🌦️ Weather App – Infrastructure with Redis, RabbitMQ, Azure Key Vault and Serilog

This repository demonstrates infrastructure-focused patterns using Redis for caching, RabbitMQ for messaging, Azure Key Vault for secrets, and Serilog for logging in .NET REST APIs and Blazor Server Apps. These are built around a simplified Weather App use case, showing how infrastructure concerns can be modularized and cleanly integrated.

📦 Projects

Project	Description
WeatherApp.RestApi.UsingBackgroundService	Implements a background service for polling weather data at configurable intervals, with optional API-based triggering.
WeatherApp.RestApi.UsingCache	Implements Redis caching to store and retrieve weather data for optimized performance.
WeatherApp.RestApi.UsingRabbitMQ	Implements RabbitMQ-based message queueing to asynchronously publish and process weather updates.
WeatherApp.RestApi.UsingSerilog	Implements Serilog to log app log, transaction log and custom logs in a REST API.
WeatherApp.BlazorServer.UsingSerilog	Implements Serilog to log app log, transaction log and custom logs in a Blazor Server App.
WeatherApp.BlazorServer.UsingKeyVault	Implements Azure Key Vault to get stored secrets, to be used in a sample Blazor Server App.

Each project is self-contained and includes its own .sln file for independent testing.

▶️ Getting Started

📋 Prerequisites

• .NET 9 SDK or later
• For WeatherApp.RestApi.UsingCache: Redis server (local or remote)
• For WeatherApp.RestApi.UsingRabbitMQ: RabbitMQ server (local or remote)
• For WeatherApp.BlazorServer.UsingKeyVault: Azure subscription with Key Vault configured

🔁 Clone the Repository

git clone https://github.com/VishwamKumar/WeatherApp.RestApi.UsingRedisCache.git
cd WeatherApp.RestApi.UsingRedisCache

🚀 Run a Project

Pick one of the projects to test. For example:

cd src/WeatherApp.RestApi.UsingCache
dotnet run

Replace UsingCache with UsingRabbitMQ, UsingSerilog, UsingBackgroundService, or navigate to the Blazor projects (WeatherApp.BlazorServer.UsingSerilog or WeatherApp.BlazorServer.UsingKeyVault) to test other patterns.

🧪 Test Scenarios

Each REST API project includes a Docs/TestMe.md file with example queries and test scenarios specific to that project's functionality.
