WATT : A novel web-based toolkit to generate WebAssembly-based libraries and applications

We present the WebAssembly Translation Toolkit (WATT), a novel WebAssembly (WASM) application authoring tool that allows developers to create a WASM-based library easily and to write WASM-based applications using the WASM library. Since WATT is a web server solution, developers can write web applications without installing any additional tools, and they can instantly run applications on a browser on a CE device or PC. Because WATT is designed to support automatic JavaScript API generation, many native libraries can be converted to WASM libraries without any knowledge of the compiler or the Emscripten tool.
