How can I build a flexible plugin architecture for Go applications without modifying the core?

Events and Plugin Architecture in Go: An Analysis

In this query, the user explores ways to implement event handling and plugin integration in Go. They seek a comprehensive solution that allows for seamless integration without modifying the core application.

Event Handling in Go

While events are not directly supported in Go's core, channels serve as a powerful mechanism for asynchronous communication. Interface can be leveraged for plugins.

Plugin Architecture Using Interfaces

The proposed plugin architecture relies on interfaces. Plugin types define their respective behaviors through interfaces. These interfaces can then be registered in a central plugin registry.

Plugin Registration and Integration

Importing the plugin packages automatically registers them within the registry. This approach eliminates the need for complex reflection techniques.

Plugin Execution in Core

The core application iterates through the registered plugins, executing the methods defined in the respective interfaces.

Conclusion

The proposed solution provides a flexible mechanism for plugin integration and extension points without the need for dynamic linking or recompilation. This approach allows for a cleaner separation of concerns, enabling the development of truly extendable applications in Go.
