Metal Tools Build Rollup

Build tool for transpiling and bundling Metal.js ES6 JavaScript files using Rollup. Version 2.0.6 is the latest stable release for the deprecated Metal.js framework. It leverages Rollup's tree-shaking and module bundling to produce optimized browser-compatible bundles. Key differentiators: designed specifically for Metal.js ecosystem, supports global variable generation for browser globals, and integrates with other Metal build tools. However, Metal.js is no longer actively maintained; users should consider migrating to modern frameworks. The package has low maintenance cadence and limited documentation.
