Micro-Frontend Communication Handlers for Cross-Context Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing micro-frontend architectures face compatibility issues and code duplication due to different browser contexts, leading to communication limitations and resource wastage.
Innovation Solution
A communication system with wrapper and micro-frontend message handlers that use a shared communication channel to facilitate bidirectional data exchange between wrapper applications and micro-frontends, independent of browser contexts, using unique identifiers and predefined messaging schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different communication techniques are used for different browser contexts (iFrame vs. web worker), then compatibility with specific micro-frontend types is improved, but device complexity and code duplication increase
Solution Approach 1:
The patent implements a universal communication interface that works across different browser contexts (iFrame, web worker, same-context) through a standardized message passing protocol. The wrapper application and micro-frontend both implement common interface methods (sendMessage, receiveMessage, sendMessageAsync, receiveMessageAsync) that abstract away the underlying context differences, allowing the same code to function universally across all browser contexts without duplication.
Solution Approach 2:
The patent introduces message handlers as intermediary components that mediate communication between the wrapper application and micro-frontend. These handlers serialize and deserialize messages, manage communication state, and handle context-specific implementation details, allowing the main application logic to remain context-agnostic while still supporting multiple browser contexts through the intermediary message handling layer.
2Device complexity
If a universal communication interface is implemented across all micro-frontend types, then code duplication is reduced, but adaptability to specific browser contexts may be compromised
Solution Approach 1:
The patent applies local quality by implementing context-specific message handling within a universal interface framework. Each browser context (iFrame, web worker) has its own message handler implementation that adapts the universal communication protocol to context-specific requirements. This allows the majority of the codebase to be universal and non-duplicative, while only the necessary local adaptations are context-specific.
3Adaptability or versatility
If message handlers use serialization and deserialization for communication, then communication flexibility across contexts is improved, but processing time increases
Solution Approach 1:
The patent implements partial serialization by selectively serializing only the necessary message data rather than entire objects or complex structures. The message handlers serialize message content, unique identifiers, and type information, but avoid serializing large data structures or objects that can be referenced by identifier. This reduces the overhead of serialization/deserialization while maintaining communication flexibility across different browser contexts.
Data Source
AI summary
A communication system for a micro-frontend architecture can include a first message handler associated with a requestor of data and a second message handler associated with a requestee. The requestor can be a wrapper application or a micro-frontend, and the requestee can the other of the wrapper application or the micro-frontend. In response to receiving a data request from the requestor, the first message handler can transmit a request message via a communication channel to the second message handler, where the request message includes a unique identifier assigned to the request. Thereafter, the first message handler can receive a response message from the second message handler via the communication channel, where the response message includes the data and the unique identifier. Based on the unique identifier in the response message, the first message handler can provide the data to the requestor in a response to the request.
