The date and time when the order was placed. Defaults to the current UTC time when the order is created. Summary The Order entity is a crucial part of the Order API, encapsulating the data required to manage and process customer orders. It link

🛒 Build .NET 8 eCommerce Microservice 🚀with API Gateway, Rate Limiting, Caching & more 🧺 - [Part 2️⃣] Product Description This code defines the Product class within the ProductApi.Domain.Entities namespace. The Product class represents a product entity with properties commonly associated with products in an e-commerce application. Features Id : Represents the unique identifier for the product. It is an integer property and serves as the primary key for the product entity. Name : Represents the name of the product. It is a nullable string property, allowing the product name to be optional. Price : Represents the price of the product. It is a decimal property, ensuring accurate representation of the product's cost, including fractions of currency units. Quantity : Represents the quantity of the product available in stock. It is an integer property, indicating the number of units of the product that are available. Usage Data Representation : The Product class is used to rep

RESPONSE This code defines a C# record named Response with two properties: Flag , a boolean initialized to false , and Message , a string that defaults to null . Records in C# are immutable reference types that provide built-in functionality for value equality and concise syntax for defining data containers. GLOBAL EXCEPTION This code defines a middleware class named GlobalException for handling exceptions and specific HTTP response statuses in an ASP.NET Core application. The middleware checks for and modifies responses with status codes 401 (Unauthorized), 403 (Forbidden), and 429 (Too Many Requests). It also handles internal server errors and request timeouts by logging the exceptions and sending user-friendly error messages in JSON format. Key components of this middleware include: Dependencies : Uses Microsoft.AspNetCore.Http , Microsoft.AspNetCore.Mvc , System.Net , and System.Text.Json . Constructor : Takes a RequestDele

Ready to Scale? 🚀 Build & Run Your .NET Web API in Kubernetes with Docker! 🐳 Learn How Today! Introduction Hello, Netcode-Hub community! 👋 Frederick is here with another exciting lesson for you, we're diving into the world of Kubernetes and Docker, specifically focusing on how to build and run your .NET Web API application in Kubernetes using Docker. If you've been using Docker Compose to manage your containerized applications, you're already familiar with the convenience it brings. However, as your applications grow and require more advanced orchestration capabilities, Kubernetes becomes a powerful ally. In this section, I'll walk you through why you should consider Kubernetes over Docker Compose for orchestrating your applications, and we'll set up a practical scenario to highlight the benefits of using Kubernetes. Why Choose Kubernetes Over Docker Compose? Kubernetes and Docker Compose both serve the purpose of managing containerized applicati

🌀 How to Enhance Microservices with Ocelot API Gateway? Caching, Load Balancing, Request Aggregation and Rate Limiting! 🚀 Introduction Hello, Netcode-Hub community! 👋 In today's lesson, we're diving deeper into the world of API Gateways with Ocelot in .NET 8. If you've been following our series on microservices, you know we've already covered creating microservices with Ocelot API Gateway, restricting all API access through the Gateway, and adding JWT authentication. Today, we're going to enhance our gateway even further by introducing caching, load balancing, rate limiting, and request aggregation. These features are essential for building scalable, efficient, and reliable microservices architectures. Let's get started! Summary 1. Caching in Ocelot: First, let's talk about caching. Imagine you have an e-commerce application, and users frequently access product details. Without caching, every request would hit your database, causing

How Secure Are Your Microservices?🔒 Add JWT Authentication to Ocelot API Gateway Today!🚀 Introduction We're diving into an essential aspect of securing our microservices architecture: adding JWT authentication to our microservices that use Ocelot as an API gateway. If you've been following along, you know we've already created our microservices and set up Ocelot to redirect all API calls seamlessly. Now, it's time to add an extra layer of security. Imagine a scenario where your microservices handle sensitive data, such as user information or financial transactions. Without proper authentication, anyone could access your services, potentially leading to data breaches and unauthorized access. This is where JWT (JSON Web Token) authentication comes in. JWTs provide a compact and secure way to transmit information between parties as a JSON object. By adding JWT authentication to our API gateway, we can ensure that only authenticated and authorized us
