Key Features

• Modular Design: Use only the components you need by adding or removing features via Nuar extensions.
• Authentication & Authorization: Supports JWT, OAuth, and custom authentication mechanisms.
• CORS Management: Effortlessly manage CORS policies using the Nuar.Cors extension.
• Custom Error Handling: Fine-tune error responses with Nuar.CustomErrors.
• Distributed Tracing: Achieve observability with Nuar.Tracing, leveraging OpenTelemetry.
• API Documentation: Automatically generate API docs with Nuar.Swagger using OpenAPI.
• Message Brokers: Integrate RabbitMQ with Nuar.RabbitMQ for microservices communication.
• Scalability & Resilience: Built with Polly for handling retries, circuit-breaking, and resilience.

Getting Started

Prerequisites

Ensure you have the following tools installed:

• .NET SDK 8.0 or later
• RabbitMQ (for message brokering)
• Docker (optional, for deployment)

Installation

1. Clone the Repository

   git clone https://github.com/ITSharpPro/Nuar.git
   cd nuar_framework

2. Restore Dependencies

   dotnet restore

3. Build the Project

   dotnet build

4. Run the API Gateway

   Navigate to the host directory and run the API Gateway:

   cd src/Nuar.Host/src/Nuar.Host
   dotnet run

Configuration

Nuar is fully configurable through YAML. Define routes, services, CORS, security policies, and more in nuar.yml:

routes:
  - path: /api/service1
    service: service1
    method: GET
    auth:
      required: true

Packaging & Deployment

• Build & Package: Use the following script to package all components:

  bash scripts/pack-all.sh

• Run Tests: To execute all unit tests, run:

  bash scripts/build-and-test.sh

Available Extensions

Nuar is designed to be modular. Below are some key extensions:

• Nuar.Cors: Manage Cross-Origin Resource Sharing (CORS) policies.
• Nuar.JWT: Add JWT-based authentication and authorization.
• Nuar.RabbitMQ: Integrate RabbitMQ for message-based communication.
• Nuar.Swagger: Generate API documentation with Swagger and OpenAPI.
• Nuar.Tracing: Utilize OpenTelemetry for distributed tracing and observability.

Contributing
