opus-messenger
The opus-messenger project is primarily an application interaction tool that allows different segments/modules (or frames) of an application to communicate seamlessly. It is an intricate messaging system with advanced transaction handling and message routing capabilities.
Purpose
The primary purpose of the project is to allow different entities, possibly located in separate frames within an application, to engage in synchronized and controlled communication, thus enhancing the interoperability of the application's subsystems.
Key Functionality
Connection Handling
The module can establish connections between different frames within the application. By providing a 'targetWindow' parameter, an application segment can reach out to another and establish mutual communication.
Service Registration and Proxy
The opus-messenger allows for services to be registered and exposed for consumption by other modules. A service registered in one module can be consumed by another via a proxy mechanism, optionally with an alias. The project implements robust service registration checks to prevent duplication of service names.
Multiple Message Handlers
A range of transaction handlers can be implemented, from 'connect' and 'ping' to 'echo', and more. Services can respond to a variety of transaction types and ensure that the correct message handler processes the incoming event or message.
Message Channeling
The project implements a concept of 'clients' as an aggregation of message channels. Each individual 'client' is in essence an individual communication instance. There are also measures in place to deal with transaction timeouts, preventing stale or long-running transactions.
Parent Finder
The opus-messenger can identify a module's 'parent' if it exists. This is useful in a hierarchical frame layout where tracking frame lineage might be necessary.
Message Dispatch and Reception
The project can dispatch messages to targeted modules and equally process incoming messages, routing them to the right registered services or necessary handlers.
Error Handling
The project is careful to reject actions that are logically impossible or would create cyclical communication links, such as attempting to connect a module to itself or registering a duplicate service name. This ensures a streamlined and error-minimized operation.
In summary, the opus-messenger project serves as a foundation for simplified, error-free, and controlled interaction across different modules of an application.
