FWIW, the *entire* UI in the Music NGA re-write was built using web components. We used a combination of the gaia-components as well as some app-specific custom elements. I don’t believe either of these concerns are valid anymore. We were able to throw together web components very quickly when we needed to. Also, we are not seeing any noticeable performance impact from our heavy use of web components. I saw someone else noted a concern about the Shadow DOM API not being etched in-stone yet, which is a valid point. However, we can also make use of the excellent work Wilson has put into the base “gaia-component” class. This base class allows us to work around any gaps in the platform and also provides a thin layer of abstraction between the component and the platform. So, if things change from the API standpoint, we should (hopefully) be able to just address those changes in the base “gaia-component” class. I am hugely in favor of continuing down the web components route. Even just from a maintainability standpoint, web components were able to encapsulate all the UI complexity in the Music NGA app which kept each view’s HTML/CSS/JS code very clear and concise. -Justin > We are currently trying to identify other possibilities to achieve such a > uniform implementation - if any of you have any proposals please feel free to > reach out to Rob, Hema, or myself. > > BR > Wilfred > > > > --- > FxOS Product Management > Mozilla Corp., UK > > > > > _______________________________________________ > dev-fxos mailing list > [email protected] > https://lists.mozilla.org/listinfo/dev-fxos
