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.
