Introduction to Peasy.NET
Peasy.NET is a versatile micro-framework developed for .NET and .NET Core environments. It is designed to assist developers in crafting business logic that is reusable, scalable, and easily testable, while maintaining a clear separation of concerns. In essence, Peasy.NET offers a robust toolkit for creating middle-tier applications that can function independently from any specific technologies used by end-users.
Understanding Middle Tier Frameworks
A middle tier framework provides a structure for developing business logic that remains distinct from user-interface and data management concerns. This approach ensures that business logic can be reused across different applications or technological environments without modification. Peasy.NET excels in this domain by offering features to maintain this separation of concerns effectively.
Key Features of Peasy.NET
Peasy.NET brings several capabilities to the table:
-
Business Rules and Validation: Peasy.NET includes a comprehensive engine for defining and enforcing business rules and data validation.
-
Multiple Client Support: It supports various client types, enabling diverse applications to interface with the same business logic seamlessly.
-
Deployment Scenarios and Scalability: Peasy.NET caters to a range of deployment scenarios and scales effectively to handle increased loads and demand.
-
Testability and Thread Safety: The framework is built with a focus on being easy to test and ensuring thread-safe operations, thus making it suitable for robust application development.
The Core Components
Data Proxy
The Data Proxy in Peasy.NET acts as a bridge for data storage and retrieval. This component abstracts interactions with data sources, be it databases, web services, or caches, ensuring that data management is modular and flexible.
Rule
Rules in the Peasy.NET world are defined to encapsulate business logic or validation logic. For example, they can determine if an action is authorized or if inputs meet specific criteria. These rules can be chained and customized to execute based on preceding rules, facilitating complex logic structuring.
Command
Commands in Peasy.NET coordinate the execution of business logic processes. They manage the invocation of initialization routines, rule execution, and any additional processing, such as fetching data via a proxy.
Business Service
Business Services in Peasy.NET represent business entities (like users or projects). They expose business functionality through commands, handling operations like create, read, update, and delete (CRUD), among others.
Deployment and Usage
Getting started with Peasy.NET is straightforward. Developers can install Peasy via Visual Studio’s package manager console or with a simple command line instruction in Visual Studio Code. Numerous resources are available in the Peasy.NET wiki to help you learn the basics and dive deeper into advanced topics. Sample implementations and consumer clients provide practical examples and are accessible for testing and experimentation.
