The PatternFly roadmap outlines a proposal to scale framework support by adopting a Web Component based solution for implementing pattern behaviours to support multiple web frameworks.
By building prototypes for PatternFly-webcomponents, we have shown that framework integration of web components is possible, but benefits from the introduction of framework-specific shims to provide application developers with a framework-native experience when consuming the web components.
Front-end developers are by-and-large in favor of the web component approach for implementing pattern behaviours. However, we need to achieve a critical mass of pattern implementations in order for developers to adopt the solution and begin contributing back their own implementations.
