A lightweight, URI-based message broker for Dart applications.

Changelog

0.5.0

Breaking Changes

• Removed result field from BusPacket and consolidated response data into payload field
• Removed SystemBusClient and HttpSystemBusClient classes to reinforce protocol-agnostic design
• Removed HttpVerb enum from core package (clients should define their own protocol verbs)

Added

• Added errorCode field to BusPacket for more structured error reporting
• Updated documentation with Protocol Implementation Guide section
• Enhanced error reporting in SystemBus.sendRequest() to include error codes

Changed

• Updated tests to reflect new packet structure and removed client-specific tests
• Simplified architecture by removing unnecessary abstractions
• Improved protocol-agnostic approach by eliminating HTTP-specific components

0.4.2

Fixed

• Removed URI scheme restriction that was preventing non-'bus' protocols from utilizing the bus architecture
• SystemBus now routes messages based solely on host and port, without validating or restricting the URI scheme
• Added tests to verify support for domain-specific URI schemes (e.g., 'fs://', 'net://', etc.)
