• High-Performance JavaScript/TypeScript Transpilation: Replacing Babel with a Rust-based compiler up to 20x faster.
• Next.js & Modern Bundler Pipelines: Transpiling React JSX, TSX, modern ECMAScript features, and Webpack/Turbopack assets.
• Programmatic AST Manipulation & Code Generation: Building fast custom build tools using the @swc/core Node.js API.
• Production Asset Minification: Minifying JS and CSS bundles at extreme speeds using @swc/core minifier.
