Open Source CoffeeScript Frameworks for ChromeOS

Aurora.js is a JavaScript framework that simplifies audio decode pipeline implementation—covering source, demux, decode, and playback stages. It provides high-level APIs for inspecting and playing audio, supports plugins for decoders (MP3, AAC, FLAC), works in browser and Node.js (via Browserify), and abstracts browser audio APIs.

Bone.io is a real-time web framework that streamlines building event-driven apps over WebSockets, pairing a Node.js server with a lightweight client library. It organizes communication into channels and events, so the server can push data to the browser and the browser can send commands back without boilerplate. The framework focuses on mapping server-side logic to UI updates directly, which makes patterns like live dashboards, chat, and collaborative editing easier to implement. Abstracting transport details, it lets developers concentrate on domain messages and state transitions rather than wiring up socket handlers repeatedly. The client side integrates cleanly with common frontend architectures, enabling incremental adoption in existing projects. Overall, bone.io targets teams who want a minimal, understandable real-time layer that keeps codebases small while still supporting rich, low-latency interactions.

Chaplin is a lightweight, structured JavaScript application architecture built on Backbone.js for developing scalable, maintainable single‑page applications. It provides MVC organization, clean routing, memory management, controllers for screen logic, and modular design to address shortcomings in raw Backbone. Chaplin was derived from a real application (moviepilot.com) and is written in CoffeeScript with builds in JavaScript.

Cyclotron is a web-based, drag-and-drop dashboard creation platform developed by ExpediaGroup. It enables non-programmers to build, edit, and host dashboards defined declaratively via JSON configs. Features include a built-in editor, REST API integration, Docker deployment, and extensibility for custom components. It facilitates rapid dashboard development without coding.
