rollup-plugin-diamond

0.0.20 verified Mon Apr 27 auth: no javascript

A Rollup plugin that integrates the Diamond compiler into the build pipeline, enabling TypeScript-like compilation for Diamond source files. Version 0.0.20 is the current stable release with no scheduled cadence. Key differentiators: lightweight, zero-config for basic use, and seamless Rollup integration. Alternatives include manual compilation or other Rollup plugins for custom languages.
