node. JS Application Layer Framework Bearcat overview

Bearcat is a POJOs-based application-layer framework developed by NetEase, Bearcat provides a lightweight container to write simple, maintainable node. js. Bearcat provides a basic underlying to manage application logic objects, allowing developers to focus on the logic of the application layer. Bearcat enables developers to write "simple, pure JavaScript objects" (POJO) and does not hack into these POJO, and you can deploy the POJO in an environment that does not use Bearcat.

Bearcat overview
Bearcat includes several parts, including:

Core container
The core container contains the core, Beans, and context modules.

The core and beans modules provide the basic parts of the container, including IOC containers and dependency injection. Beanfactory is a complex factory factory pattern implementation. It goes beyond manually writing a singleton to allow your actual program logic to be decoupled from configuration and dependency management.

The Context module is based on the core and beans modules, and provides some more advanced content, ApplicationContext is its main implementation.

Plane-oriented programming

Bearcat provides aspect-oriented programming (AOP) support based on the core container, allowing the developer to define, method interceptors, and slice to solve even the business logic that needs to be separated.

Characteristics
Lightweight containers
* Dependency Injection (DI) implementation of control inversion (IoC) to manage POJOs
* AOP-based declarative crosscutting logic
* Consistent development and configuration

Simplicity of

* Simple metadata configuration and writing POJOs
* Light weight: Efficient development based on node. js
* Reusable: POJOs can be applied to any development environment
* Non-intrusive: development without dependency on the container API
* modularity: Use the parts that you need
* One-stop service: No need to manually write Singleton and factory methods

Powerful

* Good reference: complete documentation, many examples include Web Todo, realtime app

* Good testing: over 95% test coverage

Can be extended

* Custom Extensions: You can add custom code to the container
