closure-compiler-js packages Google’s Closure Compiler so it runs under JavaScript (e.g., Node.js) instead of a JVM, making advanced JS optimization accessible in more build pipelines. You get the same aggressive whole-program optimizations—dead-code elimination, property renaming, inlining, and cross-module motion—delivered via a JS API and CLI. Because it’s the compiler you know, it also honors Closure type annotations and JSDoc, enabling type-aware rewrites that shrink bundles without breaking semantics. The distribution is geared for tool authors: plug it into bundlers, custom scripts, or CI without dragging in a Java runtime. It’s particularly handy in constrained environments (serverless, sandboxed workers) where spawning a JVM is undesirable. In short, it brings Closure’s battle-tested optimizer to the places modern JavaScript actually runs.
Features
- Advanced optimizations beyond minification in a Node-friendly package
- JSDoc/Closure types for safe renaming and inlining
- CLI and programmatic API for build tools and scripts
- Cross-module code motion and tree-shaking for smaller bundles
- Works in JVM-less environments like serverless and constrained CI
- Drop-in replacement path for teams already using Closure Compiler
