Catberry

Catberry is an isomorphic framework for building universal front-end apps using components, Flux architecture and progressive rendering. Catberry builds a bundle for running the application in a browser as a Single Page Application. Cat-Components – similar to web-components but organized as directories, can be rendered on the server and published/installed as NPM packages. The entire architecture of the framework is built using the Service Locator pattern, which helps to manage module dependencies and create plugins, and Flux, for the data layer. Search crawler receives a full page from the server. The whole state of the application is restored from URL. Server-side progressive rendering based on node.js streams and parallel rendering of components in a browser. The framework is well-tested (code coverage is about 90%) and it is already used in production.
