Command Bus Pattern
The Command Bus pattern is a design pattern used in software engineering that provides a mechanism for executing commands in an application in a decoupled and extensible way. The Command Bus pattern is especially useful in the context of Domain-Driven Design, where commands are used to represent actions that can be performed on domain objects.
The Fractal Framework includes a powerful Command Bus system that enables developers to implement the Command Bus pattern in their applications. With the Fractal Command Bus, commands are defined as simple data objects that encapsulate the information needed to execute an action on a domain object.
When a command is executed, it is passed through the Command Bus, which determines the appropriate handler for the command and executes it. The Command Bus also provides a mechanism for validating commands and handling errors, which can help to ensure that commands are executed correctly and consistently.
By using the Command Bus pattern, developers can achieve a higher level of decoupling and abstraction in their applications, which makes it easier to maintain and extend the system over time. The Fractal Framework's Command Bus system is a powerful tool for implementing the Command Bus pattern in applications, providing developers with a flexible and extensible platform for building high-quality, domain-driven applications.
