One thing Polymer developers advocate is the idea of WebComponents. Adam Timberlake sent in an ambitious React-based framework called Maple.js (GitHub: Wildhoney/Maple.js, License: MIT, npm: maple.js) that helps you to organise React projects by using WebComponents in a very Polymer-inspired way. That means you can use React with a more Polymer-style component approach, including HTML imports, custom elements, and ES6 modules.
Given the typical Flux architecture where components reside in their respective components directory, we continue that trend in Maple, where one component can register one or many custom elements – but each HTML document can only have one template element.
Because each document only has a single
Maple solves several problems that React users have to solve when starting from scratch, so I think it's worth trying, particularly if you like Polymer. There's a getting started with Maple video where Adam demonstrates how to build an app. There's also a demo application on Heroku.
