Open Source CoffeeScript Formats and Protocols

Literally Canvas is an extensible, open source (BSD-licensed), HTML5 drawing widget. Its only dependency is React.js. You can use it to embed drawing boards in web pages. It’s kind of like an extensible MS Paint in JavaScript. Users can sketch drawings and you can do what you like with the results. comes with an easy-to-use jQuery plugin. It’s developed by the community for many purposes and is free to use and extend. Literally Canvas is intended to live inside your application in the way that works best for you. There is a public API for adding new shapes and tools. Literally Canvas is optimized to work with complex drawings, and it smooths lines naturally to avoid the unsightly line angles often seen in simplistic drawing programs.

xml2js is a Node.js module that converts XML into JavaScript objects (and vice versa). It simplifies XML parsing by using pure JavaScript and supports both synchronous and asynchronous parsing. It’s a lightweight alternative to heavy DOM parsers. You can create one xml2js.Parser per file. That's the recommended one and is promised to always just work. You can call reset() on your parser object. You can hope everything goes well anyway. This behaviour is not guaranteed to work always, if ever.

json-diff is a command-line tool (and library) that computes differences between two JSON documents in a user-friendly manner. It highlights additions, deletions, and modifications in nested JSON structures, showing context so users can see where changes occurred. The output is presented in a readable diff style (text, colorized, or in various output formats) so developers can quickly understand changes between two versions of a JSON file. The tool also supports ignoring order in arrays, skipping certain paths, and configuration options so it can adapt to different JSON schemas or tolerance levels. Because JSON is ubiquitous in APIs, configs, and data interchange, json-diff is particularly handy for developers, devops, and QA to compare API responses or configuration states. It is designed to be lightweight and embeddable so it can be used both interactively and in scripts or CI pipelines.

js2coffee is a command-line and browser-based tool that compiles JavaScript code into CoffeeScript. Version 2.0 is a complete rewrite using the Esprima parser for robustness. Supports stdin and file-based inputs. Provides compatibility mode and handles JavaScript edge cases. Includes migration and hacking guides. Converts JavaScript to CoffeeScript code.

XMLBuilder‑JS provides a fluent API for building XML in Node.js. You can create elemental structures via method chaining or object literals, include comments, attributes, and streams. It’s the baseline implementation, with xmlbuilder2 available now for modern DOM compliance, namespace handling, and format conversion.
