DryIce is a JavaScript‑only build tool for bundling CommonJS and RequireJS modules into a single browser‑ready script. It lets developers specify source files (via paths, globs, functions or CommonJS dependency graphs), optionally run filters such as UglifyJS or base64 encoding, and output the concatenated result to a file or data object—providing a lightweight alternative to RequireJS’s Java‑based optimizer. It’s aimed at front‑end developers who want a pure‑Node build process for packaging and minifying their modular JavaScript.
