Solution Overview

Problem

The complexity of maintaining and distributing micro front-ends (MFEs) in user interfaces, along with the risk of deploying MFEs in inappropriate contexts that may expose applications to security vulnerabilities.

Innovation Solution

Implementing use-constrained user interface component distribution, where a service accepts a call context for MFE requests and compares it to a stored use context. If the call context meets the defined parameters, the service provides the MFE; otherwise, it returns an error message.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If micro front-ends are distributed freely to enable flexible UI component management, then adaptability and ease of operation are improved, but security vulnerabilities and harmful factors increase due to inappropriate context deployment

Engineering Contradiction:

Improveflexibility in UI component managementVSAvoidsecurity vulnerabilities

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A use context verification service is introduced as an intermediary between MFE providers and consumers. The service receives MFE requests, verifies the call context against stored use contexts, and only allows access if the context matches. This mediator enables flexible distribution while preventing security vulnerabilities by blocking inappropriate deployments.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If use context verification is implemented to prevent security vulnerabilities, then reliability is improved, but device complexity increases due to additional verification mechanisms

Engineering Contradiction:

Improvesecurity against vulnerabilitiesVSAvoidcomplexity of distribution system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The verification system is segmented into distinct components: a use context storage repository, a verification service, and client-side request handlers. This segmentation allows each component to be developed, maintained, and scaled independently, reducing overall system complexity while maintaining high reliability through specialized security verification.

Inventive Principle:

Principle #1Segmentation

3Reliability

If strict use context constraints are applied to limit MFE distribution, then security and reliability are improved, but ease of operation decreases due to additional verification steps

Engineering Contradiction:

Improveintegrity of user interfacesVSAvoidease of MFE deployment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system implements self-service verification where the verification service automatically compares call contexts against stored use contexts without requiring manual intervention. The client-side code automatically handles the verification process, eliminating the need for operators to manually configure security rules while maintaining strict integrity constraints.

Inventive Principle:

Principle #25Self-service

AI summary

System and techniques to provide use constraints when distributing user interface component are described herein. A request for a user interface component is received with a call context. This call context is matched to a local use context that embodies constraints on use of the UIC. Corresponding call context values are compared to the use context to determine whether the use of the user interface component is compliant. If the use is compliant, the user interface component is served in response to the request; otherwise the user interface component is not served.
