WebAssembly

The "WebAssembly" sub-platform of the Island target lets you build libraries and modules that can run in modern web browsers and interact with JavaScript.

Available APIs:

Of course any other custom, third party or open source C APIs can be imported using FXGen.

Common Projects

WebAssembly supports two common project goals:

  • Web Modules allow you build code that runs in the web browser, typically as part of a website or web application. The code can interact with the Browser object, th Document Object Model (DOM) and the HTML and JavaScript code that runs as part of the web page

  • Node.js Modules, instead, can be run in the Node.js runtime, usually as part of a larger Node.js server-side application. They can interfact with Node.js and other JavaScript that is part of the server application.

In addition to these two "application" project types, you can of course also create Static Library projects. As on the other platforms, static libraries compile to a binary file that can then be used from other (Browser or Node.js) application projects, to share code.

Additional Topics

Development, Deployment and Debugging

Development of Island apps for WebAssembly is supported in Visual Studio, Fire and Water. The Google Chrome browser needs to be installed to debug WebAssembly Web Modules in a website context, and Node.js is required to debug Node.js modules.
