CheerpJ enables bidirectional Java-JavaScript interoperability.The JavaScript code generated by CheerpJ is highly optimised and garbage-collectible.The runtime supports WebAssembly for optimal performance and size. It supports audio, printing, and any other Java SE component. CheerpJ comes with a full Java SE runtime, inclusive of Swing/AWT.
CheerpJ works directly on Java bytecode, and does not require access to the Java source code.
CheerpJ can convert 100% of Java including reflection and proxy class creation, with no manual intervention on the code. The CheerpJ on-the-fly Java-to-JavaScript compiler, a reduced JavaScript version of the CheerpJ compiler that can be distributed with applications converted with CheerpJ to enable dynamic features of Java such as reflection. The CheerpJ runtime library, a full Java SE runtime in WebAssembly and JavaScript, that can be distributed in part or in full with applications converted with CheerpJ. The CheerpJ AOT compiler is available for Linux, macOS and Windows. This can be used to convert Java archives (e.g.jar) or single. The CheerpJ AOT compiler, an LLVM-based Java-bytecode to JavaScript compiler. What is CheerpJ?ĬheerpJ is constituted of three components: If you are unsure how to start, try our Tutorial. CheerpJ is a Java bytecode to WebAssembly and JavaScript compiler, compatible with 100% of Java, which allows to compile any Java SE application, library or Java applet into a WebAssembly/JavaScript application.
