The Kopytko Framework is a renderer (React alike) that allows you to write your components directly in brs files using object literals. No extensive XML files are required anymore.
Routing, HTTP service, Store, Promise, Rx, Cache, and other tools you can use in your app.
Powerful import and mock system. You don't have to use script tags anymore. Add your dependencies directly in the brs files and they will be imported during compilation.
External modules that work with npm. They are added to the app like regular npm packages.
Kopytko Unit Testing Framework that is built on top of Roku Unit Testing Framework with additional layers that make writing tests more efficient (mocking mechanism, new assert functions and more).
ESLinter plugin to keep your code consistent and clean.
The ecosystem is open-source and tested in production. We are still improving it and adding new features.
I encourage you to try it out and let us know what you think! Please raise issues and feel free to submit PR's.
