rollup-plugin-closure-compiler-js

Rollup plugin that invokes google-closure-compiler-js to optimize bundled JavaScript. Current stable version is 1.0.6, last released in 2017. The plugin wraps the deprecated google-closure-compiler-js (Java-based via Node) but users should note that google-closure-compiler-js itself was discontinued in 2018 in favor of google-closure-compiler (which uses the Java compiler natively). Key differentiators: simple Rollup integration, passes flags directly to the compiler. However, it is considered deprecated because the underlying closure-compiler-js package is no longer maintained.
