This replaces Babel for individual files and Terser for minifying output bundles.Ĭompilation using the Next.js Compiler is 17x faster than Babel and enabled by default since Next.js version 12. The Next.js Compiler, written in Rust using SWC, allows Next.js to transform and minify your JavaScript code for production. Developed and supported by Leaning Technologies, CheerpJ works on Java Swing clients, Java applets, and Java libraries.Added support for Styled Components, Jest, Relay, Remove React Properties, Legacy Decorators, Remove Console, and jsxImportSource. CheerpJ 2.1 is available for Windows, MacOS, and Linux at. Improvements in Java-JavaScript interoperability.ĬheerpJ added WebAsssembly support with release 2.0, which arrived in February.Improvements to the robustness of the ahead-of-time compiler.Improvements to the -stub-natives, a cheerpjfy.py option that creates stub JavaScript files for native methods, enabling development of browser-based implementations of native methods in JavaScript/WebAssembly.ĬheerpJ converts a Java client application into standard HTML, JavaScript, and WebAssembly, working from Java bytecode without requiring access to source code. The build size of ahead-of-time JavaScript output has been reduced as well. Version 2.1 of the CheerpJ Java-to-WebAssembly-and-JavaScript compiler, released April 6, brings optimizations to exception handling and native methods.ĭescribed as a maintenance release, CheerpJ 2.1 introduces optimizations for exception handling, which are now compiled to “much more efficient” JavaScript code, according to a bulletin on the version 2.1 upgrade. In addition, native Java reflection calls have been optimized, thus lowering the overhead in comparison with standard Java calls.
